Abstract

In this project, we have a two-fold goal. First, we plan to produce a working photon-mapping renderer that can handle dynamic light sources. Secondly, we would like to use this renderer to animate light in order to simulate both the illumination from video screens and the illumination from medieval hanging glass oil lamps.

Initial objectives will include research and background reading, meeting with our advisors and group members to plan the overall project, splitting up responsibility for the various portions of the project, obtaining the photometric properties of the glass lamp and material refractive properties, altering a basic photon mapper, and modeling the lamp and the flame. Flame modeling methods will be based on the paper Extending the Photon Mapping Method for Realistic Rendering of Hot Gaseous Fluids by Byungkwon Kang, Insung Ihm, and Chandrajit Bajaj.

After successfully modeling the flame and setting up the photon mapper, the next step would be to generate video texture motion graphs with cached photon emission data based on methods explained in the paper "Video Textures" by Schodl et al. We will use this to create images and/or video clips of our two scenes with glass oil lamps and video screens.
