Ok, ive decide if im going to stick with opengl then i need to learn shaders. So tonight i followed these tutorials as they came up on google and seemed easy enough.
But. im now like stuck, as ive done them and understand the use of them more but still cant like go ahead and start writnig my own, or using otheres quite yet. for instance, from them tuts i now know how to do per pixel lighting and texture a object using shaders, but not both together? Is there another site with good GLSL tutorials on?
Some questions i do have though are…
When you decide to use shaders what like commands do they actually take over and make redundant using openGL? For instance, can i use shaders to texture an object, but then still scale the texturing inside opengl? Or would you not even want to?
And other things like… If i say wanted, to have an object, textured with normal maps and per pixel lighting, is that all done in one shader or can it be done with like 2 or 3 shaders?
