What is on line 665 of POModel.m?

Where is `getLightSpace' defined and how is it used?

This error is indicative of using a function before its been
declared.  The compiler is warning that this method needs to
be supplied somewhere and if it can't be found at runtime
then the app will probably core dump.

You set lightModel = theLightSpace, right? That is:
             ^^^^^

   -(void)setLightModel: (id) l { 
       lightModel = l; 
       return ; 
   }


What is this lightSpace?  Was this a typo?
                  ^^^^^

My apologies if I misunderstood what you had written.

Ken.
