41 // .NAME vtkBooleanTexture - generate 2D texture map based on combinations of inside, outside, and on region boundary
42 // .SECTION Description
43 // vtkBooleanTexture is a filter to generate a 2D texture map based on
44 // combinations of inside, outside, and on region boundary. The "region" is
45 // implicitly represented via 2D texture coordinates. These texture
46 // coordinates are normally generated using a filter like
47 // vtkImplicitTextureCoords, which generates the texture coordinates for
48 // any implicit function.
50 // vtkBooleanTexture generates the map according to the s-t texture
51 // coordinates plus the notion of being in, on, or outside of a
52 // region. An in region is when the texture coordinate is between
53 // (0,0.5-thickness/2). An out region is where the texture coordinate
54 // is (0.5+thickness/2). An on region is between
55 // (0.5-thickness/2,0.5+thickness/2). The combination in, on, and out
56 // for each of the s-t texture coordinates results in 16 possible
57 // combinations (see text). For each combination, a different value of
58 // intensity and transparency can be assigned. To assign maximum intensity
59 // and/or opacity use the value 255. A minimum value of 0 results in
60 // a black region (for intensity) and a fully transparent region (for
63 // vtkImplicitTextureCoords vtkThresholdTextureCoords
