unity-voxel

Voxelize mesh algorithm in Unity. (includes GPU and CPU voxelizers.)

GPUVoxelParticleSystem

the Demo for GPU Particle with geometry shader. (only tested on windows10 (GTX 1060))

Inspired by Keijiro Takahashi works⚡️ StandardGeometryShader & KvantSpray

GPUVoxelMosaic

the Demo to update the resolution of voxels in realtime. (only tested on windows10 (GTX 1060))

GPUVoxelSkinnedMesh

Sample a mesh from SkinnedRenderer in every frame and voxelize it in realtime.

the human model and animation from asset store.

Usage

with GPU Voxelizer (recommended)

…

with CPU Voxelizer

// Voxelize target mesh with CPU Voxelizer

List<Voxel> voxels = CPUVoxelizer.Voxelize(
    mesh,   // a target mesh
    20      // # of voxels for largest AABB bounds
);

Compatibility

Tested on Unity 2018.3.0f2, windows10 (GTX 1060), macOS (metal, not compatible with GPU Particle Demo).
