Package Exports
- ray-triangle-intersection
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ray-triangle-intersection) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
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.
