` js`
var intersect = require('ray-triangle-intersection')
Compute the intersection of the triangle tri and a ray described by a pointpt 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.
With npm do:
`
npm install ray-triangle-intersection
