Struct BoxSDF 

pub struct BoxSDF {
    pub half_extents: [f64; 3],
}

Axis-aligned box SDF centred at the origin.

half_extents[i] is the half-size along axis i.

Example

use oxiphysics_geometry::implicit_surfaces::{ImplicitSurface, BoxSDF};
let b = BoxSDF::new([1.0, 2.0, 3.0]);
// A point on a face
let d = b.eval([1.0, 0.0, 0.0]);
assert!(d.abs() < 1e-12);

Fields

half_extents: [f64; 3]

Half-extents along each axis.
