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

 Fantastic stuff -- is it possible to rotate the highest resolution image (with boulders) and run the script on that? Any such product could be downsampled and still have great resolution -- could be used to produce a synthetic image of a horizon-looking panorama as seen from the surface. What could be cooler than that? |

Definitely fabulous -- can it be done with the highest resolution image from this last flyby? |

Hi guys,
nice work! Ive finally posted several of my own 3d rendered perspectives of Enceladus on Photojournal (got buried under the Plume PCon release pix). one view is attached. Hope to release some more of this and other moons in the coming weeks. Enjoy paul
