* @brief generate 2D triangular texture map
|
||
|
|
*
|
||
|
|
* vtkTriangularTexture is a filter that generates a 2D texture map based on
|
||
|
|
* the paper "Opacity-modulating Triangular Textures for Irregular Surfaces,"
|
||
|
|
* by Penny Rheingans, IEEE Visualization '96, pp. 219-225.
|
||
|
|
* The textures assume texture coordinates of (0,0), (1.0) and
|
||
|
|
* (.5, sqrt(3)/2). The sequence of texture values is the same along each
|
||
|
|
* edge of the triangular texture map. So, the assignment order of texture
|
||
|
|
* coordinates is arbitrary.
