Hi Ashli,
This utility will "voxelise" your mesh. Then you can use that image as a logical index into your 3d image:
Also, on the off chance that all of your objects are convex, then there is an approach to this with vert2con() on the FEX that will quickly allow you to identify whether a voxel is inside the vertices.

If your volume is tesselated with triangles and watertight, you might be able to use intriangulation from the FEX.
