TRUCHET CURVES AND SURFACES
*
*An LKL Maths-Art seminar by
Cameron Browne (SWiSHzone.com, Sydney)
**Tuesday 11 March, 6.00 - 7.30pm

*Three centuries ago, French clergyman Sebastien Truchet made a
combinatorial study of a simple square tile that produced attractive
patterns when arranged symmetrically within a grid. Two decades ago, a
modified version of this tile was found to produce visually interesting
results even when tiled randomly. This modified form has since become
popularly known as the *Truchet tile* and provided a ready motif for many
graphical works.

This talk will briefly cover the Truchet tile's history, basic construction,
and its use in art, games and puzzles. *Truchet contours* (closed curves
within a tiling) will be discussed, and a method presented for automatically
filling a given area with a single Truchet contour, based upon a spanning
tree of the underlying grid. Rules for adapting this method to
multiresolution grids allow the development of multiresolution Truchet
tilings suitable for artistic halftoning. The general concept will be
extrapolated to three dimensions and the construction of Truchet surfaces
discussed.

*Cameron Browne [www.cameronius.com] is an Australian software engineer
interested in board games and graphics.
