          Appeal No. 96-2994                                                           
          Application 08/282,413                                                       


          of simplification noted by Fuchs, however, do not suggest the                
          determination of a second partitioning plane only when the                   
          first or second object moves                                                 
          across a first partitioning plane which is defined as being                  
          between the two objects.                                                     
          Claims 1 and 14 require that action take place based                         
          on a specific type of relative movement between a first and                  
          second object in a virtual reality environment.  The movement                
          recited in the claims has nothing to do with the movement of                 
          the observer within the virtual reality environment.  Only a                 
          specific type of movement of one object within the environment               
          with respect to another object within the environment leads to               
          the determination of a second partitioning plane as recited in               
          claims 1 and 14.  Such a determination is not suggested by the               
          combined teachings of Corthout and Fuchs.                                    





          Since we agree with appellants that the combined                             
          teachings of Corthout and Fuchs do not teach or suggest the                  
          invention of independent claims 1 and 14, we do not sustain                  
                                          10
