Vertex array Help

Hi all,

Ive been working through a copy of the “red book” trying to update my code… and i come to the topic of using arrays… great they seem like a really good idea… problem is the commands dont seem to map perfectly from the gl spec to jogl…

Has anyone got a jogl example of defining a shape using an array ?

Thanks,
J.
