Mimas & Herschel Crater

Post #1by ron » 12.05.2002, 14:05

has anyone considered building a 3D model of Mimas to replace the existing sphere with an object that can better model the giant herschel crater. The 3D model itself can be a simple sphere for the rest of the moon but giving the herschel crater some relief should make it more impressive and better demonstrate it's size.

Bjorn Jonsson's Mimas

Bjorn Jonsson (who I think is the author of Celestia's Saturn ring texture) experimented with bump maps and triangle meshes for Mimas in POV-Ray:

This data could probably be translated into something usable by Celestia. There were some horizontal artifacts apparently generated by his bump-map-extraction method.

Ron,

See the topic at http://www.shatters.net/forum/viewtopic.php?p=27616#27616
for more info and a picture of Mimas as I have it on my version of Celestia.

Take care, Bob
