Hi,
I'm always been a lurker here. This is a great forum! Thanx to all! I've written a small script in Python that extract the elevation map from an image with lights and shadows. It's a technic called "shape from shading" or photoclinometry. I've applied a simplified algorythm that works only with particular conditions. For example light must come exactly from left to right. It works well only with no patterned images and output images are affected by a boring striped pattern. Btw, I've worked on an Enceladus crater an this is the result. 3D rendering is by GRASS software. In attachments there are the image of the crater, the 3D image and a map with profiles. ale |

Neato, Paul! Would you happen to have anaglyphs? --Emily dang, its not stereo in this specific example. I could create a synthetic stereo image from the topo map tho not for a bit cause of the things on my plate right now. I attach the color coded topo map of this scene from a vertical perspective (reduced by 50%), which i may post online later as well. cheers paul -------------------- Dr. Paul Schenk, Lunar and Planetary Institute, Houston TX
