I need to create good looking lightning using OpenGL ES 1.1 (iPhone) and was planning on using shaders. However, when I asked about it in a previous question (OpenGL ES 1.x Shaders) I was informed there that this was probably not an option on the iPhone.

So now I am back at square one, wondering how I might make a lightning animation. It does not need to look ultra-realistic. I have already tried to use things like triangles stripped together. While this method does work, it is not as good as I had hoped it would look.

Does anyone have any ideas on the subject?

Thanks again,
~Eric

    The usual approach is to compute the path of the lightning bolt using a Perlin function, rendering it to a glow buffer, creating a nice looking blur using a Gaussian blur shader and then merge it with your scene.
