Ok. I totally suck at OpenGL. I don’t understand anything, least of all Vertex and Fragment shaders. What do I do? I went to NEHE, etc… But they all have tuts, that show you HOW to do something, I want to know HOW it works and WHY. I need to know things like: What is a Vertex shader and why should I use it? Are display lists fast enough to actually make use of them? Why are fragment shaders talked about so much, and what do they do? Why should I learn Vertex and Fragment shaders (Cg in short) if GLSL is about to be released? Why can’t I understand multitexturing? Do you understand my delema yet? I just don’t understand any of it. I do know HOW to draw things on the screen using OpenGL. But when it comes to advanced things like shaders, advanced texturing, lighting, etc, I am lost. Exspecially when speed is of the essence. Extensions blow my mind! Help me please.
The reson this is in the “Advanced OpenGL” subtopic is because I do know the basics of OpenGL, I just don’t understand anything that isn’t basic. I tried google, NEHE, gamedev, etc… But I really just need some things explained to me.
