Struct CylinderSDF 

pub struct CylinderSDF {
    pub radius: f64,
    pub half_height: f64,
}

Infinite cylinder SDF along the Y axis centred at the origin.

• radius — cylinder radius
• half_height — half-length along the Y axis

Example

use oxiphysics_geometry::implicit_surfaces::{ImplicitSurface, CylinderSDF};
let c = CylinderSDF::new(1.0, 2.0);
// Point on lateral surface, within height bounds
let d = c.eval([1.0, 0.0, 0.0]);
assert!(d.abs() < 1e-12);

Fields

radius: f64

Radius of the cylinder.

half_height: f64

Half-height along the Y axis.
