Having a 2D colormap is not currently supported in Mayavi. If you want to define your own 1D colormap (that can then be called 'LUT' for Look Up Table), you can insert a pre-computed table, as can be seen in the following example: http://code.enthought.com/projects/mayavi/docs/development/html/mayavi/auto/example_custom_colormap.html Hope this helps, Gaël ------------------------------------------------------------------------------ EditLive Enterprise is the world's most technically advanced content authoring tool.
