Appeal No.95-5026
Application 07/923,668
method for collecting and processing computer graphics polygonal
vertex data for use in high-speed graphics displays. More
particularly, the invention provides increased computer display
system performance by reducing the number of redundant calcula-
tions required in generating display data for out-the-window
simulation.
The independent claim 1 is reproduced as follows:
1. An apparatus for reducing redundant matrix trans- formation
of shared polygonal vertex data in a computergraphics system,
comprising:
means for transforming original vertex data into world
space data;
means for storing said world space data;
means for identifying a shared vertex; and
means for retrieving stored world space data corre-
sponding to said shared vertex and supplying the
retrieved world space data corresponding to said shared
vertex to a display means when said shared vertex is
identified.

Claims 1 through 9 stand rejected under 35 U.S.C. § 103 as
being unpatentable over Foley in view of Einkauf.
