pub fn default_perspective(width: f32, height: f32) -> (Mat4, Mat4)Expand description
Returns the projection and view matrices for a camera with default perspective.
The default projection and view matrices are defined as:
use glam::*;
let width = 800.0;
let height = 600.0;
let aspect = width / height;
let fovy = core::f32::consts::PI / 4.0;
let znear = 0.1;
let zfar = 100.0;
let projection = Mat4::perspective_rh(fovy, aspect, znear, zfar);
let eye = Vec3::new(0.0, 12.0, 20.0);
let target = Vec3::ZERO;
let up = Vec3::Y;
let view = Mat4::look_at_rh(eye, target, up);
assert_eq!(renderling::camera::default_perspective(width, height), (projection, view));
