Architects and other design professionals create presentation
graphics that intentionally avoid full realism. Successfully
automating this style of imagery fa- vorably a ects the speed and
cost of producing such illustrations. Automatically creating line
textures allows a user interactively to modify and navigate a
three- dimensional (3D) architectural scene while still
maintaining the aesthetic appeal inherent of hand-drawn
illustrations. Carefully choosing the set of lines to be drawn
allows the direct use of 3D line primitives on commodity graphics
hardware. The resulting system produces interactive drawings of
high visual quality that are free of animation artifacts such as
blurring or popping. This system also allows the level of
abstraction of the rendered scene to change dynamically.
