* Ignore Clipper, libpng, mcut and Boost.Polygon Internals in clang-tidy
Each only works through a wrapper or umbrella header: libslic3r/clipper.hpp or clipper_z.hpp configure Clipper before including it, png.h pulls in libpng's config headers, and Boost.Polygon's headers only compile through polygon.hpp or voronoi.hpp.
* Ignore minilzo's Config Headers in clang-tidy
lzoconf.h and lzodefs.h are internal to minilzo.h, which is what the code includes.
* Add Missing Includes Across the Remaining Sources and Tests
Covers src/slic3r/Utils, src/slic3r/plugin, src/slic3r/Config, src/libvgcode, src/dev-utils, src/OrcaSlicer.cpp and tests/, the directories left after src/slic3r/GUI and src/libslic3r. Generated with clang-tidy misc-include-cleaner. libvgcode's own headers are included by relative path as in the rest of that library, and Catch2 and pybind11 with angle brackets as elsewhere in the repo.
* Make the GUI and Test Headers Compile on Their Own
Each now includes, or forward-declares, what it uses instead of relying on what its includers happened to include first. Headers that only compile on one platform, or that nothing built includes, are left alone.
* Keep Windows and nanosvg Setup Ahead of the Added Includes
OrcaSlicer.cpp and several tests set _WIN32_WINNT, WIN32_LEAN_AND_MEAN or NOMINMAX before including Windows.h, and the profile validator defines NANOSVG_IMPLEMENTATION before any libslic3r header. The added includes had landed above those blocks, which broke the Windows build.
* Add the GUI Includes the First Pass Missed
Covers headers that only became editable once they compiled on their own, and wx symbols whose suggested header changed as the clang-tidy ignore list grew after the src/slic3r/GUI pass.
* Keep the Added Test Includes Below the NOMINMAX Guard
test_marchingsquares.cpp and test_texture_displacement.cpp had includes inside #ifndef NOMINMAX, which the tests inherit as defined on Windows from libslic3r, so those were skipped there. .clang-tidy also ignores the MSVC STL and UCRT internals, Boost.Multiprecision's fwd.hpp and CPython's Windows include directory, as in #16068.
* Fix fuzzy skin failing the slice: the minimum junction width was unscaled
* Unit Tests For Fuzzy Fix
* Cover ridged multifractal noise in the fuzzy skin width floor test
Its output is not bounded to [-1, 1], so it scales past the configured
thickness and drives the junction width negative. The floor has to hold
for any noise value, not just an in-range one.
* fix: prevent out-of-bounds crash in Arachne beading interpolation
SkeletalTrapezoidation::interpolate() derives an inset index from `left` but
uses it to index the merged beading, which follows the thicker of left/right.
When the thicker side has fewer insets, the index runs past the end and the
slicer crashes during "Generating walls".
Skip the adjustment when the index is out of range, as the adjacent guards
already do. interpolate() uses no instance state, so make it static and add a
regression test that exercises it directly.
Fixes#14584
* Add test for Arachne duplicate wall segment detection
Add test cases that reproduce an issue where Arachne generates
duplicate/coinciding extrusion segments at certain min_bead_width settings.
Test configuration:
- Profile: 0.28mm Extra Draft @BBL X1C (0.4mm nozzle, 0.28mm layer)
- outer_wall_line_width: 0.42mm, inner_wall_line_width: 0.45mm
- wall_loops: 2, precise_outer_wall: enabled
- Test polygon: outer rectangle (0,0)-(20,20) with inner cutout (0.5,0.5)-(19.5,19.5)
This creates a 0.5mm wide frame around the perimeter.
Results:
- 50% min_bead_width (0.20mm): FAILS - detects 4 duplicate segments (all 4 sides)
- 60% min_bead_width (0.24mm): PASSES - no duplicates
At 50%, Arachne generates two separate closed loops that share all 4 edges
of the inner square. At 60%, Arachne generates a single closed loop.
SVG output is exported to /tmp/opencode/ for visual debugging.
* Fix Arachne duplicate extrusion caused by bead count mismatch
WideningBeadingStrategy::compute() used optimal_width (inner wall width)
to determine if a thin wall should produce a single bead. However,
getOptimalBeadCount() uses optimal_width_outer (outer wall width) via
RedistributeBeadingStrategy to decide the bead count.
This inconsistency caused situations where getOptimalBeadCount() returned
2 beads, but compute() produced only 1 bead at full thickness. The single
bead was then generated for both inner and outer contours, resulting in
duplicate extrusion paths.
Fix: Use getTransitionThickness(1) instead of optimal_width. This method
returns the exact threshold for the 1-to-2 bead transition, ensuring
consistency between bead count calculation and bead generation.
Reproduces with: 50% min_bead_width, 0.42mm outer wall, 0.45mm inner wall,
0.5mm polygon inset creating ~0.38mm wall thickness.
