abstract = {We present an effective method for automatically selecting the
appropriate scale of shape features that are depicted when
rendering a 3D mesh in the style of a line drawing. The method
exhibits good temporal coherence when introducing and removing
lines as needed under changing viewing conditions, and it is fast
because the calculations are carried out entirely on the graphics
card. The strategy is to pre-compute a sequence of filtered
versions of the mesh that eliminate (via a signal processing
technique) shape features at progressively larger scales. Each
mesh in the sequence retains the original number of vertices and
connectivity, providing a direct correspondence between meshes.
The mesh sequence is loaded onto the graphics card, and at
run-time a vertex program interpolates positions and curvature
values between two of the meshes, depending on distance to the
camera. A pixel program then renders silhouettes and suggestive
contours to produce the line drawing. In this way, fine shape
features are depicted over nearby surfaces, while appropriately
coarse-scaled features are depicted over more distant regions.},
