Ray class about three.js HOT 6 CLOSED

I'm using this. I want to put in a face -> ray intersection test, I'll probably appropriate the one from sylvester. I currently have a heightfield -> ray intersection function, but it only works for rays that are parallel to the y axis. ;D

  THREE.Ray = function ( origin, direction ) {
    this.origin = origin;
    this.direction = direction;
  }

  THREE.Ray.prototype = {
  };

  THREE.Ray.prototype.constructor = THREE.Ray;

from three.js.

I think this will work if I add getCenter() to the face class. It doesn't do a bounds test though.

intersection : function(face){
  var A = this.origin,
    D = this.direction,
    P = face.getCenter(),
    N = face.normal,

  multiplier = (N.x*(P.x-A.x) + N.y*(P.y-A.y) + N.z*(P.z-A.z)) / (N.x*D.x + N.y*D.y + N.z*D.z);
  return new THREE.Vector3([A.x + D.x*multiplier, A.y + D.y*multiplier, A.z + D.z*multiplier]);
}

from three.js.

i do face intersection tests in my new fork, the face center is not needed. Ideally I'd like to make the intersection check reusable, but everything is stowed away in ClickResolver.js right now.

Here is the commit for the 3d onclick detection / event handling:
http://github.com/mindlapse/three.js/commit/64e23a7204628998791bbd4db5d6d9355ccc1131

The code is still pretty new

Yeah. I'm struggling on what should be the right naming for all this...

Having a Ray.js as a base with the intersection methods there sounds like a good idea. Then maybe a Unproject to convert 2D coords to a 3D ray?

This is how it turned up:
