3D models

Does anyone know how many polys celestia supports? or does it depend on your computer?

The 3ds file format, which Celestia supports, has a 64k poly limit per mesh. Other than that, it's probably a matter of how much memory you have.

I once made a model with over a million triangles with the cmod format. It ran on my older computer, less than 1 fps though. My older computer had a k7 processor and 512 mb ram and 256 mb video card. I ran it a couple of days ago on my newer box and it got about 10 fps. So the sky is the limit. :wink:

Yeah, cmod should get you pretty far. A 3ds model that you've divided into submeshes because of the size limit, can be converted using Celestia's cmodtools into a single cmod mesh if you want. Or you could write a direct-to-cmod export script for your modeling program like cartrite has done.
