متن کامل180 Wrapped Tubes
The 180 models collected in this paper are produced by sampling and wrapping point sets on tubes. The surfaces are represented as triangulated 2-manifolds and available as stlfiles from the author’s web site at www.cs.duke.edu/ edels. Each tube is obtained by thickening a circle or a smooth torus knot, and for some we use the degrees of freedom in the thickening process to encode meaningful inf...

The treatment goal is the removal of the corneal and conjunctival portion of the...
