Usage

Sample usage to build a perspective camera view-projection matrix:

use core::f32::{consts::PI, INFINITY};
use munum::{transform, vec3};

let eye = vec3(0_f32, 2., 0.);
let target = vec3(0., 0.6, 0.);
let up = vec3(0., 0., -1.);
let view = transform::look_at(eye, target, up);

let proj = transform::perspective(2., PI/2., 1., INFINITY);

let view_proj = proj * view;
