Struct RayIntersection

pub struct RayIntersection<N: RealField + Copy> {
    pub toi: N,
    pub normal: Vector<N>,
    pub feature: FeatureId,
    pub uvs: Option<Point2<N>>,
}

Structure containing the result of a successful ray cast.

Fields

toi: N

The time of impact of the ray with the object. The exact contact point can be computed with: ray.point_at(toi) or equivalently origin + dir * toi where origin is the origin of the ray; dir is its direction and toi is the value of this field.

normal: Vector<N>

The normal at the intersection point.

If the toi is exactly zero, the normal might not be reliable.

feature: FeatureId

Feature at the intersection point.

uvs: Option<Point2<N>>

The textures coordinates at the intersection point. This is an Option because some shape do not support texture coordinates.

Implementations

impl<N: RealField + Copy> RayIntersection<N>

pub fn new_with_uvs( toi: N, normal: Vector<N>, feature: FeatureId, uvs: Option<Point2<N>>, ) -> RayIntersection<N>
