Detailed Description

a cell that represents a 3D orthogonal parallelepiped

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.
