[comp.graphics.visualization] Bay Area Siggraph mtg: Artistic Devices & Photorealism in Sci. Vis.

nebulus@well.sf.ca.us (Bruce McDiffett - no good deed goes unpunished) (11/23/90)

Because some Bay Area sites get their news feeds from outside the BA,
I'm reposting the announcement of our November meeting. - Bruce

The Bay Area chapter of ACM/Siggraph - the Special Interest Group on 
Computer Graphics and Interactive Techniques - invites everyone to
attend its November meeting:


		  ARTISTIC DEVICES AND PHOTOREALISM

		     IN SCIENTIFIC VISUALIZATION


			      Marc Levoy
		     Computer Science Department
			  Stanford University


				8:00 pm
			    Tuesday, Nov. 27
			 Xerox PARC Auditorium
			 3333 Coyote Hill Road
			     Palo Alto, CA


The scientific and medical communities are deeply divided over the 
merit of incorporating artistic devices and photorealism into data 
visualizations.  Techniques such as metallic shading, shadow-
casting, surface and solid texturing, and selective defocusing are 
common in hand-drawn illustrations, but their use in computer-
mediated data exploration is not widely accepted.  Marc will argue 
that these techniques, if properly used, improve spatial 
comprehension and hence the utility of computer-generated 
visualizations.  To illustrate his argument, Marc will describe 
the application of volume rendering - a technique for displaying 
sampled 3D data - to two problems: 1) interpretation of molecular 
electron density maps; and 2) planning of radiotherapy for cancer 
patients.


Marc Levoy is an assistant professor of computer science and 
electrical engineering at Stanford University.  He holds an M.S. 
degree in computer graphics from Cornell University and a Ph.D. in 
computer science from the University of North Carolina.  Levoy 
headed the Hanna-Barbera Studios Computer Animation project for 
several years and has chaired two courses at Siggraph on computer 
animation.  His current research interests include scientific 
visualization, volume rendering, medical imaging, and molecular 
graphics.


* Directions to Xerox

From 280, take the Page Mill Road exit.  Take Page Mill 1 mile 
east to Coyote Hill Road.  Follow Coyote Hill 1/2 mile, and Xerox 
will be on the left.  Follow the signs to the auditorium and 
visitor parking area.

From 101, take the Oregon Expressway exit west 2 miles to El 
Camino Real.  Oregon Expressway becomes Page Mill Road at El 
Camino Real.  Follow Page Mill Road 1.7 miles to Coyote Hill Road 
and turn left.  Go 1/2 mile and Xerox will be on the left.  Follow 
the signs to the auditorium and visitor parking area.

The auditorium entrance is at the north end of the building, at 
the bottom of the stairs.
