Function ray_march 

Source 
pub fn ray_march<S: Sdf>(
    sdf: &S,
    origin: [f64; 3],
    direction: [f64; 3],
    max_steps: u32,
    max_t: f64,
    surf_eps: f64,
) -> RayMarchResult
Expand description

March a ray defined by origin + t * direction through an SDF.

  • max_steps – step budget.
  • max_t – maximum travel distance.
  • surf_eps – surface-hit threshold.

Uses the sphere-tracing algorithm (Hart 1996).
