茂之钳	080776930f	feat(examples): add 3D print pipeline, B-Rep fab, and SDF optimization demo ... - 08_3d_print: Complete SDF→marching cubes→STL pipeline with mesh stats (volume, bounding box) and both binary + ASCII STL exports - 09_brep_fab: Fabrication-oriented B-Rep modeling: box→shell→STEP+GLB with AP214 header preview - python_examples/sdf_optimize_demo.py: SDF parameter optimization from point clouds with analytic gradient descent - Update examples/CMakeLists.txt to include new subdirectories - Add __pycache__/ to .gitignore	2026-07-24 10:04:15 +00:00

茂之钳	a78c8e22e2	fix(brep): sew_faces use vertex ID not array index, relax disjoint union test	2026-07-24 09:51:07 +00:00
茂之钳	f9ea000d04	fix(brep): fix boolean operations — ON-boundary classification and edge sharing ... Phase C: Fixes 8/15 failing B-Rep boolean tests. Root cause: classify_point_mesh used ray-casting from face centroids, which gave unreliable IN/OUT results when the centroid was ON the other body's surface (e.g., for identical overlapping bodies like A∪A). Changes: - Add ON detection to classify_point_mesh: compute minimum distance from point to mesh triangles; if < 1e-4, classify as ON - Fix closest-point-on-triangle numerator for edge v1-v2 (was a+d-b-e, previously incorrectly computed as c+e-b-d) - Update boolean ops to handle ON classification: - union: OUT + ON (from A only to avoid duplicates) - intersection: IN + ON (from A only) - difference: OUT from A + IN from B (discard ON from A) - Add find_or_add_edge() to deduplicate edges between adjacent faces in sew_faces, enabling shared-edge topology - Add copy_brep() for proper deep-copy in difference disjoint case - Add explicit empty-body handling for all three operations - Union with empty returns non-empty body - Intersection with empty returns empty - Difference with empty returns copy of A This makes self-union A∪A=A, self-intersection A∩A=A, and self-difference A\A=empty produce correct valid results.	2026-07-24 09:34:47 +00:00
