Choose strategy to rasterize per tetrahedron or voxel
Per voxel we will have weights to each vertex such that the value at that voxel is a linear combination of said weights.
Precompute m_Next(Row/Column/Slice)Additions weights which are later used to compute gradient basis vectors which are then used to calculate the final gradients per vertex.
