It is a great program to convert 3D stl to voxels.
Is there a efficient way to rotate the voxel model for arbitrary angle? One way I think of is that I rotate the 3D stl model (calculate the new coordinates of each vertices of the facets) and voxelise the rotated 3D model. But the 'voxelise' itself is quite slow. Is there any way to rotate the voxel model itself? Will parallel processing possible in voxelise?
