Hi all, I am a new mayavi user and am trying to replicate the simple IDL behaviour of it's surf function. There, when I have a grey-scale image, for example, I can just give it to the 'surf-'function, and it plots a 3D graph, taking the luminance values of the image as elevation for the 3D display. Does this not exist in mayavi? I tried to use mlab.surf for 2 hours now, but I just can not understand all these grid creation stuff, as I never needed that in IDL, is that really necessary to just plot the image as a 3D object? Everything I tried with mlab.surf just gave me a flat object. I can run the example code for mlab.surf fine, but I am afraid I am doing something wrong, when i create the x and y grid, which would contain nothing but the index values of the image data anyway. Shouldn't this be simpler? Maybe I just missed something? I am grateful for any hint!
