Struct vek::geom::repr_c::Ray [−][src]
Expand description
3D ray, represented by a starting point and a normalized direction vector.
Fields
origin: Vec3<T>
The ray’s starting point.
direction: Vec3<T>
The ray’s direction. Methods expect it to be normalized.
Implementations
Creates a Ray
from a starting point and direction.
This doesn’t check if direction
is normalized, because either you know it is, or
it isn’t and maybe it doesn’t matter for your use case.
Tests if this ray intersects the given triangle, returning the distance from the ray’s origin along its direction where the intersection lies.
If the returned value is Some(x)
where x < EPSILON
, then you should
assume there was a line intersection, NOT a ray intersection.
This uses the Möller–Trumbore intersection algorithm.
