George W. Hart will bring examples and show slides
of some of his mathematically informed sculptures.
These include works made of metal, wood, acrylic,
paper, CDROMs, floppy disks, forks, knives, spoons,
etc. Also shown will be three-minute videos of the
assembly of two recent commissions: a six-foot sculpture
constructed from 642 CDROMs in the Computer Science
building at U.C. Berkeley, and a five-foot sculpture
constructed at a community "barn raising"
event, at the Northport NY Public Library. For examples
of Hart's work, see http://www.georgehart.com/.
Each is founded on a mathematical structure of some
type. Many involve novel algorithms, Rapid Prototyping
techniques, (Solid Freeform Fabrication) or laser-cutting
to create very accurate components for assembly.
extended face planes of symmetric polyhedra form
a set of interconnected canvases that can be used
as the basis for a wide range of sculptural forms.
A special-purpose software tool is described which
allows the user to select families of such planes,
to draw within them, to maintain constraints concerning
points lying on their intersections, to view and
modify the results interactively in real time, and
to output the result for production either as 3D
rapid prototyping or 2D laser-cutting, etc. A range
demonstrate the versatility of the approach. One
example will be constructed on campus as a large
group assembly project from laser-cut wooden components.
