Selection and Feedback using a ....

Hello

Is it possible to set up a non-standard view volume for selection with multiple planes providing that it’s still convex?

Thanks.

I’ve figured out how to shape my custum frustum.
Plus the performance is increadible to beleive when running on my GeForce FX 5200.
