Variants

Sphere

Sphere centred at center with radius radius.

Fields

center: [f64; 3]

World-space centre of the sphere.

radius: f64

Sphere radius (must be positive).

Box3d

Axis-aligned box centred at center.

Fields

center: [f64; 3]

World-space centre of the box.

half_extents: [f64; 3]

Half-extents along each axis (width/2, height/2, depth/2).

Cylinder

Infinite cylinder (along the Y-axis) with a finite height cap.

Fields

center: [f64; 3]

World-space centre of the cylinder.

radius: f64

Cylinder radius.

height: f64

Total height (symmetric about center).

Torus

Torus whose axis is the Y-axis.

Fields

center: [f64; 3]

World-space centre of the torus.

r_major: f64

Major (ring) radius — distance from the torus centre to the tube centre.

r_minor: f64

Minor (tube) radius.

Implementations

impl SdfPrimitive

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

Evaluate the SDF for this primitive at world-space point p.

Trait Implementations

impl Clone for SdfPrimitive

fn clone(&self) -> SdfPrimitive

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SdfPrimitive

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SdfPrimitive

fn eq(&self, other: &SdfPrimitive) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
