BSDF Viewer
BSDF viewer is a web-based BSDF parser and viewer written in JavaScript. The project is inspired by Andy McNeil's BSDF viewer.
The goal of the project is to address the current issues with installation and operating system compatibility by developing a web-based viewer for BSDF files that runs in every modern browser.
And if you are wondering what BSDF stands for. It stands for Bidirectional Scattering Distribution Function. If you are dead serious to learn about BSDFs and their use in Radiance then see this slides from the BSDF workshop.
Roadmap
The project is a work in progress and currently does not support TensorTree BSDFs. The parser for TensorTree files has been already implemented but there is no viewer!
Credits
The BSDF viewer is using D3js for interactive visualization.
The legend is modified from this example.
The viewer is using polygon-clipping library for merging outgoing patches for TensorTree BSDFs.
So many thanks to:
- Greg Ward for Radiance, for answering all my stupid questions about BSDF and providing sample code and related documents.
- Andy McNeil for all the above except for not creating Radiance and plus his genBSDF tutorial. And if that was not enough now he has contributed code to the viewer!
- David Geisler-Moroder for the comprehensive BSDF workshop, providing the conversion factors for Klems BSDF and answering my random BSDF questions.
- Rob Guglielmetti for testing and providing feedback and answering my questions.
- Taoning Wang for testing the interface and reporting the bug with Klems parser.
- Eleanor Lee for making BSDFs look easy to understand during her presentations.
- Sarith Subramaniam for helping with the initial push to write the viewer and providing support for using genBSDF.
- [Let me know if you are missing from the list! Thanks.]
