A fully managed .NET library for voxelization, meshing, and distance field computation. It is written entirely in C#, requires no external dependencies, and is designed for easy integration into .NET projects.

Features

Voxelization

  • Anisotropic voxelization (non-uniform voxel sizes)
  • Dense occupancy grids
  • Sparse boundary voxelization
  • Extensible grid structures via IGrid<T> interface and GridBase class

Distance Fields

  • Euclidean distance transform (exact, isotropic and anisotropic)
  • Signed distance field (SDF) generation
  • Sampling with nearest-neighbor or trilinear interpolation
  • Gradient computation from SDFs

Meshing

  • Face-culling voxel meshing

Grid Processing

  • BFS-based flood fill for interior/exterior classification

Supported Geometries

  • Triangle meshes (indexed and unindexed)
  • Polyline

Use Cases

  • Preprocessing 3D meshes into voxel grids
  • Generating SDFs for geometry processing, physics, or rendering
  • Mesh extraction from voxel volumes
  • Spatial analysis and computational geometry research

Supported Frameworks

  • .NET Standard 2.1
  • .NET 7.0
  • .NET 8.0
  • .NET 9.0
