Geometric and Solid Modeling Videos  YouTube Playlist

The geometric and solid modeling research group has produced numerous videos for various research topics. Below is a collection of videos that have been converted to AVI or MPEG format.
The videos are grouped by project.

3D Morphing

 Jack and Jill
(mpeg, 0.1 Mb)

The male head consists of 3,426 triangles. The female head consists
of 4,020 triangles. The feature nets (red) consist of 134 extremal vertices on each of the two polyhedra. All morphing trajectories are straight lines.
Donut-Cup
(mpeg, 0.2 Mb)

The doughnut consists of 4,096 triangles. The cup consists of 8,452 triangles. The feature nets (red) consist of 63 extremal vertices on each of the two polyhedra. Most morphing trajectories are straight lines, except for a few around the rim of the cup, where material was
"routed" along curved paths to avoid self-intersections. The crumpled
appearance of the morphing surface around the rim of the cup is due
to the dramatic change in surface shape between the two polyhedra, combined with a rather coarse triangulation. The shape of the folds matches the feature net portions on the doughnut which map to the
rim of the cup.
Tracy to Ruby
(mpeg, 0.3 Mb)

The human consists of 17,528 triangles. The triceratops consists of 5,660 triangles. The feature nets (red) consist of 185 extremal vertices on each of the two polyhedra. Most morphing trajectories are straight lines, except for a few around the rather flat tail, which was made to "inflate" slightly to avoid self-intersections.
