Struct de_pathing::geometry::RayProjection

pub(crate) struct RayProjection {
    parameter: Option<f32>,
    endpoint_a_side: SimpleSide,
}

Projection of a ray onto a line segment.

Fields

parameter: Option<f32>

endpoint_a_side: SimpleSide

Implementations

impl RayProjection

pub(crate) fn calculate(ray: Ray, target: Segment) -> Self

pub(crate) fn new(parameter: Option<f32>, endpoint_a_side: SimpleSide) -> Self

pub(crate) fn parameter(&self) -> Option<f32>

A value between 0 and 1 (inclusive). The parameter is None if the ray does not intersect the segment.

The intersection point is given by `segment.a + (segment.b - segment.a)

• parameter`.

pub(crate) fn endpoint_a_side(&self) -> SimpleSide

Side of endpoint a of the segment relative to the ray.

In the case that endpoint lies on the line given by the ray, it is assumed that endpoint a lies on the opposite site than endpoint b.

Trait Implementations

impl Clone for RayProjection

fn clone(&self) -> RayProjection

Returns a copy of the value.

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

Performs copy-assignment from source.
