When i use world.removeObject(obj),and later use world.addObject(obj),the obj is still there.
i thought removeobject() will clear object from memory,in fact i am wrong?
so,if i want to destroy obj,i just use,
obj.clearobject();
obj.clearrotation();
obj.cleartranslation();
obj=null;
is that right?
in a shorting say,if i want destroy a object3D,which method will free memory,and really set the obj clear?
