Detailed Description

generate 2D triangular texture map.

Date:

2000/12/10 20:08:56

Revision:

1.18

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.

Member Function Documentation

virtual const char* vtkTriangularTexture::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 vtkStructuredPointsSource.

int vtkTriangularTexture::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 vtkStructuredPointsSource.

virtual int vtkTriangularTexture::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 vtkStructuredPointsSource.

vtkTriangularTexture* vtkTriangularTexture::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 vtkStructuredPointsSource.

void vtkTriangularTexture::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.

vtkTriangularTexture* vtkTriangularTexture::New (    )  [static]

Instantiate object with XSize and YSize = 64; the texture pattern =1 (opaque at centroid); and the scale factor set to 1.0. Reimplemented from vtkStructuredPointsSource.

virtual void vtkTriangularTexture::SetScaleFactor (  float    )  [virtual]

Set a Scale Factor.

virtual float vtkTriangularTexture::GetScaleFactor (    )  [virtual]

virtual void vtkTriangularTexture::SetXSize (  int    )  [virtual]

Set the X texture map dimension. Default is 64.

virtual int vtkTriangularTexture::GetXSize (    )  [virtual]

virtual void vtkTriangularTexture::SetYSize (  int    )  [virtual]

Set the Y texture map dimension. Default is 64.

virtual int vtkTriangularTexture::GetYSize (    )  [virtual]

virtual void vtkTriangularTexture::SetTexturePattern (  int    )  [virtual]

Set the texture pattern. 1 = opaque at centroid (default) 2 = opaque at vertices 3 = opaque in rings around vertices

virtual int vtkTriangularTexture::GetTexturePattern (    )  [virtual]

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

Definition at line 96 of file vtkTriangularTexture.h.

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

Reimplemented from vtkSource.
