I would like to implement something like this: http://www.noisemachine.com/talk1/imgs/flame500.html using Cg shaders. But do I need read an image of sun-like object and then generate the effects or is there someway to use OpenGL to create the initial image before implmenting the Perlin-Noise function in Cg?

There's a Corona example with FX Composer 2. it's a little complicated, but it might give you some hints.
