public class ModelLUT
extends ModelStorageBase

Model of a Lookup Table (LUT). At present, one can construct 10 different LUTs: GRAY, SPECTRUM, HOTMETAL, COOLHOT, SKIN, STRIPED, RED, GREEN, BLUE, GRAY_BR, and BONE. This class allows the programmer to specify the number of colors for the LUT. The LUT extents should be 4 x 256 or problems may arise with the differing colormaps (This class can be extended to handle arbitrary size LUTs but 256 is almost universal). There are 256 locations with alpha, red, green, and blue values as floats in order to store both RGB or HSI or etc. The LUTs are calculated from the corresponding transfer functions for each of a, r, g, and b.
