AMI Days 3

Posted by Janet on July 18, 2008

Session 1
Arthur Olson and Graham Johnson spoke about the history of molecular visualization and what they do at the Molecular Graphics Lab at Scripps College. The lab produced physical models of molecules using rapid prototyping, then used these models for educational and research purposes. Some models have magnets embedded in certain areas to simulate molecular interactions. Sensors attached to molecules or used by itself could be augmented with computer graphics to represent different side chains of a molecule (see below). Different side chains can be substituted digitally, and the molecules could be held in place on screen for researchers to observe the physical fit between two molecules.

Session 2
In this lecture, Charles Falco presented many evidence showing that artists dating back to the 1430s used optics to help construct realistic details in their paintings. Evidence of optics were discovered during a collaboration between Charles Falco and David Hockney, and this discovery is now termed “The Hockney-Falco Thesis.” Visit to see clips from the documentary “David Hockney’s Secret Knowledge,” read an article, or buy the book.

Techniques Showcase and Versalius Trust Silent Auction
In the afternoon, a series of small group presentations take place simultaneously in a large room. It’s like a mini-classroom where you can sit down with experts to learn techniques in traditional medial, digital media, and to get a closer look at visualization methods presented in some of the earlier lectures. You have the option to walk between station, or sit through an entire session. A silent auction takes place in an adjacent room to raise funds for the Versalius Trust. Anyone can bring items to donate. Some items at the auction include medical books, surgical instruments, watercolor palettes, anatomy models, original artworks, and anatomy-inspired jewelries.
