TITLE:
Orca: A Visualization Toolkit for High-Dimensional Data

ABSTRACT:
The main goal of the Orca project is to make interactive and dynamic graphics
programming accessible to researchers from many different backgrounds. It
arises from years of development of XGobi, and progresses this implementation
by taking advantage a new programming language: java. The object-oriented
nature of java is exploited to open up the data pipeline allowing developers
greater flexibility and control over their applications. The Orca framework
separates different aspects of data processing and rendering into segments of a
pipeline.  New types of dynamic graphics that adhere to a few simple Orca
design requirements can be easily integrated with existing pipe sections.  This
integration will allow access to sophisticated linking and dynamic interaction
across all Orca view types. Orca pipes can be called from data analysis
packages such as omegahat or R.

This talk will include discussion of data pipeline ideas, the pipes available
in Orca, demonstration of several applications, and plans for future work.  The
web page for the project is pyrite.cfas.washington.edu/orca.

Joint work with Peter Sutherland (Affymetrix), Thomas Lumley (NRCSE, U.
Washington), Anthony Rossini (Biostat, U. Washington), Zach Cox, Julie
Dickerson (Electrical Engineering, ISU). Funding to initiate the collaboration
was provided by NRCSE, and continued funding has been provided by an ISU SPRIG
grant, and the CFAR, UW, as well as NRCSE.
