Struct Plane3 

pub struct Plane3 {
    pub normal: [f64; 3],
    pub offset: f64,
}

An infinite plane in 3D: n·x = d.

Fields

normal: [f64; 3]

Plane normal (unit vector).

offset: f64

Plane offset: d = n·p for any point p on the plane.

Implementations

impl Plane3

pub fn new(normal: [f64; 3], offset: f64) -> Self

Create from normal and offset.

pub fn from_points(a: [f64; 3], b: [f64; 3], c: [f64; 3]) -> Self

Create from three points.

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

Signed distance from point to plane (positive on normal side).

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

Project a point onto the plane.

pub fn intersect_ray(&self, ray: &Ray3) -> Option<f64>

Intersect ray with plane. Returns parameter t or None if parallel.

pub fn intersect_segment(&self, a: [f64; 3], b: [f64; 3]) -> Option<[f64; 3]>

Intersect a line segment (a → b) with the plane. Returns the intersection point or None.
