cgmath视锥剔除

一个小型的视锥剔除crate，旨在与cgmathcrate一起使用。

使用方法

extern crate cgmath;
extern crate cgmath_culling;

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

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

let culling = FrustumCuller::from_perspective_fov(per);
let bounding_box = BoundingBox::from_params(Vector3::new(0.0, 0.0, -7.0), Vector3::new(1.0, 1.0, -5.0));

match culling.test_bounding_box(bounding_box) {
    Intersection::Inside | Intersection::Partial => println!("I'm Inside!!!"),
    Intersection::Outside => println!("I'm Outside"),
}
