Detailed Description

a cell that represents a 2D quadrilateral

vtkQuad is a concrete implementation of vtkCell to represent a 2D quadrilateral. vtkQuad is defined by the four points (0,1,2,3) in counterclockwise order. vtkQuad uses the standard isoparametric interpolation functions for a linear quadrilateral.
