No, Fasttraxx, not by name, but they should have, because your understanding of materials, especially marble, is considerably more advanced than what the scientists are capable of at the moment. On the other hand, they are beginning to realize how complicated aging materials is, and have some interesting algorithms, though the bronze they picture as aging and weathering on the Buddha is strictly programmatic. In the mathematical section by Ian Stewart there is also a section on virtual sculpture with some beautiful 3-D saddle objects made by an artist that the mathematicians are just now trying to understand. And the cover of the magazine, which they call a "painting", looks to the discerning eye as if it were definitely sketched out a few times in Bryce. At any rate, the two academics who wrote the article, which is fairly thorough, could definitely use your help. If they are successful in some of the algorithms they are trying to develop, some very useful plugins or standalones might be possible. Thanks for all the magnificent materials.
