vtkTriangularTCoords
Section: Visualization Toolkit Graphics Classes
Usage
vtkTriangularTCoords is a filter that generates texture coordinates
for triangles. Texture coordinates for each triangle are:
(0,0), (1,0) and (.5,sqrt(3)/2). This filter assumes that the triangle
texture map is symmetric about the center of the triangle. Thus the order
Of the texture coordinates is not important. The procedural texture
in vtkTriangularTexture is designed with this symmetry. For more information
see the paper "Opacity-modulating Triangular Textures for Irregular
Surfaces," by Penny Rheingans, IEEE Visualization '96, pp. 219-225.
To create an instance of class vtkTriangularTCoords, simply
invoke its constructor as follows
obj = vtkTriangularTCoords
Methods

In the methods listed below, obj
is an instance of the vtkTriangularTCoords class.
-
string = obj.GetClassName ()
-
int = obj.IsA (string name)
-
