    simpleVector front=obj.getZAxis();
     simpleVector fix_front=null;
    fix_front=obj.checkForCollisionEllipsoid(front,ellipsoid, 5);
    if(front.equals(fix_front)==true)
    {
       source.setTransparency(-1);//source will see
    }
    else if(front.equals(fix_front)==false)
    {
       source.setTransparency(0);//source will disappear
    }
   source.translat(fix_front);
}







my problem:
when ellipsoid=(10,10,10) or ellipsoid=(100,100,100);
their checkcollition's distance was the same,just same unit away between source and target,then source be disappear.

so how to change checkcollition's distance?whatever i do with ellipsoid,but the distance just the same.

Try to increase http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Config.html#collideOffset (http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Config.html#collideOffset) to something like 1000 or so.
