/**
* This function fills a 3D array with ambient occlusion values computed by raycasting through the volume.
* This approach to ambient occlusion is only appropriate for relatvely small volumes, otherwise it will
* become very slow and consume a lot of memory. You will need to find a way to actually use the generated
* ambient occlusion data, which might mean uploading it the the GPU as a volume texture or sampling on
* the CPU using the vertex positions from your generated mesh.
*
* In practice we have not made much use of this implementation ourselves, so you may find it needs some
* optimizations or improvements to be useful. It is likely that there are actually better approaches to
* the ambient occlusion problem.
*
* \param volInput The volume to calculate the ambient occlusion for
* \param[out] arrayResult The output of the calculator
* \param region The region of the volume for which the occlusion should be calculated
