// .NAME vtkThresholdTextureCoords - compute 1D, 2D, or 3D texture coordinates based on scalar threshold
// .SECTION Description
// vtkThresholdTextureCoords is a filter that generates texture coordinates for
// any input dataset type given a threshold criterion. The criterion can take
// three forms: 1) greater than a particular value (ThresholdByUpper());
// 2) less than a particular value (ThresholdByLower(); or 3) between two
// values (ThresholdBetween(). If the threshold criterion is satisfied,
// the "in" texture coordinate will be set (this can be specified by the
// user). If the threshold criterion is not satisfied the "out" is set.
// .SECTION Caveats
// There is a texture map - texThres.vtk - that can be used in conjunction
// with this filter. This map defines a "transparent" region for texture
// coordinates 0<=r<0.5, and an opaque full intensity map for texture
// coordinates 0.5<r<=1.0. There is a small transition region for r=0.5.
