Let's say I created a space scene in OpenGL ES 2 similar to this one:
At the moment my sun is just a small texture similar to the one in the image that I place somewhere far, but it obviously looks very static. How would I make my sun shine & look alive?
EDIT: This is just an example image and all I care about is the sun. In my implementation the lighting and everything else is fine, but the sun itself (which is just a texture at the moment), doesn't "animate"/shine at all. I'm trying to find out how to make my sun shine and look like it's alive.
