"A 2D map of C-G seems like a tough order; the projection math alone..." Don't worry! If you can put a grid on the surface (as we have seen already), you can warp that grid into any map projection you like. Mapping will be no huge problem - in fact I expect they have a rough one already (I've been playing with one myself). Phil -------------------- ... because the Solar System ain't gonna map itself.

QUOTE Is that your own shapemodel or is it something ESA have made that is in the public domain? no it is all mine i used motion to make a "point cloud" from two videos then meshed it and just finished a rough edit i am about to add details from the images using "shape from shade" an old bit of code from a siggraph paper "mini_sfs" and a newer phd paper and code http://code.google.com/p/hyperion-cv/ i have NOT uploaded version TWO yet version 1 is here https://googledrive.com/host/0B6ZYAd08tZL-V...21-2014Mesh.zip --- VERSION 2 is here "67P.09.03.2014.zip" https://googledrive.com/host/0B6ZYAd08tZL-V....09.03.2014.zip |
