  1. Research Interests By David Whittinghill

  2. Who I am • Professional programmer since 1997 • Technical subject areas • Simulation • Computer graphics/UI design • Enterprise application architecture/development • Database design • IT/Web programming/design • Multimedia (Web, CD-ROM) • Subject domains • AI • Pharmaceuticals • Machine vision

  3. Who I am • Master’s of Science - Purdue, West Lafayette 2003 • Enterprise Application Development • Computer Graphics • Doctor of Philosophy - Purdue, West Lafayette 2008 (expected) • Physically-based rendering • Virtual reality

  4. Overview • Scientific Visualization • Simulation and Modeling • Physically-Based Rendering • High Performance Computing • Distributed Applications • Agent-Based Simulation • Virtual Reality • Games • Machine Vision • User Interface Development

  5. Dissertation Modeling Visible-spectrum EM Radiation in a 3-Dimensional Space Massa, 2005

  6. And this is important…why?...

  7. Dissertation Introduction • In 2004, President George W. Bush announced the US will go to Mars. • A one way trip to Mars will take 6 months. • How does one store a year’s worth of food and oxygen on a spacecraft?

  8. Dissertation Introduction • You don’t. • Plants growing in ALS (Advanced Life Support) modules will convert carbon dioxide and provide food. • Prototyping the ALS modules is slow and expensive. • Instead, designs will be tested as a software simulation prior to construction.

  9. Dissertation • Create a model of the light field that surrounds the plants in an ALS. • This will allow designers to make a better estimate of the amount of radiance existing at any spatial coordinate in the chamber. Massa, 2005

  10. Dissertation • Ray tracing • Full spectrum light modeling (near full: 2nm bins) • BRDF (Bi-directional Reflectance Distribution Function) • BTDF (Snell’s Law, ABM) • Stochastic Modeling (Monte Carlo) • ABM (Algorithmically Based Model)

  11. Research Interests • HPC • The transmission model used could expand the variable count dramatically, HPC could help. • Virtual Reality • Can be used to extend application interface. • Distributed Applications • Could extend use of application to other facilities.

  12. Research Interests • Dissertation touches on: • Scientific Visualization • Simulation and Modeling • Physically-Based Rendering • Agent-Based Simulation

  13. Other Interests • Games and Ray Tracing • Intel is pushing hard to give its extra cores something to do. • Real-time ray tracing is the holy grail of rendering. • Machine Vision and UI Development • There is interesting research uniting the two. • Games and VR • This is underutilized territory. Commercial potential! Shirley, 2006
