Hi,

Hopefully someone knows enough about toxiclibs to help me out here...

I am trying to hide faces on a mesh that are hidden from the current camera position (obscured by some other face on the mesh). To do this I am trying to implement the intersectsRay method in the toxiclibs TriangleMesh class. However, when I retrieve the intersection pos vector from isectData3d it just spits out a bunch of points on a plane, not intersection points with the mesh. I have tried reversing the ray, which gives me some very wacky points - but still not intersection points on the mesh. Heres the function I am using:

1.  public void updateDisplayFaces(Vec3D fromPos){
            //loop through faces
            for(int i = 0;i<bounds.faces.size();i++){
                WEFace f = (WEFace) bounds.faces.get(i);
                //create an intersector between face center and camera pos
                Vec3D target = f.getCentroid().copy();
                Ray3D isec = new Ray3D(fromPos,target);
                //intersect the mesh
                if( bounds.intersectsRay(isec)){
                    IsectData3D data = bounds.getIntersectionData();
                    if(data.isIntersection){
                        Vec3D ipos = data.pos.copy();
                        parent.stroke(255);
                        parent.point(ipos.x,ipos.y,ipos.z);
   
                    }
                }
            }
        }

Any suggestions of help with using these intersection methods? I dont want to have to use TriangleIntersector3d because looping through all the mesh faces gets very slow.

Thanks
