Keep the Exposed Band of a Sub-Cell Step Beside the Neighbouring Layer's Outer Wall

On a shallow surface the band of a layer that the layer above leaves exposed is narrower than a grid cell, so whether the layer is the topmost occupant of any cell flickers from layer to layer and the band's segments, inner walls and solid infill hidden by role, came and went in a dashed ring. That band is always in the same place: the strip just outside the outer wall of the layer above, or of the layer below for the underside of an overhang. The classifier now keeps the outer-wall cell map of the previous and next layers as well as the current one, rotating like the footprints, and keeps any segment whose midpoint lies within a line and a half, or a cell if larger, of a neighbouring layer's outer wall. It can only add segments, so no hole is opened by it; what it over-keeps is the covered strip under the neighbour's wall.

-name: Daily OFL OTA Update
-
-# This workflow is intended for creating and publishing the OrcaFilamentLibrary (OFL) OPC package to
-# https://github.com/OrcaSlicer/orcaslicer-profiles, which generates an OTA update.
-# This cronjob runs daily at 00:00 UTC every day and scans main plus every release/vX.Y.Z branch for
-# changes to resources/profiles/OrcaFilamentLibrary since that branch's own last successful run. Any
-# branch with no changes is skipped; each changed branch gets its own post_merge_profiles.yml dispatch.
-#
-# OFL has no dedicated FOLDER_MERGERS grant (it isn't merged through the PR merge-bot delegation
-# scheme), so post_merge_profiles.yml is dispatched with an explicit `vendor` input, which that
-# workflow trusts and uses to bypass the FOLDER_MERGERS check for this trigger. That same explicit-
-# vendor-dispatch path is also what makes post_merge_profiles.yml call the OTA auto-publish API after
-# uploading - see post_merge_profiles.yml for both sides of that contract.
-#
-# At the start of each run, the pending-publish table is cleared up to a captured
-# timestamp (POST /api/v1/ota/ofl/pending/clear?timestamp=...). Changes merged after
-# that timestamp remain pending for the next run.

-# Deferred Page Construction: High Level Design
-
-## Why it exists
-
-The main window is a notebook of tabs, and only one of them is on screen when the first
-frame appears. Others are opened later in the session, some never, and some only exist
-for certain printers. Building every tab before the first frame makes each startup pay for
-tabs the user may never open.
-
-This subsystem builds a tab the first time it is shown, and builds the rest in small units
-while the user is idle after startup. Startup pays only for what the first frame shows,
-the other tabs are usually ready before anyone opens them, and a click that lands in the
-middle of the idle build waits for one unit at most. Work that is not a tab, such as a
-dialog or the 3D view's GL resources, uses the same machinery.
-
-## The parts
-
-The parts are independent. A holder can hold anything a factory makes, a placeholder page
-is a holder with a widget, a staged object can live outside a holder, and the scheduler
-knows none of them; it runs tasks, which the main window makes from the holders.
-
-### The holder: `Lazy<T>`
-
-A holder keeps one object and the factory that makes it. The rest of the app reads the
-object if it exists, makes sure it exists now when about to show or navigate to it, or runs
-something once it exists. A type with one instance in the app gets these as statics
-through `LazyInstance<T>`, so callers need no reference to the main window, and all of them
-are harmless while no holder exists.
-
-The holder guarantees that callers see the object only once it is completely built. A
-build cannot re-enter itself, so a nested request finds nothing yet, and a factory that
-returns null or a unit that throws leaves the holder and the scheduler able to carry on.
-The holder does not own the object; its wx parent does, as for any window. The holder has
-no wx dependency and is unit-tested.
-
-### The placeholder page: `LazyPage<Panel>`
-
-The notebook needs a page object for a tab to exist and for tabs to be inserted and
-removed by pointer, and the placeholder is that object. It builds the real panel inside
-itself the first time it is shown and forwards showing and hiding afterwards, so a panel's
-own show handling stays its activation hook. Nothing builds while the main window is
-hidden; the window's first show builds the start page. A page that is out of the book is
-not prebuilt. A panel built while its page is hidden stays hidden, and gets the theming
-the window applied before the panel existed.
-
-### Staged construction: `StagedBuild`
-
-A constructor too big to be one unit builds a skeleton and queues the rest as steps, which
-run one per unit. A child panel's steps can be forwarded to its parent, and the parent is
-complete only once the child is. Nothing may use what a step builds before the last step
-has run, so staged panels follow these constraints:
-
- members created in steps start out null, so a partly built panel can be destroyed;
- timers, event handlers and destructors that touch step content check that the panel is
-  complete first;
- nothing takes focus while off screen, since a unit may run while the user is typing
-  elsewhere;
- a widget added by a step keeps its place in the sizer through an empty slot the skeleton
-  creates.
-
-### The scheduler: `IdleScheduler` and `PrebuildQueue`
-
-The queue holds tasks in order, and a slice runs units of the first pending task until
-the task finishes, the time budget is spent, or input arrives. It has no wx dependency and
-is unit-tested with a fake clock. A task whose work goes away, such as a tab removed from
-the book, is skipped, and becomes pending again if the work comes back.
-
-A slice runs only once the user has been idle for a short quiet time, and each slice is its
-own timer message, so paint, timers and input queued in between are handled before the
-next slice. Posting slices as pending events would not do that, because wx drains every
-pending event before the next native message. On GTK a timer that is always due starves
-the lower-priority sources that repaint and deliver posted events, so slices are a few
-milliseconds apart. On Windows a slice also waits while the native queue holds input,
-not counting mouse moves, which Windows synthesizes whenever a window appears under the
-cursor. A slice never runs inside a `wxYield()`, where it would build pages in the middle of
-the code that yielded. A unit cannot be interrupted, so the largest unit bounds how long a
-click can wait.
-When nothing is pending the timer stops and the subsystem costs nothing.
-
-The main window owns the scheduler because it owns what the tasks build, and clearing the
-queue with the window keeps a task from outliving its object. Each owner provides its own
-tasks, such as a tab, a dialog, the Prepare tab's settings page one option group at a
-time, the Prepare page's layout at the size the book gives its pages, or the 3D view's GL
-resources.
-
-### The 3D view's GL resources
-
-OpenGL is loaded on the Prepare tab's canvas. When the start page is not Prepare, loading
-it is an idle task that makes the context current on the hidden canvas, so the start page
-paints first and Prepare never appears. Loading it on a shown canvas under `Freeze()` holds
-back the start page's paint, and on GTK `Freeze()` cannot hide the canvas, which is a
-native child window or a Wayland subsurface drawn outside GTK. A hidden Windows child
-window keeps its device context, macOS attaches the context to a hidden view, and GTK
-creates the canvas's surface when the widget is realized, so on GTK the task realizes the
-canvas first. If the context cannot be made current, the canvas's first render loads the
-resources.
-
-## Rules
-
-**Before the first frame.** Only the start page and the Prepare tab's plater are built
-before the first frame. Everything else goes through a holder.
-
-**Reaching a lazy object.** Callers use the type's statics. Reading it if built is for
-things the object can live without, such as a rescale, a color change or a status refresh.
-Making sure it exists is for navigating to it or showing it. Running something once it is
-built is for state it would not fetch for itself on construction. A panel that pulls its
-state when constructed only ever needs to be read if built.
-
-**Unit size.** A unit should fit in one slice on a fast machine. A constructor over that is
-staged, and a single widget over it is accepted unless the widget itself can be split.
-
-**Order.** Tasks run cheapest and most likely to be opened first. Each holder's order is
-given where it is created, with gaps so a new task fits between its neighbors. A negative
-order is never prebuilt, for something few sessions open that costs more to build unasked
-than it saves.
-
-## Adopting it
-
-A lazy tab needs a panel type deriving from `LazyInstance`, a placeholder page the main
-window creates once with its order and registers for the idle build, and every use of the
-panel outside the main window going through the statics. Its constructor has to cope with
-the main window already existing and the user being busy elsewhere, so it takes no focus
-while off screen, and it does all of its own setup, since the main window does nothing to a
-panel after creating it.
-
-To stage a heavy constructor, keep the skeleton in the constructor, move the rest into
-steps in its original order, and follow the staged-construction constraints. Measure the
-units; a step that is still one big widget is split inside the widget or accepted.
-
-## Verifying
-
-The log lists the queue when it is registered, reports each completed task at info level
-and each slice and unit at debug level, and reports every on-demand build with its units

+# G-code preview while dragging
+
+The sliced preview draws every toolpath segment of the plate as an instanced box. On a large
+plate that is tens of millions of segments, and the frame is GPU-bound: the cost is the number of
+instances drawn, not anything the CPU does per frame. Dragging the camera over such a plate cannot
+keep up. The `preview_reduced_detail_mode` preference (*Graphics > G-code Preview*, off by
+default) lets the preview draw less while the user drags and put the full toolpaths back when they
+let go.
+
+| Preference | Values | Effect |
+|---|---|---|
+| `preview_reduced_detail_mode` | `off`, `solid`, `layers`, `outer_walls`, `shell` | what is drawn while dragging |
+| `preview_reduced_detail_layer_stride` | 1–20 | one layer in every N is kept by the toolpath modes |
+
+libvgcode (`src/libvgcode`) builds and binds the reduced toolpath set, `GCodeViewer` maps the
+preferences onto it and draws the solid model, and `GLCanvas3D` decides when the user is dragging.
+The OpenGL ES path keeps a single set and ignores the preference.
+
+## Two sets, one walk
+
+`ViewerImpl::update_enabled_entities()` walks the visible vertex range once and fills two segment
+index buffers side by side: the **full** set and the **reduced** set (segments and options).
+Building them together is what makes switching free: starting or ending a drag is a buffer
+binding, never a rebuild. A change of mode or stride does rebuild. Nothing is built while the mode
+is off, and the reduced buffers are then uploaded empty so that the last set does not stay
+allocated.
+
+Whatever the mode leaves out, the bottom and top layers of the visible range are kept whole: they
+are the faces the range cuts open, and the top is what the user is looking at.
+
+### Modes
+
+- `EndLayersOnly` (`solid` in the preference) keeps only the two end layers. `GCodeViewer` then
+  draws the sliced objects and the prime tower as opaque solids, see below.
+- `LayersOnly` (`layers`) keeps every role of one layer in every stride.
+- `OuterWallsOnly` (`outer_walls`) keeps the outer and overhang perimeters of one layer in every
+  stride. The prime tower and supports have other roles and are left out.
+- `ShellOnly` (`shell`) keeps what the shell extraction below marks as visible surface, of one
+  layer in every stride, plus whatever a view from above or below sees of the skipped layers, so
+  that a step does not vanish. It is the only mode that knows the prime tower's outside from its
+  inside.
+
+## The solid model
+
+The preview already loads the sliced objects as shells for its translucent ghost.
+`GCodeViewer::render_solid_model()` draws those shells opaque, in their filament colors, with the
+`gouraud` shader, whose z range cuts them to the visible layer range. The two toolpath layers of
+the reduced set are drawn afterwards and cap the cut with what was really printed there. The
+shells hold only the objects, so while this mode is on the prime tower is added from its sliced
+mesh, positioned as the print placed it. It is added or removed on its own when the mode changes,
+without reloading the objects, keeps its opaque color so that it never appears among the
+translucent shells, and stays out of their bounding box. Supports have no mesh and are not shown,
+and `load_shells()` drops every non-model-part volume, so a negative volume is not cut out.
+
+A plate whose shells are not loaded keeps drawing toolpaths, since the solid model would leave
+only the end layers.
+
+## Shell extraction
+
+`ViewerImpl::update_shell_bitset()` classifies every extrusion segment once per load, on demand
+the first time the shell mode needs it, and records the result in four bit sets. It is purely
+geometric so that the wipe tower, whose every segment shares one role, works as well as the
+objects.
+
+Each layer is rasterized into a coarse 2D **occupancy grid** over the print's footprint: cells
+are 0.5 mm, or coarser so that the grid is at most 1024 cells across. The footprint is then
+**closed** with a radius of 2.5 mm so that sparse infill and support read as the solid area they
+belong to, while holes wider than 5 mm stay open. The closing dilates each 8-connected component
+separately and leaves a cell that two components both reach empty, so the gap between two objects
+standing close together is never bridged and both of their facing walls stay on the shell;
+fragments under eight cells do not spread and are absorbed by whatever reaches them. A separable
+erosion shrinks the result back, and the raw cells are OR-ed in again so that a closing never
+loses one.
+
+A cell is a **shell cell** when it is filled and any of its six neighbours, four in the layer,
+one below, one above, is not. A segment is on the shell when at least half of the cells it
+crosses are shell cells: walls run along the shell, infill only touches it at the ends. The
+interior infill roles and gap fill are excluded regardless, since short infill segments hugging a
+wall would otherwise pass by the thousand.
+
+Two refinements keep sloped surfaces closed:
+
+- **Near-wall segments.** The step between one layer's outer wall and the next is often
+  narrower than a cell. An inner wall (`Perimeter`) segment whose midpoint lies within a line and
+  a half of an outer or overhang perimeter of the same layer is kept as well. So is any segment,
+  whatever its role, whose midpoint lies within that reach, or a cell if larger, of an outer wall
+  of the layer above or below: that strip is the exposed band of the step, which the cell tests
+  cannot see when it is narrower than a cell.
+- **Top and bottom visibility.** The same pass records the highest and lowest layer occupying
+  each cell over the whole print. A segment whose layer is the topmost occupant of any cell it
+  crosses is visible from above, and likewise from below with the lowest. These segments are kept
+  even when their layer is skipped by the stride.
+
+The layer range is split across up to eight `std::async` workers, each owning its grids. An
+allocation failure on a huge print falls back to marking every segment as shell, which leaves out
+only the hidden infill roles.
+
+## Deciding that the user is dragging
+
+`GLCanvas3D::_update_preview_interaction()` runs at the top of every preview frame, before the
+canvas decides whether to reuse its cached scene, so that the switch lands in that frame. Dragging
+is `GLCanvas3D::is_user_interacting()`, the same answer the scene cache reads: the camera, the
+navigator, a gizmo, the rectangle selection or either slider being held. A slider reports this from
+ImGui's active id rather than its dirty flag, which is raised and consumed inside one frame. A
+wheel step has no duration, so it holds the reduced set for a 150 ms settle time instead, and the
+frame that restores the toolpaths is scheduled for when that time runs out, since the render timer
+only wakes the idle loop. A drag cut short by focus or capture loss is ended explicitly, and a
+button release wakes the idle loop, because on some platforms nothing else would until the next
+input.
+
+## Reused scene frames
+
+`GLCanvas3D` keeps its last scene pass for frames that only rebuild the overlay (`SceneCache`). Its
+key covers the canvas size, the camera and hover state, not what the toolpath sets draw, so a frame
+that reuses the scene must never be one on which the set is switched.
+`_update_preview_interaction()` therefore reports whether the bound set changed, and a frame on
+which it did redraws the scene. The canvas neither captures nor reuses the scene while the user
+drags, so no reduced frame outlives a drag, and the frame that ends a wheel's settle time is
+requested as a full frame.

-# Multiline infill — High Level Design
-
-## Purpose and scope
-
-`fill_multiline` prints every sparse infill wall as N adjacent lines instead of
-one, so a wall is `d1 = N * spacing` thick. Only internal sparse infill uses it.
-Each pattern first builds its single-line centerlines at N times the usual line
-spacing (so the density holds), and `multiline_fill()` then replaces each
-centerline by the lines of that wall: the centerline itself when N is odd, and
-closed outlines around it at every `spacing` out to `d1 / 2`. The outlines are
-clipped to the fill region contracted by half a line width, then connected like
-any other infill.
-
-Outlines of centerlines that cross each other overlap at every crossing, which
-over-extrudes the wall intersections. The line-crossing patterns Grid,
-Triangles, Tri-hexagon and Cubic therefore build centerlines that never cross
-(`FillRectilinear::fill_surface_trapezoidal()`), and so do Adaptive Cubic and
-Support Cubic (`FillAdaptive`); the other patterns outline their usual
-centerlines.
-
-## Non-crossing centerlines
-
-The crossing lines are resolved into x-monotone paths, the levels of the line
-arrangement: walking along x, the k-th path is always the k-th line from the
-bottom. At every crossing, the two paths bounce off each other instead of
-passing through. Adjacent paths meet only at crossings, so their outlines touch
-there and nowhere overlap.
-
-Where two paths meet, each is cut short by a line perpendicular to the bisector
-of its bend, `d1 / 2` from the crossing. The two cut segments are parallel and
-`d1` apart, so the outermost lines of the two walls sit exactly `spacing` apart,
-like the lines inside a wall. Where three lines meet at one point, the middle
-path runs straight through and the outer two are cut `d1` from it.
-
-Each pattern builds its rows along x in a rotated frame. Grid lines run at ±45°
-there, and its rows are trapezoid waves that transpose on alternate layers. The three families of Triangles, Tri-hexagon and
-Cubic run at 0°, 60° and 120°. Those rows rotate by 120° every layer about a
-3-fold center of the arrangement, so each family takes every role in turn.
-The pattern is phased on fixed positions, so it lines up across layers and
-across the regions of one layer. Rounding the corners with
-`sparse_infill_smooth_factor` happens before `multiline_fill()`.
-
-## Cubic
-
-Single-line Cubic draws the three families at the same spacing `h` and shifts
-them with z: by `+dx`, `-dx` and `+dx`, `dx = z / sqrt(2)`. The multiline paths
-follow the same lines. In the frame where one family is horizontal, the other two
-cross in rows `h` apart, alternating by half a period, at height
-`tau = -3 * dx (mod h)` above the horizontal line below them. The crossings split
-every band between horizontal lines into up-pointing triangles of height `tau`,
-down-pointing triangles of height `h - tau`, and hexagons. At `tau = 0` (and `h`)
-all three families meet at common points, as in Triangles. At `tau = h / 2` the
-triangles are equal, as in Tri-hexagon. The origin of that frame is always a
-3-fold center, whatever z is, so the per-layer rotation keeps the lines in place.
-
-Each band holds two paths that touch at its crossings: the upper one takes the
-V below the crossing and runs along the top horizontal line, and the lower one
-takes the inverted V above it and runs along the bottom line. Both are the same function
-of `tau`, the lower one mirrored with `h - tau`. `cubic_upper_level()` builds one
-period of the upper path as the lower envelope of five lines, clipped from below:
-
- the two slanted lines through the crossings,
- the horizontal line, lowered when the triangle above it is less than `1.5 * d1` high,
- the two chamfers where the path turns onto and off the horizontal line, `d1 / 2`
-  from those crossings,
- the flat cut into the V at the crossing.
-
-The cut height `clamp(tau - d1 / 2, 0, h - d1) + d1` is what makes the pattern
-continuous in z. While both triangles are at least `1.5 * d1` high, every
-crossing is a pair of bends `d1 / 2` from it, as in Tri-hexagon. When a triangle
-is thinner, its three paths stack like a triple crossing. The path through it
-flattens toward its base line and lies on it once the triangle is under `d1 / 2`
-high, and the paths beside it are pushed `d1` away. The layout thus reaches the
-Triangles one where the families meet. Adjacent paths stay at least `d1` apart
-at every `tau` and at every density up to 100%.
-
-## Adaptive Cubic
-
-Adaptive Cubic and Support Cubic take their lines from an octree of cubes
-standing on a corner. On each layer every cube cuts its three mid-planes into
-segments of the same three 60° families as Cubic, but the pattern is not
-periodic. Smaller cubes near the surface add finer lines, and a finer line ends
-where it meets the wall of its coarser cube, so the lines form crossings and
-T-junctions. `FillAdaptive::multiline_paths()` builds the paths from these
-segments directly, for each fill region and within `4 * d1` of it.
-
-At a crossing the two paths bounce as in Cubic. At a T-junction the through line
-runs straight on and the path of the ending line stops there. Every path still
-runs left to right in the frame where one family is horizontal, and that family
-rotates with the layer.
-
-Every line of every cube size lies on one fine lattice, so crossings closer than
-a few `d1` are the corners of one small triangle of that lattice, as in Cubic.
-The cuts follow the Cubic rules without a closed formula:
-
- The two bends of a crossing are cut `d1` apart, `d1 / 2` each, perpendicular
-  to their bisector, so their walls touch. A cut goes no further than the path
-  end, and the other bend takes the rest of `d1`.
- At the tip of a small triangle, between the two slanted families, a cut also
-  goes no further than the neighbouring bend turning the other way, and the
-  path beyond that bend is kept a wall away from it. The bends onto the
-  horizontal family are not limited this way: pushing their paths apart would
-  open gaps between walls that should touch.
- A cut moves the path only where the cut line lies beyond it, near its bend.
-  The sharp bends between the two slanted families are cut after the bends onto
-  the horizontal family, so the tip of a small triangle wins, as in Cubic.
- A path stopping at a T-junction is trimmed until it is `d1` less half a line
-  spacing from every other path, so that its end overlaps the wall it stops on
-  by half a line and bonds to it. The paths are trimmed one at a time against
-  the others as already trimmed, so two ends facing each other meet instead of
-  both backing off. A path stopping on the line of another is trimmed before
-  that one, so it gives way and the other still reaches the line it stops on. A
-  second round trims every path again from its full length, so an end grows
-  back where the ends it gave way to were trimmed later, and a last round only
-  shortens them, keeping them that far apart. Paths shorter than `d1` are left
-  out.
- A line that ends on another less than `2 * d1` past a crossing stops at that
-  crossing instead, the shorter one where both do. The path along such a stub
-  would be trimmed away, leaving a hole between the walls that were cut to
-  touch it.
-
-Short paths enclosed by coarser lines still print as closed outlines, but most
-paths run on across several cells.

-# Prime tower sparse layers — High Level Design
-
-## Purpose and scope
-
-A prime tower exists to absorb filament changes, but it is planned on every
-object layer below the topmost change, not only on the layers that purge. The
-layers in between carry no filament change and print nothing but a block of the
-tower's own footprint to keep its top level. They are called sparse layers, and
-on a print with few changes they are most of the tower: they cost time, filament
-and a travel to the tower on every layer.
-
-Two settings trade that cost against something else. `wipe_tower_no_sparse_layers`
-drops them, which sinks the tower below the model. `wipe_tower_sparse_layers_combination`
-merges runs of them into fewer, thicker layers, which keeps the tower level with
-the model. Both are off by default, and with both off the tower prints one layer
-per object layer as it always has.
-
-The decisions belong to tower planning and G-code emission. They do not change
-sliced object geometry, but they do change the emitted G-code, the filament and
-time estimates, and — for the compacted case — whether a plate is printable at
-all. Changing either setting invalidates the tower step.
-
-## What a sparse layer is
-
-`ToolOrdering::fill_wipe_tower_partitions` counts the filament changes per layer
-and propagates that count downwards, so every layer below the topmost change is
-marked as carrying a tower. It then fills any gap between two tower layers, so
-the tower is continuous from the bed to its last purge. `wipe_tower_layer_height`
-is the distance from the previous tower layer, which is the object's layer height
-whenever the tower prints on every layer.
-
-`Print::_make_wipe_tower` plans one tower layer per such object layer. A layer
-whose only call keeps the current filament leaves no toolchange in the plan, and
-the layer it generates is a single result whose initial and new tool are equal.
-That is what `wipe_tower_layer_is_sparse` recognises, and it is the unit both
-settings work on.
-
-The plan stays one entry per tower layer in every case. The G-code emitter walks
-`WipeTowerData::tool_changes` by layer index, advancing once per object layer
-that carries a tower, so a planner that removed entries would silently shift
-every later layer onto the wrong tower geometry. Layers that print nothing are
-therefore still planned and still generated; they are marked, and the emitter
-drops them.
-
-## Shared rules
-
-Tower planning, G-code emission and the plate validation all have to agree about
-which layers print and where. They ask one set of free functions, declared beside
-the tower classes, rather than each re-deriving the answer from the raw options:
-
- `wipe_tower_sparse_layers_skipped` — whether sparse layers are really dropped.
-  Smooth timelapse and clumping detection park the nozzle on the tower every
-  layer, so with either of them on no layer is ever dropped and the option reads
-  as off everywhere.
- `wipe_tower_sparse_layers_combined` — whether runs are really merged. The same
-  two rule it out, and so does `wipe_tower_no_sparse_layers`: dropping the layers
-  outright is the stronger answer to the same problem, so the two settings are
-  exclusive and the GUI greys out the second while the first is on.
- `wipe_tower_layer_is_sparse`, `wipe_tower_layer_is_combined_away` — per-layer
-  questions the emitter asks about generated results.
- `compute_compacted_wipe_tower_z` — the tower's print z per planned layer when
-  it is compacted.
- `combine_sparse_wipe_tower_layers` and its `combine_sparse_wipe_tower_plan`
-  wrapper — the merge rule, applied to either generator's plan.
-
-Both tower generators are driven through these. `WipeTower` (Type 1, the block
-tower) and `WipeTower2` (Type 2, the default) keep separate plans with the same
-per-layer shape — print z, layer height, toolchanges, and a `combined_away` flag
-— so one template covers both.
-
-## Dropping sparse layers
-
-With `wipe_tower_no_sparse_layers`, the tower only grows on layers that carry a
-real change. It therefore falls one layer height behind the object for every
-sparse layer, and by the top of a tall print it can sit far below the model. The
-nozzle has to reach down to it at each purge.
-
-`compute_compacted_wipe_tower_z` derives that z once, from the generated results,
-so the emitter and the validator cannot disagree. Emission descends to it, but
-only once the nozzle is parked over the tower: descending while still over the
-model would drive the nozzle into the print, so a descent that would do that is
-deferred until after the travel to the tower. Extrusions emitted without an
-explicit z — the nozzle-change wipe in particular — are pulled down to the
-compacted z for the same reason.
-
-Reaching down is only safe if nothing tall stands near the tower. `Print.hpp`
-carries the clearance rule: a keep-out zone grown from the tower's footprint by
-the spiral z-hop envelope, and a per-object limit on how high an object may rise
-near it, tiered by the nozzle cone, the head body, the rod and the lid. The same
-rule serves the precise check on real extrusions, the pre-slice estimate that
-feeds the plater, and the outlines the plater draws while an object is dragged,
-so that the ring the user sees touches the object's outline exactly when the
-check trips.
-
-## Merging sparse layers
-
-With `wipe_tower_sparse_layers_combination`, no layer is dropped and nothing is
-compacted: the tower keeps following the object, and the nozzle never descends.
-Instead a run of consecutive sparse layers prints once, on the run's last layer,
-at the accumulated height of everything it covers — the same way infill
-combination merges sparse infill. The layers below it in the run print nothing.
-
-`combine_sparse_wipe_tower_plan` runs before the tower's depths are planned,
-because the heights it rewrites feed the extrusion flow of every later pass. It
-raises `height` in place on the layer that prints a run and sets `combined_away`
-on the rest; generation then proceeds unchanged, and the flag is copied onto the
-results so the emitter can drop them.
-
-Four constraints shape the rule:
-
- **Whole layers only.** A tower layer is entered at the object's z, so a merged
-  layer has to end on an object layer boundary. The merged height is therefore a
-  sum of whole layer heights, never a clamped value.
- **The nozzle's maximum layer height.** A run stops growing as soon as one more
-  layer would pass `max_layer_height` for the nozzle printing it — three quarters
-  of the nozzle diameter when that is left at 0, as elsewhere in slicing. The cap
-  is read through the filament-to-nozzle map, since `max_layer_height` is per
-  nozzle while the tower indexes filaments. This is what makes the setting inert
-  at common layer heights: two 0.2 mm layers are 0.4 mm and do not fit under a
-  0.3 mm maximum, so nothing merges until the layer height is 0.15 mm or below,
-  or the maximum is raised.
- **A filament change purges at its own z.** A layer with a real change can
-  neither be merged away nor absorb the run below it, so a run always ends on its
-  own last sparse layer and the change above it is untouched.
- **The first layer stays on the bed.** It carries the brim and is never merged.
-
-A run holds one filament throughout — that is what makes it sparse — so the cap
-is uniform across it, and the tower reserves depth only for the purges above a
-layer, so a run has one footprint and the merged layer covers exactly the area
-the layers it replaces would have.
-
-## Emission and accounting
-
-`WipeTowerIntegration` drops a layer whose results are marked, for both settings,
-through the same `ignore_sparse` path in `tool_change` and
-`is_empty_wipe_tower_gcode`. A dropped layer emits no travel to the tower and no
-extrusion.
-
-Filament used is accumulated by the generators while they write, so a layer that
-will be dropped must not be charged. Type 1 asks `layer_is_printed` at each of
-its accumulation points; Type 2 guards the equivalent block in `finish_layer`,
-which also stops a merged-away layer from adding height of its own — the layer
-that prints the run carries all of it.
-
-A merged layer is the only case where the tower's layer height differs from the
-object layer it sits on, and therefore the only case where the height the
-exporter already emitted for that layer is wrong for the tower. Both generators
-do declare a height, but each hardcodes a tag dialect — the block tower forces
-the BBL tag, the other writes the compatible one — while the G-code processor
-reads only the tag its printer uses. On a non-BBL printer with a Type 1 tower the
-declaration is dropped, and the merged layer is drawn and costed as a thin one.
-`WipeTowerIntegration::tower_height_tag` therefore declares it at export time,
-where the printer is known, and only when the tower's own G-code does not already
-carry the tag that will be read. The object's height returns on the next object
-path, because emission forces the processor role to the tower on any layer that
-carries one.
-
-## Constraints
-
-A layer that prints nothing prints nothing at all, including any interface work
-the tower planner scheduled there. The Type 1 block planner marks a layer as a
-contact layer when a filament category stops or starts being used relative to the
-layer below, and a sparse layer immediately above a change qualifies. Merging a
-run, like dropping its layers, replaces that interface with the run's single
-layer. Both settings are off by default for this among other reasons.
-
-Neither setting changes what the tower is for. A plate that needs a tower on
-every layer — smooth timelapse, clumping detection — gets one, and the settings
-read as off rather than compacting or merging in one place and not another.

-  both settings, the per-layer predicates, the compacted z, the merge rule's run
-  flushing, height conservation, the nozzle cap and the first-layer exemption,
-  and the clearance geometry the plater draws.
- [Slicing tests](../../tests/fff_print/test_wipe_tower.cpp) slice a real print
-  and check that a run folds, that the tower still covers the object exactly
-  once, that a run too thin for the cap is left alone, and that a merged layer
-  declares its height in the tag the printer's processor reads.

Hanif Koh	8b2ae48e4a	Keep the Exposed Band of a Sub-Cell Step Beside the Neighbouring Layer's Outer Wall On a shallow surface the band of a layer that the layer above leaves exposed is narrower than a grid cell, so whether the layer is the topmost occupant of any cell flickers from layer to layer and the band's segments, inner walls and solid infill hidden by role, came and went in a dashed ring. That band is always in the same place: the strip just outside the outer wall of the layer above, or of the layer below for the underside of an overhang. The classifier now keeps the outer-wall cell map of the previous and next layers as well as the current one, rotating like the footprints, and keeps any segment whose midpoint lies within a line and a half, or a cell if larger, of a neighbouring layer's outer wall. It can only add segments, so no hole is opened by it; what it over-keeps is the covered strip under the neighbour's wall.	2026-09-23 12:53:58 +08:00
Hanif Koh	8095904bc2	Catch Only Allocation and Thread Failures Around the Shell Classification The fallback that marks every segment as shell caught everything, which would also have hidden a logic error. It now catches what the classification can really throw on a huge print: std::bad_alloc from its grids and std::system_error from a worker thread that cannot be launched.	2026-09-23 12:34:56 +08:00
Hanif Koh	b7c86befe1	Keep the Surfaces the Roles Name in the Shell-Only Drag Mode The shell test asks whether at least half of the cells a segment crosses lie on the footprint's boundary. On a curved wall the boundary is a staircase of cells, and an outer-wall segment that runs past an inside corner of that staircase crosses cells whose four neighbours are all filled, so a short segment there failed the test and vanished, leaving a hole with the inner wall showing through it. A shallow dome does the same to its top skin: one layer's ring lies within the same cells as the next layer's, so it is neither a boundary nor the topmost occupant, and the bridges under it showed through. Outer walls and the top and bottom skins are the surface by definition, so the mode now keeps them whatever the grid says, and the grid decides only for the roles that can be either: inner walls, the prime tower, supports, skirt and brim.	2026-09-23 12:34:56 +08:00
Hanif Koh	526a91d323	Add a Shell-Only Drag Mode That Keeps the Visible Surface of the Print Outer walls is a role filter, which loses the prime tower, whose every segment shares one role, and every top and bottom surface between the range's ends. A fifth mode, Shell only, keeps what a geometric classification marks as the visible surface of the print, of one layer in every N, plus whatever a view from straight above or below sees of the layers it skips, so that a step does not vanish. The classification runs once per load, the first time the mode is needed, and is purely geometric: each layer is rasterized into a half-millimetre occupancy grid and closed so that sparse infill reads as solid, a cell is on the shell when any of its six neighbours is empty, and a segment is kept when at least half of the cells it crosses are. The closing dilates each connected component on its own and leaves a cell two components reach empty, so the gap between two close objects is never bridged. The first inner wall beside an outer wall is kept as well, since the step of a sloped surface is narrower than a cell, and the interior infill roles and gap fill are never taken, whatever the geometry says. The layers are split across up to eight workers, and an allocation failure on a huge print falls back to keeping everything but the hidden infill. Separate from the other modes so that it can be dropped on its own.	2026-09-23 12:14:16 +08:00
Hanif Koh	493896260e	Let the User Choose What the Preview Draws While Dragging The solid model is one answer to a preview that cannot keep up with a drag; a reviewer asked for the two that keep the drag view made of toolpaths. The checkbox is now a combobox, "Simplify preview while dragging", with Off, Solid model, Skip layers and Outer walls, and a spin, "Draw one layer in every N", for the toolpath modes. Off is the default, and with it nothing is built. Skip layers keeps one layer in every N. Outer walls keeps the outer and overhang perimeters of those layers, so the prime tower and supports, whose segments have other roles, drop out of it. Both keep the bottom and top layers of the visible range whole, as the solid model does, so the faces the range cuts open stay what was printed there. libvgcode takes the choice as EReducedDetailMode and a stride; the sets are rebuilt when either changes, and drawing from the reduced one is still a buffer binding. A mode change reaches the loaded preview at once, as the checkbox did.	2026-09-23 12:14:16 +08:00
Hanif Koh	ca83497bb6	Release the Reduced Set When Unused and Share the Drag Check With the Scene Cache The reduced index buffers were only re-uploaded while the preference was on, so the last set stayed allocated until the next load once it was switched off, and their size was missing from get_used_gpu_memory(). They are now uploaded on every rebuild, empty when nothing was built, and counted. The scene cache and the solid model both asked whether the user was dragging, with different lists: the cache knew about gizmos and the rectangle selection, the solid model about the navigator and the sliders. One is_user_interacting() now answers both. The tooltip says that negative volumes are not cut out of the solid model, since load_shells() drops every non-model-part volume, and the preferences handler keeps the dimming comment with the branch it documents.	2026-09-23 12:13:49 +08:00
Hanif Koh	6a985744c4	Offer the Sliced Objects as a Solid Model While Dragging The G-code preview draws every toolpath segment as an instanced box, and its frame cost is linear in the number of segments drawn. On a plate of large objects that is enough that dragging the camera or a preview slider cannot keep up, and no amount of per-segment work changes that; only drawing fewer segments does. The objects themselves are cheaper: a mesh costs its triangles once, however many layers it has, and the preview already loads the objects as shells for its translucent ghost. A new preference, "Only render solid model when dragging" (off by default), draws those shells opaque in their filament colours instead of the toolpaths while the user drags. The visible layer range still holds. The shells are cut at the range's top and bottom through the gouraud shader's z range, and libvgcode keeps a second index buffer holding just the range's bottom and top layers, filled in the same walk as the full one, which is drawn afterwards so that it caps the cut with what was really printed there. Switching between the two sets is a buffer binding, never a rebuild. The prime tower is added to the shells from its sliced mesh while the preference is on, positioned as the print placed it; it keeps its opaque colour and so stays out of the translucent ghost. Supports have no mesh and are not shown. Dragging is the camera, the navigator or either slider being held; a slider reports it from ImGui's active id, since its dirty flag is raised and consumed inside one frame. A wheel step holds the solid model for a 150 ms settle time, with the frame that restores the toolpaths scheduled for when it runs out. The switch is decided at the top of the frame, before the cached scene is consulted, and a frame that switches redraws the scene. A drag cut short by focus or capture loss is ended explicitly, and a button release wakes the idle loop, since on some platforms no idle event follows it until the next input. With the preference off, nothing is built and the preview is unchanged.	2026-09-23 12:13:49 +08:00
