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.

+# 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.

-# Printer agents
-
-Printer agents isolate printer-specific communication from the rest of OrcaSlicer. The GUI and
-`DeviceManager` operate on a shared set of printer operations and device state; a selected printer
-agent implements those operations for a particular printer ecosystem. The agent boundary allows
-Bambu, Moonraker-based printers, built-in integrations, and Python-provided integrations to use the
-same application workflow without making the GUI understand every printer protocol.
-
-The current boundary is an adapter boundary around the existing application contract. In particular,
-some request fields and message payloads still use the Bambu-shaped representation that existing
-`MachineObject` and `DeviceManager` code consumes. The printer agent is responsible for translating
-that representation into the protocol spoken by its printer. This is an intentional compatibility
-constraint of the current design; the interface is not yet a neutral printer protocol.
-
-The v1 dialect migration path is deliberately narrow. `DeviceManager` currently speaks the Bambu JSON
-dialect because that is the payload shape already used throughout the command and state workflow. The
-v1 `OrcaPrinterAgent` also accepts that Bambu dialect. Its transport path places the small translation
-needed for the target printer at `deliver_to_sink`, keeping the compatibility code at the edge rather
-than spreading it through `DeviceManager` or the agent interface.
-
-The eventual direction is for `DeviceManager` to produce an Orca JSON dialect. The Bambu agent will then
-own the translation from Orca JSON to Bambu's protocol, while `OrcaPrinterAgent` can forward the Orca
-payload directly to its sink. The v1 translation at `deliver_to_sink` can then be removed without
-changing `DeviceManager`, the command callers, or the rest of the agent workflow.
-
-## Components
-
-The system has four relevant layers:
-
-```text
-GUI / DeviceManager / MachineObject
-              |
-        NetworkAgent
-          /       \
- IPrinterAgent   ICloudServiceAgent
-      |                 |
- printer protocol   authentication and cloud services
-```
-
-### `DeviceManager` and `MachineObject`
-
-`DeviceManager` owns the application-facing printer workflow. It maintains `MachineObject` instances,
-updates their state, filters devices for the active printer agent, and initiates operations such as
-homing, temperature changes, printing, subscriptions, and camera playback.
-
-`MachineObject` remains the shared state model used by the GUI. It does not contain the implementation
-of a printer protocol. When a device is discovered or returned by a cloud query, the device is tagged
-with the active `printer_agent_id`. Device lists and selected-machine operations use that tag to avoid
-sending an operation through an agent that does not own the device.
-
-### `NetworkAgent`
-
-`NetworkAgent` is the façade used by the GUI and `DeviceManager`. It owns:
-
- the currently selected `IPrinterAgent`;
- the registered cloud-service instances, indexed by provider;
- callbacks shared by the active printer agent and the application;
- the forwarding methods for printer commands and cloud operations.
-
-There is one active printer agent for the currently selected printer preset. Switching the preset
-increments the machine-list generation, disconnects the old printer agent, removes its callbacks, and
-installs the newly selected agent. The façade then forwards printer operations to that agent.
-
-Cloud operations are selected separately using a provider key. `NetworkAgent` forwards a cloud request
-to the matching `ICloudServiceAgent`, and forwards cloud camera operations with a device ID. The
-printer agent receives a cloud-agent pointer through `set_cloud_agent()` when it is created, allowing
-printer communication to obtain cloud tokens without depending on a concrete cloud implementation.
-
-### `IPrinterAgent`
-
-`IPrinterAgent` is the printer-facing contract. It covers:
-
- cloud-relay and direct-LAN message delivery;
- LAN connection, discovery, binding, and certificates;
- printer subscriptions and callbacks;
- print operations;
- filament synchronization;
- camera capability and local camera URL reporting;
- printer command methods.
-
-Concrete built-in implementations include the Bambu wrapper, the native Orca/Moonraker path, and
-other printer-agent implementations registered by the application. A printer agent may use either
-the cloud agent, a direct LAN connection, or both.
-
-### `ICloudServiceAgent`
-
-`ICloudServiceAgent` owns authentication and services provided by a cloud backend. It covers login
-state, tokens, user and printer lists, settings synchronization, model services, cloud messages, and
-cloud camera operations.
-
-Cloud camera operations are device-scoped:
-
- `get_camera_url(dev_id, callback)` obtains a stream URL for one device;
- `create_camera_signaling_channel(dev_id)` creates signaling for one device where the provider
-  supports it.
-
-This is separate from the local camera URL exposed by `IPrinterAgent`, which is currently scoped to
-the active printer agent because a normal LAN agent represents one physical printer connection.
-
-## Agent registration and selection
-
-`NetworkAgentFactory` maintains the printer-agent registry. Each registry entry contains an agent ID,
-a display name, and a factory function. Built-in agents register during application initialization.
-Python printer-agent capabilities register dynamically and contribute an agent ID and factory entry.
-
-The selected printer preset contains the printer-agent choice. If no explicit choice is stored, the
-application preserves the existing default behavior: Bambu presets select the Bambu agent and other
-presets select the native Orca agent. When a preset is changed, `GUI_App` resolves the effective agent
-ID, obtains the corresponding cloud agent, creates the printer agent through the registry, and installs
-it in `NetworkAgent`.
-
-The registry rejects conflicting agent IDs. This matters for Python plugins because an agent ID is the
-stable identity used by presets and device ownership; two enabled plugin capabilities must not claim
-the same ID.
-
-## Message and command flow
-
-There are two low-level message paths:
-
- `send_message()` publishes a command through the printer's cloud relay;
- `send_message_to_printer()` sends a command directly to the printer over the LAN path.
-
-Both paths accept a JSON string, quality-of-service and flag values, and return the existing network
-status code domain. The agent owns the conversion from that JSON contract to its native transport.
-
-The typed `command_*` methods are the application-facing convenience layer. The five generic defaults
-currently implemented by `IPrinterAgent` construct the existing JSON dialect and route through the
-same message path:
-
-| Method | Default operation |
-| --- | --- |
-| `command_xyz_abs()` | Send `G90` for absolute positioning |
-| `command_auto_leveling()` | Send `G29` for bed leveling |
-| `command_go_home()` | Use the supported homing operation or send `G28` |
-| `command_set_bed()` | Use the supported bed control or send `M140` |
-| `command_set_nozzle()` | Send `M104` for nozzle temperature |
-
-These are compatibility defaults for common printer workflows, not a guarantee that every firmware
-implements every command identically. An agent can override a method when its protocol needs another
-operation. For example, a Klipper configuration may use `BED_MESH_CALIBRATE` instead of `G29`.
-
-The remaining common command methods default to `ORCA_NETWORK_ERR_CMD_NOT_SUPPORTED` because their
-existing behavior is vendor-specific or has no portable implementation:
-
- AMS RFID refresh;
- AMS calibration;
- AMS tray selection;
- camera start;
- axis control.
-
-The methods remain on the common interface so an agent that supports them can override them explicitly.
-`sequence_id` remains part of the command contract because `DeviceManager` creates and tracks it as
-the command ID.
-
-## Device ownership and stale responses
-
-Printer-agent ownership is represented by `printer_agent_id` on device records and `MachineObject`
-instances. The active agent ID is attached when a device is discovered, returned by a cloud list, or
-reused after a preset switch. Local-machine configuration also persists the agent ID so a saved LAN
-device is not silently reused by an unrelated agent.
-
-Cloud printer-list responses carry three pieces of request context added by `NetworkAgent`:
-
-```text
-provider   cloud provider used for the request
-agent_id   active printer agent when the request was made
-generation machine-list generation when the request was made
-```
-
-`DeviceManager` accepts the response only when those values still match the current provider, active
-agent, and generation. This prevents a slow response from the previous preset or provider from
-repopulating the current device list.
-
-The provider mapping is currently selected by `GUI_App`: the Bambu agent maps to the Bambu cloud
-provider and other agents map to the Orca cloud provider. The generation check protects that existing
-selection from races; it does not make cloud-provider ownership intrinsic to an agent. Cloud-printer
-ownership and the broader Orca cloud services are therefore still separate architectural concerns.
-
-## Python printer agents
-
-`PrinterAgentPluginCapability` implements `IPrinterAgent` directly. The live capability object is
-registered with `NetworkAgentFactory` and handed out as the printer agent when its agent ID is selected.
-The plugin receives the selected `ICloudServiceAgent` through `set_cloud_agent()` just like a built-in
-printer agent.
-
-Python plugins must implement the core communication and lifecycle methods required by the interface,
-including agent metadata, printer connection, discovery callbacks, and the two message-send methods.
-Methods that are meaningful only to a particular printer are optional overrides where the C++ base
-class provides a default.
-
-All ten `command_*` methods are available in the Python binding and in the trampoline. Their override
-status is intentionally optional:
-
- the five generic commands use the C++ default when Python does not override them;
- the five vendor-specific commands return `NOT_SUPPORTED` unless Python supplies an implementation;
- a Python implementation can replace either behavior for its own protocol.
-
-The Python camera binding exposes HTTP, HTTPS, RTSP, and HTTP-snapshot modes. WebRTC remains a
-built-in C++ camera mode, but is not exposed as a Python mode because the current Python capability
-does not provide the corresponding cloud signaling-channel contract.
-
-## Camera playback boundary
-
-The camera stream mode describes how a stream is obtained; it does not by itself define ownership of
-the wxWidgets view that renders it. `MediaPlayCtrl` selects and tears down the active backend, while
-the wx parent owns the child window or renderer. This is important because a web view, native media
-control, and frame-based/WebRTC renderer have different wx window-lifetime requirements.
-
-Cloud URL and signaling requests are routed through `NetworkAgent` to the cloud provider selected for
-the device. Local URL requests are routed to the active printer agent. The distinction keeps cloud
-account services device-scoped while preserving the current one-LAN-agent/one-printer model.
-
-## Compatibility constraints
-
-The printer-agent boundary intentionally preserves several existing application contracts:
-
- Bambu-shaped JSON is still the shared command representation;
- existing network status codes are reused, with Orca-specific unsupported/capability errors added
-  in the Orca-reserved range;
- `MachineObject` remains the shared device-state model;
- preset and local-machine data retain compatibility with the existing agent-selection behavior;
- Python plugins use the existing capability and pybind11 registration system.
-
-The agent abstraction is therefore responsible for containing vendor differences, not for pretending
-that all vendor protocols are identical. The planned Orca JSON dialect is the protocol-neutral command
-model for the `DeviceManager`/agent boundary. Once it is introduced, Bambu-specific translation remains
-inside the Bambu agent and the Orca agent's v1 sink adapter can be removed as a self-contained cleanup.

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
