Abstract
In recent years, several techniques have been proposed
for automatically producing line-art illustrations. In this
paper a new non photo-realistic rendering scheme for
triangulated surfaces is presented. In contrast to prior
approaches with parametric surfaces, there is no global
parameterization for triangle meshes. So a new approach is made
to automatically generate a direction field for the strokes.
Discrete curvature analysis on such meshes allows to estimate
differential parameters. Lines of curvature are then
constructed to be used as strokes. Using triangulated surfaces
allows to render aesthetically pleasing line drawings from a
huge class of models. Besides, experiments show that even real
time visualization is possible.
