Appeal No. 1999-2640
Application 08/918,267
in Fig. 14.32 of Foley or the associated text relating to this
figure (Br7).
Figure 14.32 of Foley is directed to filtering over an
array of supersampled (supersampling is taking more than one
sample for each pixel and combining them, Foley, p. 620)
values for the purpose of antialiasing (i.e., reducing the
jagged or stairstep appearance of lines due to the finite size
of the pixel). Filtering combines the samples to create a new
sample; note that the 11x11 block is reduced to a 5x5 block.
Filtering has no apparent direct connection to generating a
texture value. In any case, Foley lacks the specific steps of
claim 1.
Appellant argues that the Examiner errs in finding that
Thier shows line segments in different planes for texture
mapping in the abstract, that the Examiner provides no basis
for combining the references, and that Thier does not cure the
deficiencies of Kato (Br6).
The Examiner responds that Thier shows line segments in
different planes for texture mapping in its abstract "by
virtue of folding lines in different directions, hence planes
creating patches, i.e. texture" (EA6).
