In Topic: Representing points projected onto a sphere in two dimensions

31 January 2013 - 09:52 PM

I don't understand the problem. You could render your realistic starfield texture on a 3D sphere centered on the camera, perspective transformation will take care of the rest. Or are you doing something else?

 

I don't want to render a 3d sphere... I want to procedurally generate stars but I don't want to render any 3d objects. If you look at this video - http://www.youtube.com/watch?feature=player_detailpage&v=py2OeGYhZVw#t=65s - and watch as he clicks and pans the camera around, that's the effect I want to simulate but in 2d.

 

What's a starting point for me to study to be able to create this kind of effect using only two dimensions?

 

Thanks again!
