Voxelize mesh algorithm in Unity. (includes GPU and CPU voxelizers.)
the Demo for GPU Particle with Geometry shader. (only tested on windows10 (GTX 1060))
Inspired by Keijiro Takahashi works⚡️ StandardGeometryShader & KvantSpray
with GPU Voxelizer (recommended)
GPUVoxelData data = GPUVoxelizer.Voxelize( voxelizer, // ComputeShader (Voxelizer.compute) mesh, // a target mesh 64 // # of voxels for largest AABB bounds ); // build voxel cubes integrated mesh GetComponent<MeshFilter>().sharedMesh = GPUVoxelizer.Build(data); // release a voxel buffer data.Dispose();with CPU Voxelizer
// Voxelize target mesh with CPU Voxelizer List<Voxel> voxels = Voxelizer.Voxelize( mesh, // a target mesh 20 // # of voxels for largest AABB bounds );tested on Unity 2017.0.3, windows10 (GTX 1060), macOS (metal).
