SUMMARY:Brown bag: Steve Marschner
DESCRIPTION:Title: Fibers and the appearance of materials\nSpeaker: Steve
	 Marschner\nAbstract: Many beautiful materials derive their appearance
	 and mechanical properties from a microstructure composed of fibers. This
	 is true of hair\, fur\, cloth\, and even wood.  This talk will discuss
	 recent research on modeling\, simulation\, and rendering that applies to
	 these materials\, which shares the theme of modeling and measuring
	 structure to get the right appearance.  In hair\, the key problem is to
	 model the complex patterns formed by light interacting with individual
	 transparent fibers\, which are caused by the small-scale structure of
	 the fibers and their surfaces.  Smaller fibers packed together into a
	 solid give rise to the varied appearance of wood\, which reflects the
	 three-dimensional anatomy trees\, leading to distinctive grain and
	 figure on cut and polished surfaces.  The final topic is a new technique
	 for realistically rendering textiles using volume data originating from
	 micro CT scans of small samples of cloth.
