Struct SmoothUnionSDF 

pub struct SmoothUnionSDF<A, B> {
    pub a: A,
    pub b: B,
    pub k: f64,
}

Smooth (C¹) union of two implicit surfaces using polynomial blending.

The parameter k controls the blend radius. Larger k gives smoother transitions.

Fields

a: A

First operand.

b: B

Second operand.

k: f64

Blend radius (must be > 0).

Implementations
