## Detailed Description

generate 2D triangular texture map

Date:
  2002/06/12 17:33:45

Revision:
  1.24

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]`

| Reimplemented from vtkImageSource.

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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkImageSource.

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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkImageSource.

vtkTriangularTexture* vtkTriangularTexture::SafeDownCast | ( | vtkObject * | o | ) | `[static]`

| Reimplemented from vtkImageSource.

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 vtkImageSource.

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 vtkObject.

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

| Set a Scale Factor.

virtual float vtkTriangularTexture::GetScaleFactor | ( |  | ) | `[virtual]`

| Set a Scale Factor.

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

| Set the X texture map dimension. Default is 64.

virtual int vtkTriangularTexture::GetXSize | ( |  | ) | `[virtual]`

| Set the X texture map dimension. Default is 64.

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

| Set the Y texture map dimension. Default is 64.

virtual int vtkTriangularTexture::GetYSize | ( |  | ) | `[virtual]`

| Set the Y texture map dimension. Default is 64.

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]`

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

virtual void vtkTriangularTexture::ExecuteInformation | ( |  | ) | `[protected, virtual]`

| Reimplemented from vtkSource.

virtual void vtkTriangularTexture::ExecuteData | ( | vtkDataObject * | data | ) | `[protected, virtual]`
