Struct ImplicitSphere 

pub struct ImplicitSphere {
    pub center: [f64; 3],
    pub radius: f64,
}

Signed distance function for a sphere.

SDF(p) = |p − center| − radius

Fields

center: [f64; 3]

Center of the sphere.

radius: f64

Radius of the sphere.

Implementations

impl ImplicitSphere

pub fn new(center: [f64; 3], radius: f64) -> Self

Create a new implicit sphere.

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

Signed distance from point p to this sphere.

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

Outward unit normal at point p.

pub fn hessian(&self, p: [f64; 3]) -> [f64; 9]

Hessian of the SDF at point p (3×3 flat row-major).
