We reverse.
BACKGROUND
The invention relates to a method and apparatus for
generating a texture for line segments. As shown in Fig. 1,
a plurality of three-dimensional line segments are input at 1
(defined by a mathematical function or by use of a graphics
input device, specification, p. 7, lines 3-6), line
coordinates within the coordinate range are generated at 5
(i.e., the line segment is converted into a two-dimensional
coordinate value of the initial or terminal point of each line
segment, specification, p. 5, lines 17-24), the line
coordinates are used to generate a position value for each
position within the coordinate range at 2 and 6 (i.e., the
straight line is rasterized into a sequence of point data),
and a texture value is generated for each position within the
coordinate range at 7 and 3 (i.e., an evaluation value is
applied for each point of the point sequence, Figs. 2-5).
