rayTriangleParametric
fun rayTriangleParametric(ray: Ray, p0: Cartesian3, p1: Cartesian3, p2: Cartesian3, cullBackFaces: Boolean? = definedExternally): Double(source)
Computes the intersection of a ray and a triangle as a parametric distance along the input ray. The result is negative when the triangle is behind the ray.
Implements Fast Minimum Storage Ray/Triangle Intersection by Tomas Moller and Ben Trumbore.
Return
The intersection as a parametric distance along the ray, or undefined if there is no intersection.
Parameters
ray
The ray.
p0
The first vertex of the triangle.
p1
The second vertex of the triangle.
p2
The third vertex of the triangle.
cullBackFaces
If true, will only compute an intersection with the front face of the triangle and return undefined for intersections with the back face. Default value - false
