   GLSL help
  Hey peeps, can someone please tell me how i can access the 'world'/'model' matrix in a GLSL vertex shader? Are they the same thing? Sorry I'm new to this  cheers   
  In OpenGL 'World' is the same as 'View', so when accessing in GLSL for ex., gl_ModelViewProjectionMatrix, you could treat it as gl_ModelWorldProjectionMatrix =]But you can't access Model or View seperatly inside GLSL... So there's only built-in variables like:gl_ModelViewProjectionMatrix,gl_ModelViewMatrix,gl_ProjectionMatrixBut no - gl_ModelMatrix or gl_ViewMatrixP.S and no - world (or view) and model isn't the same thing.   ;  As much as I don't want to become one of the depreciation harpies, you probably should not use the gl_whateverMatrix if you can avoid it. The proper way is to upload your own matrices via uniform.I think there are a lot of common graphical effects that you need separate model, view, and projection matricies for, so it is best to learn the right way to do it if you can.
