Bug Description
Currently, every time we want to render something we have to do something like this:
glBindBuffer (GL_ARRAY_BUFFER, vertices);
glEnableVertexA
glBindBuffer (GL_ARRAY_BUFFER, colors);
glEnableVertexA
glBindBuffer (GL_ARRAY_BUFFER, texcoords);
glEnableVertexA
glDrawArrays ...
glDisableVertex
glBindBuffer (GL_ARRAY_BUFFER, 0);
With vertex array objects we can do this:
glBindVertexArray (vArray)
glDrawArrays
Much fewer calls into openGL! And much fewer expensive ones too.
