An offline ray tracing-based renderer for fun

Aurora, is a learning-oriented rendering system in the style of PBRT. Hence, this project were mostly ported from pbrt-v3 with much customization and adjustment out of personal habits. I plan to develop this project as a long-term project in my personal spare time. Learning by doing!

This project is built with following third parties.

• GLM for fast algebra and math calculation
• stb_image for image I/O
• glog for logging and debuging
• nlohmann_json for parsing json file of the scene

I build this project on Windows platform. Please make sure your system is equipped with the following softwares.

• cmake：at least version 3.5

• Microsoft visual studio 2017 or 2019

Please compile the project for x64 platform.

1. Clone the repo

   git clone --recurse-submodules https://github.com/ZeusYang/Aurora.git

2. Use cmake to build the project：

   mkdir build
   cd build
   cmake ..
   make
   

   or using cmake-gui is ok.

Please make sure that clone the reposity with --recurse-submodules option. If you foget to run git clone with it, just type the command git submodule update --init --recursive.

After successful compilation, run Aurora.exe --help in the command line could get the follwoing prompt:

usage: Aurora [<options>] <filename.json...>
Rendering options:
  --help               Print this help text.

Logging options:
  --logdir <dir>       Specify directory that log files should be written to.
                       Default: system temp directory (e.g. $TMPDIR or /tmp).

  --logtostderr        Print all logging messages to stderr.

  --minloglevel <num>  Log messages at or above this level (0 -> INFO,
                       1 -> WARNING, 2 -> ERROR, 3-> FATAL). Default: 0.

  --v <verbosity>      Set VLOG verbosity.

For example, in order to set the scenes/cornellBox.json as an input scene file, you should type the command as shown below:

Aurora.exe ./scenes/cornellBox.json

More features and scenes are planned.
