* @brief 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.
