One Shot Radiance: Convolutional Auto-encoders Deeper in Ray Tracing
Welcome to the pbrt-v3-OSR wiki.
One Shot Radiance is an experimental rendering engine based on PBRTv3 that uses a neural network to predict indirect illumination, with full Global Illumination support, support for a wide range of materials, and no need for precomputation.
One Shot Radiance is capable of high performance Global Illumination with a very low noise level, and is a useful biased ray tracer for use cases that don't require physically correct output, but need noise-free indirect illumination that looks convincing in most cases.
I have written a paper about the project, and I will add a link to it once its review process is completed and it is approved (hopefully!).
Quickstart
There are different ways to obtain PBRTv3-OSR:
1 - Blender plugin with PBRTv3-OSR included
A blender installable package with all PBRT binaries included.
Tested on Ubuntu linux 64bit
InstallBlenderPluginWithPbrtIncluded
2 - PBRTv3-OSR only
3 - PBRTv3 Blender Exporter Plugin only
Blender exporter only. Compatible with vanilla PBRT.
4 - From source
Info
Exporter: blendPBRTv3
Info about the One Shot Radiance modification of PBRTv3 will be published once the paper is approved (expected for October 2018).
