Dear interested viewers, sorry for the very low-resolution video, this is an original reel, back from 1999... Computing time was expensive, back in the days! :-) You will find running code on GitHub (see below) for demo purposes.

Publication reference:
Bourguignon D. and Cani M.-P. (2000) Controlling Anisotropy in Mass-Spring Systems. In: Proceedings of the Eleventh Eurographics Workshop on Computer Animation and Simulation, pp. 113-123, Springer-Verlag, Berlin.

Publication summary:
This paper presents a deformable model that offers control of the isotropy or anisotropy of elastic material, independently of the way the object is tiled into volume elements. The new model is as easy to implement and almost as efficient as mass-spring systems, from which it is derived. In addition to controlled anisotropy, it contrasts with those systems in its ability to model constant volume deformations. We illustrate the new model by animating objects tiled with tetrahedral and hexahedral meshes.
