I have a voxel representation of a model of the human body in `numpy` and would like to render it directly in Blender. Is there a file format for this? Most of the ones I've seen use polygonal meshes (ie. .obj files). In other words, could one render Minecraft directly in Blender? (or if not, in Unity3D, Maya, UnrealEngine, or any other popular modeling 3-D software?)
