cgmath frustum culling

Small frustum culling crate meant to be used alongside the cgmath crate.

Usage

extern crate cgmath;
extern crate cgmath_culling;

use cgmath::{PerspectiveFov, Rad};
use cgmath_culling::{FrustumCuller, Intersection};

let per = PerspectiveFov { fovy: Rad(3.1415_f32 / 2.0),
                           aspect: 1.0,
                           near: 0.1,
                           far: 100.0 }.into();

let culling = FrustumCuller::from_perspective_fov(per);

match culling.intersect_aab(Vector3::new(0.0, 0.0, -7.0), Vector3::new(1.0, 1.0, -5.0)) {
    Intersection::Inside  => println!("I'm inside"),
    Intersection::Outside => println!("I'm outside"),
    Intersection::Partial => println!("I'm partially inside"),
}
