Celestia Forums

I'm unable to reproduce a proper atmosphere on models, with Celestia 1.5.0, like what Chris has shown before. Here's what I get on a simple disk shaped 3ds model :



Here's the SSC code I'm using for this :



If I rise up the atmosphere height by a factor of 10 or 100, I get some weird rendering, like this :



I strongly suspect it isn't a bug in my video card drivers. I strongly feel it's a bug in Celestia, (Mac version ?) .

Maybe this bug is related to the fact that there's a star at the center of the mesh ?

There are two sets of parameters for atmospheres: the old ones that you're using, and the new ones for 1.5.0 that do a simple scattering simulation. Only the new ones give a volumetric effect, and even then they're really designed to be used with spheres (or ellipsoids), not just any old mesh.

Chris,

then, can you give an explicit example of code that defines a volumetric atmosphere ? What did you used, in your example around an asteroid (the model wasn't exactly spherical, if I remember !).
