    * `obj_points`: A mesh containing a point cloud, with a vertex for each voxel. Can be viewed using any compatible viewer that can just display vertices, like [Blender](https://www.blender.org/) or [Meshlab](https://www.meshlab.net/).
    * `morton`: a binary file containing a Morton-ordered grid. This is an internal format I use for other tools.
  * `-cpu`: Force multi-threaded voxelization on the CPU instead of GPU. Can be used when a CUDA device is not detected/compatible, or for very small models where GPU call overhead is not worth it.
- * `-thrust` : Use Thrust library for copying the model data to the GPU, for a possible speed / throughput improvement. I found this to be very system-dependent. Default: disabled.
  * `-solid` : (Experimental) Use solid voxelization instead of voxelizing the mesh faces. Needs a watertight input mesh.
 
 ## Examples
 `cuda_voxelizer -f bunny.ply -s 256` generates a 256 x 256 x 256 vox-based voxel model which will be stored in `bunny_256.vox`. 
 
-`cuda_voxelizer -f torus.ply -s 64 -o obj -thrust -solid` generates a solid (filled) 64 x 64 x 64 .obj voxel model which will be stored in `torus_64.obj`. During voxelization, the Cuda Thrust library will be used for a possible speedup, but YMMV.
