Appeal No. 1999-2640
Application 08/918,267
texture mapping and broadly shows generating a texture value
for each position on the seat back. Claim 1 does not preclude
generating a texture value for each position on the seat back
by texture mapping and claim 1 does not require use of an
evaluation function. However, since Kato lacks the earlier
steps of claim 1, it cannot satisfy this last step.
As previously noted, the Examiner seems to find that Kato
teaches generating textures as recited in claim 1, but does
not do so "by surface rendering surface color information
based on position values generated for each position" as
recited in the narrower claim 4, which is not at issue.
Nevertheless, we consider the teachings of Foley and Thier.
Appellant argues that Foley describes the use of
prefiltering before sampling, or postfiltering after sampling,
to perform anti-aliasing of a displayed image and all that
would result from Foley would be perhaps a better rendering of
the lines in the mapped picture of Fig. 6C (Br5-6). It is
argued that the Examiner is in error in asserting that Foley
teaches application of filtering to "texture generation" and
there is no illustration or discussion of texture generation
