Snow Sculpting in Breckenridge, Colorado
January 16-20, 2001, at the 11th annual
Breckenridge International Snow Sculpture Championship,
Stan Wagon (Team Captain), Robert Longhurst (Artist), John Bruning,
and Dan Schwalbe will be sculpting a snow version of an original design of
Robert Longhurst. The title of the
snow sculpture is White Narcissus.
Stan Wagon showed Matthias Weber photographs of this sculpture in October 2000, and asked him whether he could come up with a parameterization of this surface.
The sculpture looked quite complicated; from a single photograph it is even hard to say how many boundary curves there are. Also, it seemed as if there were two straight lines on the surface, a very useful thing when one is looking for a parameterization of a minimal surface. You can find the somewhat surprising results of Matthias's investigations here.
