It basically reduces the entire OpenGL commands for rending an object to BindVAO -> Render, cutting out all the calls to bind each buffer and pointer separately. While this doesn't actually make much difference at the OpenGL end (the driver basically just does the other bind calls for you), it represents a huge savings in calls across that expensive ctypes <--> python bridge. -- Tristam MacDonald http://swiftcoder.wordpress.com/ -- You received this message because you are subscribed to the Google Groups "pyglet-users" group.
