Struct CsgSmoothDifference 

Source 
pub struct CsgSmoothDifference {
    pub a: Box<dyn ImplicitSurface>,
    pub b: Box<dyn ImplicitSurface>,
    pub k: f64,
}
Expand description

Smooth CSG difference.

SDF = smooth_max(sdf_a, -sdf_b, k).

Fields§

§a: Box<dyn ImplicitSurface>

The base shape.

§b: Box<dyn ImplicitSurface>

The shape to subtract.

§k: f64

Smoothing factor.

Implementations§

Source§

impl CsgSmoothDifference

Source

pub fn new( a: Box<dyn ImplicitSurface>, b: Box<dyn ImplicitSurface>, k: f64, ) -> Self

Create a new smooth difference.

Trait Implementations§

Source§

impl ImplicitSurface for CsgSmoothDifference

Source§

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

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

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

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