Detailed Description

2D texture coordinates based for triangles.

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.

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

static int vtkTriangularTCoords::IsTypeOf ( const char *  name) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

virtual int vtkTriangularTCoords::IsA ( const char *  name) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

void vtkTriangularTCoords::PrintSelf ( ostream &  os,
vtkIndent  indent 
) [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkPolyDataAlgorithm.

int vtkTriangularTCoords::RequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
) [protected, virtual]

This is called by the superclass. This is the method you should override.

Reimplemented from vtkPolyDataAlgorithm.
