[Papervision3D] Finding out of a 3D object is between camera and another object

[Peter Kapelyan]

#1 Place a null between the camera and the object you are looking at...
like
nullnode.x=(camera.x+myObj.x)/2;
nullnode.y=(camera.y+myObj.y)/2;
nullnode.z=(camera.z+myObj.z)/2;

#2 check with

nullnode.distanceTo(myObj)

the smaller the num the closer it is to the null!
Should work...untested...

Best!
-Pete
