茂之钳	5cfdcb2aad	refactor: strip non-kernel code — keep pure geometry engine only ... Removed (application layer, not kernel): - blender_addon/ — Blender plugin - dotnet/ — .NET/C# bindings - viewer/ — Web 3D viewer - include/vde/ai/ — AI/ML (GNN, generative design) - include/vde/cloud/ — Cloud-native (OT, sessions) - include/vde/distributed/ — Cluster computing - include/vde/kbe/ — Knowledge-based engineering - include/vde/wasm/ — WASM compilation - include/vde/digital_twin/ — Digital twin - include/vde/plugin/ — Plugin system - include/vde/gpu/ — GPU acceleration - src/ai/, src/cloud/, src/distributed/, src/kbe/, src/wasm/, src/digital_twin/, src/plugin/, src/gpu/ - tests/ai/, tests/cloud/, tests/distributed/, tests/kbe/, tests/gpu/ Kept (pure geometry kernel): - brep/ curves/ mesh/ core/ foundation/ spatial/ boolean/ collision/ sdf/ sketch/ capi/ - python/ bindings (kept as thin binding layer) Rationale: Parasolid/ACIS/CGM are pure kernels. AI, cloud, WASM, digital twin, Blender plugins, .NET bindings, and Web viewers belong in the application layer, not in the geometry engine. VDE should focus on being the best geometry kernel.	2026-07-27 00:05:24 +08:00

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	4a32633482	feat(v3.3): NURBS surface-surface intersection ... Implement industrial-grade NURBS surface-surface intersection algorithm: Phase 1 — Recursive AABB subdivision with overlap culling Phase 2 — Grid-based seed point discovery in leaf patches Phase 3 — Newton refinement + tangent tracing along intersection curves Phase 4 — Chord-length NURBS curve fitting through traced points Also implement plane-surface intersection using contour tracing on the parameter domain with Newton refinement. New files: - include/vde/curves/surface_intersection.h (IntersectionCurve struct, APIs) - src/curves/surface_intersection.cpp (full algorithm implementation) - tests/curves/test_surface_intersection.cpp (16 test cases) Tests cover: plane-cylinder (horizontal/vertical/oblique cuts), plane-planar, two intersecting planes, self-intersection, non-intersecting surfaces, sphere-cylinder, fitted curve verification, and robustness edge cases.	2026-07-24 13:07:45 +00:00
