Can you provide an example? Used geometry, voxelize parameters? This
behavior could be caused by using a too small voxel size (conversion
needs a long time).
You can find the core of the algorithm in /src/libanalyze/voxels.c.
The creation of the voxels will be done via the create_boxes callback
function. There are two such functions already implemented: One in
src/libged/voxelize.c which creates RPPs (the mged command) and
another in src/conv/g-voxel.c which writes the coordinates to a file.

Maybe you could think more about creating new call-back functions for
special purposes and how to integrate them in BRL-CAD.

This is another topic, similar to getting the lines and surfaces from a pixmap.
