Struct Plane 

pub struct Plane {
    pub normal: Vec3,
    pub distance: Real,
}

A plane defined by a normal and signed distance from origin.

Fields

normal: Vec3

Outward-facing normal (should be normalized).

distance: Real

Signed distance from the origin along the normal.

Implementations

impl Plane

pub fn new(normal: Vec3, distance: Real) -> Self

Create a new plane.

pub fn signed_distance(&self, point: &Vec3) -> Real

Signed distance from a point to this plane.

pub fn from_points(a: &Vec3, b: &Vec3, c: &Vec3) -> Option<Self>

Create a plane from three non-collinear points.

The normal is computed as (b - a).cross(c - a) normalized. Returns None if points are collinear.

pub fn project_point(&self, point: &Vec3) -> Vec3

Project a point onto this plane.

pub fn reflect_point(&self, point: &Vec3) -> Vec3

Reflect a point across this plane.

pub fn classify_point(&self, point: &Vec3, tolerance: Real) -> i32

Classify a point relative to this plane.

Returns positive if the point is on the front side, negative on the back side, or zero if it lies on the plane (within tolerance).

impl Plane

pub fn intersect_ray(&self, ray: &Ray) -> Option<Real>

Ray–plane intersection returning the hit t parameter.

Identical to Ray::intersect_plane but callable directly on a Plane.

Trait Implementations

impl Clone for Plane

fn clone(&self) -> Plane

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Plane

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

Formats the value using the given formatter.
