I was reading: Dissecting Display, Chapter 1. Hello, Triangle!.
What exactly does glEnableVertexAttribArray do? I think it enables the use of a given VBO, but I am not sure.
I thought that is what glEnableClientState(GL_VERTEX_ARRAY) did.

There is another way to specify data for a vertex attribute, the non-array way:
In this way, we specify data for only one vertex, this data will be replicated for all vertices.
To use non-array data, call glDisableVertexAttribArray.
To use array data, call glEnableVertexAttribArray.
