Dissertation Modeling Visible-spectrum EM Radiation in a 3 -Dimensional Space Massa, 2005
And this is important…why? . . .
Dissertation Introduction n 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?
Dissertation Introduction n You don’t. n Plants growing in ALS (Advanced Life Support) modules will convert carbon dioxide and provide food. n Prototyping the ALS modules is slow and expensive. n Instead, designs will be tested as a software simulation prior to construction.
Dissertation n Create a model of the light field that surrounds the plants in an ALS. n This will allow designers to make a better estimate of the amount of radiance existing at any spatial coordinate in the chamber. Massa, 2005
Dissertation n Ray tracing n Full spectrum light modeling (near full: 2 nm bins) n BRDF (Bi-directional Reflectance Distribution Function) n BTDF (Snell’s Law, ABM) n Stochastic Modeling (Monte Carlo) n ABM (Algorithmically Based Model)
Research Interests n HPC n n Virtual Reality n n The transmission model used could expand the variable count dramatically, HPC could help. Can be used to extend application interface. Distributed Applications n Could extend use of application to other facilities.
Research Interests n Dissertation touches on: Scientific Visualization n Simulation and Modeling n Physically-Based Rendering n Agent-Based Simulation n
Other Interests n Games and Ray Tracing n n n Machine Vision and UI Development n n Intel is pushing hard to give its extra cores something to do. Real-time ray tracing is the holy grail of rendering. There is interesting research uniting the two. Games and VR n This is underutilized territory. Commercial potential! Shirley, 2006
