I think you're on the right track with POGL. It's the most actively maintained of the Perl-OpenGL bindings. Check out the examples directory that comes with the distribution.

If you're starting from zero with OpenGL, I can tell you that it's just a simple state machine. You tell it where things are in the universe, and it draws them while you're telling it to. Whatever the current drawing color, lighting settings, model-view matrix, etc., it just does what you tell it to according to its current state.

Using the glu* commands to draw shapes is very easy. Just remember to set up things first (color, light, etc.) before calling them.

Couple quick tips:

• Always draw in double-buffered mode. This means that you have 2 buffers: one that's being shown in the window, and the other that you're drawing on. When you're done drawing, you swap the buffers and what you just drew shows up on the screen.
• The Perl binding to OpenGL is very similar to OpenGL's C API. This means you can read OpenGL docs and tutorials, and very easily convert the code samples to work in your Perl programs.
