## Detailed Description

a cell that represents a 3D orthogonal parallelepiped

Date:
  2003/02/03 13:23:32

Revision:
  1.68

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.
