An Open Database for Physically Based Rendering

Information

Abstract

The propagation of light and its interaction with matter can be simulated using mathematical models, most commonly Bidirectional Reflectance Distribution Functions (BRDFs). However, the creation of physically accurate BRDFs and their verification can be challenging. In order to be able to test and verify physically-based rendering algorithms, various methods have been researched. However, they are rarely used by the community. One key to the verification of rendering algorithms is to provide test-methods and test-data. Another key is to motivate the community to actually use them and run more tests. This thesis focuses on the latter. For this purpose, the author designed a web-application called “Open Database for Physically-based Rendering (ODPR)”, where test-scenes of different types and from different studies will be merged into one publicly available place. A prototype for ODPR was implemented. The web-application uses community-driven design-patterns similar to StackExchange-sites, and allows scientists to register and upload test-scenes. The idea is, that ODPR will be built up and maintained with the help of the community, by providing free downloads of test-scenes and additional privileges to registered users.
