in Fig. 6B (FR3). However, Fig. 6B merely shows a
two-dimensional image (texture image or texture map) to be
mapped onto the surface of an object. The rectangular grid
pattern is used, instead of pictures like Figs. 16.25(a)-(f)
of Foley, so that the mapping transformation is clear; note
how the right angles and equal sides of the grid squares
become distorted when mapped to an object as in Fig. 6C. Even
if the lines in Fig. 6B were line segments, they are not "in
differing planes to provide a three-dimensional appearance,"
as claimed because Fig. 6B is a two-dimensional coordinate
system as evidenced by Fig. 7A. Moreover, we do not
understand the Examiner's assertion that Fig. 6B shows
generating line points located on line segments. Claim 1
calls for generating "line coordinates," i.e., coordinates of
the line. As disclosed, these coordinates may correspond to
the initial or terminal point of each line segment
(specification, p. 5, lines 17-24). A "coordinate" is a
defined as "any of a set of numbers used in specifying the
location of a point on a line, on a surface, or in space,"
Webster's New Collegiate Dictionary (G. & C. Merriam Co.
1977). The Examiner has not explained, and it is not apparent
