voxelize(mesh, size, solid=True)

source code

Voxelize a mesh into a cube of length size.

Parameters:

mesh (VertexArray) - The mesh to voxelize.
size (int) - The length of the resulting cube. Should be a multiple of 128.
solid (bool) - Whether to perform solid voxelization instead of boundary voxelization.

Attention: The result of boundary voxelization is likely to have holes. To obtain a watertight volume, you can voxelize the volume from different directions and combine the results, or use the gradient of a solid volume.
