two collada object colliding

I am trying to use Ray intersect to find out if 2 collada object collide. But so far no success :(

my code http://jsfiddle.net/XqQzF/

        object.updateMatrix();

        // ray
        var f_vector = new THREE.Vector3( 0, 0, -1 );
        var b_vector = new THREE.Vector3( 0, 0, 1 );
        var l_vector = new THREE.Vector3( -1, 0, 0 );
        var r_vector = new THREE.Vector3( 1, 0, 0 );

everytime i use something its removed from the newest three.js revision. Can you help me on the way ?

Solution

  • I recently update my three.js examples collection to be compatible with the latest version (v56 at time of writing), and this includes an example of collision detection. Check out http://stemkoski.github.com/Three.js/Collision-Detection.html (see http://stemkoski.github.com/Three.js/#collision-detection for instructions).

    The main difference in your case will be choosing a central point of your model as an origin point for the rays, and choosing a set of vertices of your model to use as endpoints for the rays, as rays are what is used for collision detection.

    Hope this helps!
