Heres another example, of a field representing streamlines round a cylinder:

Now presumably I could combine the locator with some function as in the mandelbrot example to find out the state of the streamlines at any point in the flow. Presumably the locator could also be extended to 3D.
Andy, if I read that example correctly '2D coordinates' there are meant to represent some physical dimensions, while here we are talking about a way to index an n-dimensional raster. That's quite a different world. FWIW, I believe the same reasoning can be applied to the color-space discussion. While I think a good library to deal with color spaces and transformations between them would be nice, that is a different domain than how colors are represented essentially as bit-fields in pixels. You were proposing not to lump independent concepts / domains together, so let's keep them separate ! ;-) Regards, Stefan -- ...ich hab' noch einen Koffer in Berlin...
