I now have a greatly improved version of the Enceladus DEM mentioned near the end of this thread.
I used this new DEM to do a 951 frame flyby animation. The field of view is 40 degrees and we get as close as ~140 km from the surface. Vertical relief is exaggerated by a factor of 2. The animation requires the DivX codec. It can be downloaded here (5.6 MB): http://www.mmedia.is/bjj/misc/css_stuff/an...el_dem_anim.avi A sample frame from the animation: It should be noted that a lot of the small scale details are from the texture map draped over the DEM and not from the DEM itself. The resolution of the DEM is several times lower than the resolution of the images used to create the DEM. This is what the DEM looks like when the texture map is omitted: Not nearly as pretty as the sample frame above but at least it's obvious what this is. The entire DEM looks like this: The altitude range is ~4 km. The quality of this DEM is somewhat lower than the quality of the Iapetus DEM mentined here a few times in the past several weeks (in particular here). However, it's much better than the Mimas DEM mentioned in this thread. This is an elevation profile through one of the craters (distances are approximate): And the profile's location: |

Bjorn...major WOW!!! That animation was just amazing, beyond professional quality!
