Appeal No. 2005-1995
Application 09/133,741
circular, can be used for clipping. However, Sutherland (the
same Sutherland as in the Sutherland-Hodgman clipping algorithm)
contains no teaching of how clipping is to be done and does not
disclose clipping using a circular buffer.
For the reasons stated above, we find no teaching or
suggestion in either Rossin or Sutherland to use "only a single
circular buffer" to store input and output vertices of a
primitive. Since the limitation of "only a single circular
buffer" is in all claims, and since the other references are not
relied upon for this teaching, the rejections of claims 1-3,
7-18, 20-27, and 47-52 are reversed.
