Hi, I was wondering if it was possible in OpenGL to do a single draw call using different indice sets for each of the vertex arrays e.g: vertices, normals, etc. So I'd pass OpenGl these: verticesIndices, normalIndices. I hope I explained that clear enough. I think Direct3D and Open Scene Graph can do this. Thanks.

With enough acrobatics in GL3.2, it's possible.

But OpenGL != DX. Draw-calls in GL are very lightweight, funky optimizations are to be done if you know what you're doing :)
