This repository holds the source code to the new version of pbrt that will be described in the forthcoming third edition of Physically Based Rendering: From Theory to Implementation, by Matt Pharr, Wenzel Jakob, and Greg Humphreys. As before, the code is available under the BSD license.
Please see the User's Guide for more information about how to check out and build the system as well as various additional information about working with pbrt.
Over 4GB of example scenes are available for download. (Many are new and weren't available with previous versions of pbrt.) We're trying an experiment and making them available via git. Run:
$ git clone git://git.pbrt.org/pbrt-v3-scenes
to get them. We will update this repository as more scenes become
available. (See the README.md.html file in the scene distribution for
more information about the scenes and preview images.)
The pbrt website has general information about both Physically Based Rendering as well as pbrt-v2, the previous version of the system.
