Athena: Cheap(er) Per-Pixel Directional Lighting (cont)
In my previous blog entry, Athena: Cheap(er) Per-Pixel Directional Lighting, I wrote how I had an idea for post process lighting calculations. Well, like many other things, it has already been done before, in fact a long time ago, 1988. It is known as Deferred Shading.
The wiki article also mentions something else that I didn't take into considering, and that is transparent objects, since there would be more than one lighting equation needed.
On the whole though, I'm glad I got a chance to implement it, one more thing I know how to do.
