Struct TorusSDF 

pub struct TorusSDF {
    pub major_r: f64,
    pub minor_r: f64,
}

Torus SDF centred at the origin, lying in the XZ plane.

• major_r — distance from the torus centre to the tube centre
• minor_r — radius of the tube

Example

use oxiphysics_geometry::implicit_surfaces::{ImplicitSurface, TorusSDF};
let t = TorusSDF::new(2.0, 0.5);
// Point on the outer equator of the torus
let d = t.eval([2.5, 0.0, 0.0]);
assert!(d.abs() < 1e-12);

Fields

major_r: f64

Major radius (distance from origin to tube centre).

minor_r: f64

Minor radius (tube radius).
