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