Detailed Description

generate 1D, 2D, or 3D texture coordinates based on implicit function(s)

vtkImplicitTextureCoords is a filter to generate 1D, 2D, or 3D texture coordinates from one, two, or three implicit functions, respectively. In combinations with a vtkBooleanTexture map (or another texture map of your own creation), the texture coordinates can be used to highlight (via color or intensity) or cut (via transparency) dataset geometry without any complex geometric processing. (Note: the texture coordinates are referred to as r-s-t coordinates.)

The texture coordinates are automatically normalized to lie between (0,1). Thus, no matter what the implicit functions evaluate to, the resulting texture coordinates lie between (0,1), with the zero implicit function value mapped to the 0.5 texture coordinates value. Depending upon the maximum negative/positive implicit function values, the full (0,1) range may not be occupied (i.e., the positive/negative ranges are mapped using the same scale factor).

A boolean variable InvertTexture is available to flip the texture coordinates around 0.5 (value 1.0 becomes 0.0, 0.25->0.75). This is equivalent to flipping the texture map (but a whole lot easier).

Warning:
You can use the transformation capabilities of vtkImplicitFunction to orient, translate, and scale the implicit functions. Also, the dimension of the texture coordinates is implicitly defined by the number of implicit functions defined.

Member Function Documentation

virtual const char* vtkImplicitTextureCoords::GetClassName  )  [virtual]
 

Reimplemented from vtkDataSetToDataSetFilter.

int vtkImplicitTextureCoords::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 vtkDataSetToDataSetFilter.

virtual int vtkImplicitTextureCoords::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 vtkDataSetToDataSetFilter.

vtkImplicitTextureCoords* vtkImplicitTextureCoords::SafeDownCast vtkObject o  )  [static]
 

Reimplemented from vtkDataSetToDataSetFilter.

void vtkImplicitTextureCoords::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 vtkDataSetToDataSetFilter.

vtkImplicitTextureCoords* vtkImplicitTextureCoords::New  )  [static]
 

Create object with texture dimension=2 and no r-s-t implicit functions defined and FlipTexture turned off.

Reimplemented from vtkAlgorithm.

virtual void vtkImplicitTextureCoords::SetRFunction vtkImplicitFunction  )  [virtual]
 

Specify an implicit function to compute the r texture coordinate.

virtual vtkImplicitFunction* vtkImplicitTextureCoords::GetRFunction  )  [virtual]
 

Specify an implicit function to compute the r texture coordinate.

virtual void vtkImplicitTextureCoords::SetSFunction vtkImplicitFunction  )  [virtual]
 

Specify an implicit function to compute the s texture coordinate.

virtual vtkImplicitFunction* vtkImplicitTextureCoords::GetSFunction  )  [virtual]

virtual vtkImplicitFunction* vtkImplicitTextureCoords::GetTFunction  )  [virtual]
 

Specify an implicit function to compute the t texture coordinate.

virtual void vtkImplicitTextureCoords::SetFlipTexture int   )  [virtual]
 

If enabled, this will flip the sense of inside and outside the implicit function (i.e., a rotation around the r-s-t=0.5 axis).

virtual int vtkImplicitTextureCoords::GetFlipTexture  )  [virtual]
 

If enabled, this will flip the sense of inside and outside the implicit function (i.e., a rotation around the r-s-t=0.5 axis).

virtual void vtkImplicitTextureCoords::FlipTextureOn  )  [virtual]
 

If enabled, this will flip the sense of inside and outside the implicit function (i.e., a rotation around the r-s-t=0.5 axis).

virtual void vtkImplicitTextureCoords::FlipTextureOff  )  [virtual]
 

If enabled, this will flip the sense of inside and outside the implicit function (i.e., a rotation around the r-s-t=0.5 axis).
