Implementations§

Source §

impl Camera

Source

pub fn look_at( eye: [f64; 3], target: [f64; 3], world_up: [f64; 3], fov_y_deg: f64, aspect: f64, aperture: f64, focus_dist: f64, ) -> Self

Create a new perspective camera with look-at setup.

Source

pub fn generate_ray(&self, px: f64, py: f64, width: f64, height: f64) -> Ray

Generate a primary ray for pixel (px, py) in [0,W) x [0,H).

Source

pub fn generate_dof_ray( &self, px: f64, py: f64, width: f64, height: f64, lens_u: f64, lens_v: f64, ) -> Ray
