Struct SphereSDF 

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

Sphere SDF: f(p) = |p − center| − radius.

Example

use oxiphysics_geometry::implicit_surfaces::{ImplicitSurface, SphereSDF};
let s = SphereSDF::new([0.0, 0.0, 0.0], 2.0);
assert!((s.eval([2.0, 0.0, 0.0])).abs() < 1e-12);

Fields

center: [f64; 3]

Centre of the sphere.

radius: f64

Radius of the sphere (must be positive).
