    ray-triangle-intersection

    calculate the intersection of a ray and a triangle in three dimensions using the Möller-Trumbore intersection algorithm with culling enabled

    example

    var intersect = require('ray-triangle-intersection');
     
    var tri = [[5,5,5],[10,15,4],[15,5,3]];
    var pt = [9,5,-5];
    var dir = [0.1,0.1,0.8];
     
    console.log(intersect([], pt, dir, tri));

    output:

    [ 10.121951219512194, 6.121951219512195, 3.97560975609756 ]
    

    methods

    var intersect = require('ray-triangle-intersection')

    intersect(out, pt, dir, tri)

    Compute the intersection of the triangle tri and a ray described by a point pt and a direction dir.

    tri should be an array of [x,y,z] coordinate arrays.

    If the ray did not intersect tri, return null.

    Otherwise return and update out with the coordinates on tri where the ray intersected.
