Together with Kwan-Liu Ma, I have
been working on methods for facilitating the visualization and manipulation
of large 3D unstructured meshes. Our approach is based on identifying and
displaying only the most perceptually relevant edges in the mesh.
This research is summarized in our paper
"Extracting Feature Lines from 3D Unstructured Grids"
proceedings of
Visualization '97, pp. 285-292
(6M pdf).
