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
