Still working on those wacky spheres
Posted: 16.02.2009, 19:51
So, for the sake of experimentation, fsgregs was kind enough to lend me a couple sphere models that Jestr had made for him a while back. Without any celestia modeling skills of my own, aside from the point-to-point, hand-coded, straight line variety, I've been attempting to modify the existing models which consist of a cmod and a .dsc file.
The original model was for a transparent sphere centered on Sol with a simple enough .dsc...
I'm trying to center my sphere on a specific point elsewhere. I've created an stc file that marks that point, but when I enter the same RA, Dec, and Distance for my point into the dsc for the model the end result is ending up somewhere quite different.
The distance looks right but the RA and Dec appear to have become skewed. Does anyone have any advice for where I might be going wrong here?
