Abstract
Meaningful mesh segmentation plays a more
and more important role in various graphics applica-
tions, such as texture mapping, shape retrieval, and high-
quality metamorphosis. This paper proposes a sketch-
based interactive framework for real-time mesh segmen-
tation. With an easy-to-use tool, the user can freely seg-
ment a 3D mesh while needing little e®ort or skill. In
order to meaningfully segment the mesh, two dimen-
sionless feature sensitive metrics are proposed, which are
independent of the model and part size. We show that
these metrics give the clear physical meaning to illus-
trate discrete di®erential geometric features, such as the
curvature tensor and the curve length of gaussian im-
age. Finally, we discuss three kinds of boundary smooth-
ing methods, and present two fast topology-invariant,
geometry-invariant adjustment algorithms based on con-
vex hull features and angle features. Compared with pre-
vious methods, our method can easily achieve multi-level
segmentation in just one session.
