DESCRIPTION
vtkVoxel is a concrete implementation of vtkCell to represent a 3D orthogonal parallelepiped. Unlike vtkHexahedron, vtkVoxel has interior angles of 90 degrees, and
sides are parallel to coordinate axes. This results in large increases in computational performance.
vtkVoxel()
Construct the voxel with eight points.
vtkVoxel(const vtkVoxel& b)
Deep copy of cell.
