Trait Implementations§

Source§

impl Sdf for SdfOffset

Source§

fn distance(&self, p: [f64; 3]) -> f64

Signed distance from point p to the surface.
Source§

fn gradient(&self, p: [f64; 3]) -> [f64; 3]

Gradient of the SDF at p (numerical central differences by default).
Source§

fn normal(&self, p: [f64; 3]) -> [f64; 3]

Outward unit normal at p (normalised gradient).
