What exactly is a Pixel Shader? I've read that
they're little programs that run over each pixel,
but I dont' quite understand this. What do they
do? What are they used for? How do they work? etc.
Also, can these only be used through DirectX 8?
Everything I've read about Pixel/Vertex Shaders
is mentioned in articles talking about DirectX 8.
What about OpenGL poeple? Are there special
extension-things for them?
Anyway, since I'm already here... What's a Vertex
Shader? How are Vertex Shaders different from
I don't know much about DirectX or OpenGL.
