How to detect the point of intersection of a Line and a Triangle (3D)

There is some information but I couldn't figure it out: http://softsurfer.com/Archive/algori...gment-Triangle

How can I detect if a line intersects with a triangle ? And how can I detect the point of intersection in AS3 ?

That site looks like it gives a pretty thorough explanation of what needs to be done.

I assume you're trying to implement a function like this

Code:

---

import flash.geom.Vector3D;

function intersectTriangleLineSegment(Vector3D V0, Vector3D V1, Vector3D V2, Vector3D P0, Vector3D P1) : Vector3D
{
        var u = V1.subtract(V0);
        var v = V2.subtract(V0);
        var n = u.crossProduct(v);

        // ....more stuff goes here

        return null;
}

What part is giving you trouble?

I solved my problem with an other technique. But your post may help others who google search this technique.
