opengl-4

I would like to know the attribute locations inside fixed pipeline (no shader attached) for nVidia OpenGL drivers: glVertex = 0 glColor = 3 glNormal = ? glTexCoord = ? glMultiTexCoord 0..7 = ? glSecondaryColor = ? glFog = ? Empirically I found the Vertex and primary Color locations but still will be nice to know them all. If you want to know why, then for compatibility reasons and even for GLSL debugging (just to see if I pass the correct data to correct locations when shader not works yet) and so on ... Outside of NVIDIA drivers, this does not work (reliably). Compliant drivers will only

I am an armature in OpenGl and for this reason I am seeking to learn only modern OpenGl the 4.x stuff. Once I had completed basic tutorials (rotating cubes for example.) I decided I would try and create a voxel based program dealing solely with cubes. The goals of this program was to be fast, use limited CPU power and memory, and be dynamic so the map size can change and blocks will only be drawn if in the array it says the block is filled. I have one VBO with the vertices and indexes of a cube built out of triangles. At the beginning if the render function I tell OpenGl the shaders to use and
