"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.

Blender is not a "cad/cam" set-up
so the dimensions are NOT in Meters or KM also depending on what software you are using to import the mesh , it might be big or small but the proportions will not change |

I'm manually placing all the markers on each image to make sure that there is maximum precision in the camera solve. I'm calibrating the scale to match the spacecraft distances that ESA give for the images. I will drop that data into Nuke to generate a dense cloud by stereo correlation. Then I will add the last bit of detail using SFS. There will probably be a bit of 3dsmax aswell. |
