Struct CsgDifference 

pub struct CsgDifference {
    pub a: Box<dyn ImplicitSurface>,
    pub b: Box<dyn ImplicitSurface>,
}

CSG difference: region inside a but outside b.

SDF = max(sdf_a, -sdf_b).

Fields

a: Box<dyn ImplicitSurface>

The base shape.

b: Box<dyn ImplicitSurface>

The shape to subtract.

Implementations

impl CsgDifference

pub fn new(a: Box<dyn ImplicitSurface>, b: Box<dyn ImplicitSurface>) -> Self

Create a new difference.

Trait Implementations

impl ImplicitSurface for CsgDifference

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

Signed distance from p to the nearest point on the surface.

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

Gradient of the SDF at p (should be approximately unit-length on the surface).
