The r, g, b, t values should be between 0 and 1. This can be done using a homemade function "snt_makecolorwave_manrange" in our group. The color wave should be made for each data and for each color scale. Additionally, the transparency factor alpha is stored at CW(a, b, 3) as CW(a, b, 3) = alpha. b) for a pixel at (a, b) in the original 2D matrix data is stored in the color wave CW(i, j, k) as CW(a, b, 0) = r, CW(a, b, 1) = g, CW(a, b, 2) = b. The layer k corresponds to the r, g, b and t components of the RGB color. The row i and column j corresponds to the row and column of the original 2D wave.
(If you don't want to specify the transparency level, the color wave dimension can be m x n x 3.) The 4 layers are for r, g, b and a for transparency. If the dimension of the original 2D matrix data is m x n, then the dimension of the color wave should be m x n x 4. To give a special color to the 3D surface other than the fixed colors or the built-in color tables, you need to make your own color wave against the data. You can colorize the surface using a fixed color or built-in color tables.
