Release v0.8.7

Features

• Graceful CUDA Extension Fallback (conquer3d._extension):

  • Implemented lazy loading and missing extension stand-in module (_MissingExtension) for conquer3d._C.
  • Enables importing conquer3d in environments without a compiled CUDA extension (e.g. CI runners, documentation builders, static analysis tools, and CPU-only hosts).
  • Exposes HAS_EXTENSION: bool, ExtensionUnavailableError, and extension_error() for explicit backend inspection.
  • Dynamically substitutes missing CUDA symbols with helpful placeholder types that raise ExtensionUnavailableError with compilation instructions (TORCH_CUDA_ARCH_LIST) upon invocation.

• Top-Level Package Geometric Exports (conquer3d):

  • Elevated primary spatial structures directly into conquer3d root namespace: BVH, GSBVH, KDTree, MeshBVH, PGSBVH, and TriangleMesh.

Refactors & Build

• Build System:
  • Renamed CMake project from GeoCuTool to Conquer3D in CMakeLists.txt.
  • Bumped library version to 0.8.7 in pyproject.toml.
• Documentation:
  • Added interactive higher-order Laplacian fairing showcases and pinned patch smoothing demonstrations.
  • Archived v0.8.5 API documentation and rebuilt documentation assets.

Examples

• Non-GPU environments importing and inspecting conquer3d without requiring CUDA compilation.
• Direct root imports: from conquer3d import TriangleMesh, BVH, KDTree.
