Abstract
Coarse piecewise linear approximation of surfaces
causes undesirable polygonal appearance of silhouettes. We
present an efficient method for smoothing the silhouettes of
coarse triangle meshes using efficient 3D curve reconstruction
and simple local re-meshing. It does not assume the availability
of a fine mesh and generates only moderate amount of additional
data at run time. Furthermore, polygonal feature edges are also
smoothed in a unified framework. Our method is based on a novel
interpolation scheme over silhouette triangles and this ensures
that smooth silhouettes are faithfully reconstructed and always
change continuously with respect to continuous movement of
the view point or objects. We speed up computation with GPU
assistance to achieve real-time rendering of coarse meshes with
the smoothed silhouettes. Experiments show that this method
outperforms previous methods for silhouette smoothing.
