Thanks @jttoombs for the heads-up.
The current OpenGL voxelizer reads the STL mesh and only voxelize the part of the mesh with positive z coordinate.
This post is to warn user of this limitation and track the progress of our fix.
Quick fix could be first translating the mesh with trimesh to all positive z before voxelization.
Eventual fix, as @jttoombs pointed out, could be using virtual coordinate in OpenGL.
