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

Super Class: vtkDataSetToDataSetFilter

Description:

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).

Caveats:

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.
