Every libslic3r source and header now directly includes the headers declaring what it uses, rather than relying on the precompiled header or transitive includes. Generated with clang-tidy misc-include-cleaner, with libslic3r headers spelled libslic3r/... so they resolve outside the library's private include paths. MultiMaterialSegmentation.hpp, Support/SupportParameters.hpp and Format/STEP.hpp are made self-contained by hand.
Refinement now tapers off away from the paint, and the unpainted surface is kept out of
simplification, so what one bake leaves unpainted is still the model's own triangles when a later
bake paints there. A second bake used to refine the slivers and long triangles the first one left
around its stroke, and came out many times denser, with walls off the texture's lines.
Meeting the triangle budget by merging flat faces alone no longer raises the warning, and the
warning now quotes the budget instead of the triangle count left after the flat faces were merged.
texture_displacement_patch_frame picks the world axis least aligned with
the patch's average normal. With no patch there is no normal either, and
the axis came out of the +Z fallback for it - so it was +X, while its
test asked for the upright frame the fallback is meant to give. An empty
patch now answers +Z outright.
Nothing removed the even mesh over a texture's flat parts unless the
budget was lowered until simplification had to run. Collapses stay under
a thirty-second of the resolution: on the test map 387584 -> 369876
triangles, with the print unchanged (0.02% of the extrusion).
An earlier attempt was reverted for a 21% heavier result. That was the
colour despeckle switching itself off, not the collapsing: it keyed off
the face parent map, which any collapse empties.
Relief preserved from an earlier bake is counted on top of the budget
instead of eating into it: baking a second area went from ~214 k
triangles to the ~1000 k it was given.
When the resolution needs more triangles than the budget allows, it is
said before the bake under Resolution and again afterwards.
- 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
Colour height maps now displace the same way up as grayscale ones. A
truncated or corrupt PNG in the texture folder or a project file now
loads as an empty texture instead of aborting the app, and a 16-bit
colour PNG is converted on load rather than displacing as noise.
