Source 
pub struct RayMarchSdf;
Expand description

Sphere-tracing ray marcher through an SDF.

Implementations§

Source§

impl RayMarchSdf

Source

pub fn march<F: Fn([f64; 3]) -> f64>( f: &F, origin: [f64; 3], dir: [f64; 3], max_dist: f64, max_steps: usize, epsilon: f64, ) -> Option<RayMarchHit>

Sphere-trace a ray through an SDF.

Starting at origin in direction dir (unit vector), marches until the surface is hit (|SDF| < epsilon) or max_steps is reached.

Source

pub fn ambient_occlusion<F: Fn([f64; 3]) -> f64>( f: &F, pos: [f64; 3], normal: [f64; 3], samples: usize, step_size: f64, ) -> f64

Compute ambient occlusion via SDF samples along normal.
