茂之钳	8f77d04283	fix(v4.2): boolean/validate/heal/step_export use vertex array index, not v.id ... Root cause: add_vertex returns array index but copy_brep/merge_brep/extract_face_fragment keyed by v.id (next_id_ value). When vertices and edges are interleaved, v.id != array index → map lookup fails → OOB access. Fixes in brep_boolean.cpp: - copy_brep: key by vertex index (vi) instead of v.id - merge_brep: key by vi, value = best_idx (array index) not result.vertex(id).id - extract_face_fragment: use body.vertex(e.v_start) directly (e.v_start is array index) - face_bounds/face_centroid/faces_intersect: same direct access pattern Also fixed same pattern in brep_heal.cpp, brep_validate.cpp, step_export.cpp	2026-07-25 05:50:56 +00:00

茂之钳	212c6a02c5	feat(v3.4): integrate face splitting into B-Rep boolean operations ... Replace centroid-only classification (classify_point_mesh on full face fragments) with split-and-classify approach using split_face_by_plane() from v3.3: - Add include for brep_face_split.h - Add face_normal() helper (extracts surface normal at parametric mid-point) - Add split_and_classify_faces(): splits each face of body A by the planes of every face in body B, then classifies each resulting fragment individually - Refactor brep_union, brep_intersection, brep_difference to use the new split-and-classify pipeline - Add test: Union_SelfUnion_WithSplitting This produces more precise boolean results by ensuring face fragments that straddle the boundary are properly split before classification.	2026-07-24 13:20:17 +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
