Detailed Description

2D texture coordinates based for triangles.

Date:

2000/12/10 20:08:56

Revision:

1.17

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.

Member Function Documentation

vtkTriangularTCoords* vtkTriangularTCoords::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkPolyDataSource.

virtual const char* vtkTriangularTCoords::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataToPolyDataFilter.

int vtkTriangularTCoords::IsTypeOf (  const char *    type )  [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 vtkPolyDataToPolyDataFilter.

virtual int vtkTriangularTCoords::IsA (  const char *    type )  [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. Reimplemented from vtkPolyDataToPolyDataFilter.

vtkTriangularTCoords* vtkTriangularTCoords::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataToPolyDataFilter.

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 vtkSource.

void vtkTriangularTCoords::operator= (  const vtkTriangularTCoords &    )  [inline, protected]

Definition at line 77 of file vtkTriangularTCoords.h.

void vtkTriangularTCoords::Execute (    )  [protected, virtual]

Reimplemented from vtkSource.
