## Detailed Description

a 3D cell that represents a linear pyramid

Date:
  2003/01/06 20:36:14

Revision:
  1.26

vtkPyramid is a concrete implementation of vtkCell to represent a 3D pyramid. A pyramid consists of a rectangular base with four triangular faces. vtkPyramid uses the standard isoparametric shape functions for a linear pyramid. The pyramid is defined by the five points (0-4) where (0,1,2,3) is the base of the pyramid which, using the right hand rule, forms a quadrilaterial whose normal points in the direction of the pyramid apex at vertex #4.
