Collecting every candidate within the radius into a vector cost more
than the search itself. Same order, so the seams are unchanged;
align_seam_points ~19.6 s at 0.1 mm / 2000k, was ~21.
detect_surfaces_type, process_external_surfaces and the vertical shells
each waited on their own heaviest layer in turn. The LOTR map plate
slices in ~10.5 min at 0.1 mm / 2000k, was ~11.5; ~87 s at normal
settings, was ~97.
MultiPoint had no rvalue constructor, so the derived move constructors
bound to the const reference and copied; append reserved exactly, so
collecting pieces one by one was quadratic. Colour segmentation ~3 s at
0.1 mm / 2000k, was ~40, and ordinary prints gain too.
Only the slices within the deepest shell offset decide the result, so
the work is done per tile of the face. Top and bottom segmentation
~130 s at 0.1 mm / 2000k, was ~180.
ClipperLib slows down with the number of edges on a scan line, and a
layer cut through a fine relief has tens of thousands of pieces.
detect_surfaces_type ~50 s at 0.1 mm / 2000k, was ~145.
The merge took anything from 3 to 38 minutes at 0.1 mm / 2000k, now
~2.5. Every region is grouped with the islands it overlaps, so the
result is the same.
A colour texture baked at 0.1 mm / 2000k made the top layers thousands
of islands and slicing never finished. Colour segmentation runs per
island, the merge subtracts piece by piece, the support check tests only
nearby islands, and the travel ordering finds crossings through a grid.
A layer split into ~1000 colour fragments (a colour texture baked over a
large top face) made several per-fragment loops redo whole-layer ClipperLib
work, so slicing took ~33 min; it now takes ~3 min with the same output.
- make_fills: clip the layer's no-overlap area to each expolygon's box
before intersecting
- discover_vertical_shells: small-piece filter compares only against the
nearby part of the layer
- bridge_over_infill: whole-layer union/diff/intersections restricted to the
candidate's neighbourhood; fill boundary expanded once per spacing; anchor
tree built only from lines crossing the scan range; bbox pre-check in the
collision test; limiting outline taken directly instead of through
expand(..., 0.3 * flow.spacing()), which offsets by 0.135 scaled units
(flow.spacing() is in mm) and only cost a whole-layer pass per candidate
- Bake job: include GUI.hpp for show_error()
- Texture panel: select/erase whole model next to the paint tools, brush
size slider back on the same row
- Bake: each layer is sampled only on its own painted area; analytic
projections used to stack every layer over every painted region, so the
top layer's texture showed on all of them (colour sampler too)
- Auto resolution follows the texture's texel size and sharpness again
- Unwrap: charts cut by each face's own normal (a cube gives 6 islands, not
12 triangles); non-disk charts (tubes, closed shells) are split until they
flatten; connected nets test real triangle overlap, grow from the largest
chart and are packed side by side
- UV edits are stored per unwrapped copy, so dragging a seam vertex no
longer moves its copies in neighbouring islands
- UV pane: tool strip with unwrap settings moved in from the panel, sharp
HiDPI icons, clearer island/edge/selection drawing with hover, texture
picker from the thumbnail, texture no longer lost on reopen (GL state
from the 3D view, background upload retries)
- Panel: whole-model select/erase as icons in the tools row; inactive
layers' paint shown muted; colour textures shown in colour in the picker
- Built-in displacement texture library
- Tests for unwrap segmentation, connected nets, UV edits and per-layer
sampling
The remote's 3aefae016f is the same tree as local e245f5d069, and every change
in 013ac898ba (continuous smoothing, world-space bake, mirrored/scaled
placements, plate clamp, UV editor framing/HiDPI, layer scrolling) was already
carried forward and reworked by the local commits. Resolved to the local side.
