Summary:
Nishino et al. designed a 3D object modeling system that uses stereoscopic glasses, CyberGloves, and polhemus trackers.
The system allows the creation of superellipsoids that can have smooth or squarish parameters. These primitive shapes can be bent, stretched, twisted, and merged with other shapes. Hand postures control these actions, such as grasping and pointing. Virtual hands are displayed on a 200-inch arched screen, along with the object, in stereoscopic mode. The virtual hands allow the user to easily see where they can touch and modify the 3D model.
The authors tested the system by having users attempt two types of objects: symmetric and asymmetric. The symmetric object was a bottle, and the asymmetric object was a teapot.
Creation of the objects took up to 120 minutes. The size of the stored objects was much less than a competing program, Open Inventor.
Discussion:
For a paper in 1998, this was a pretty advanced system and seemed to offer some benefits over other systems. I would have liked to have seen feedback from the users, though, since I'm not sure how hard the system is to use.

As far as usability goes, it seems like you'd have to be pretty good at sculpting to get any decent results. But if you were good at sculpting, just use clay since it's "recyclable" by just adding water, and you're not constrained to superellipsoids.
