vtkBooleanTexture is a filter to generate a 2D texture map based on combinations of inside, outside, and on region boundary. The "region" is implicitly represented via 2D texture coordinates. These texture coordinates are normally generated using a filter like vtkImplicitTextureCoords, which generates the texture coordinates for any implicit function.
vtkBooleanTexture generates the map according to the s-t texture coordinates plus the notion of being in, on, or outside of a region. An in region is when the texture coordinate is between (0,0.5-thickness/2). An out region is where the texture coordinate is (0.5+thickness/2). An on region is between (0.5-thickness/2,0.5+thickness/2). The combination in, on, and out for each of the s-t texture coordinates results in 16 possible combinations (see text). For each combination, a different value of intensity and transparency can be assigned. To assign maximum intensity and/or opacity use the value 255. A minimum value of 0 results in a black region (for intensity) and a fully transparent region (for transparency).
