This is an official implementation of the paper "Real-time Indirect Illumination of Heterogeneous Emissive Volumes using Layered Polygonal Area Lights". For more details, please visit our project page!
Use CMake to build the program. Our program depends also on https://www.glfw.org/ and https://glm.g-truc.net/0.9.9/index.html. Please install these libraries to your computer beforehand.
For Windows, you can build it ordinarily using CMake GUI and Visual Studio.
For Linux, you can build and run the program by the following commands.
>> # Build
>> git clone https://github.com/Paul8029/IndirectIlluminationLPAL.git
>> cd IndirectIlluminationLPAL
>> mkdir build && cd build
>> cmake -DGLFW3_DIR=$PATH_TO_GLFW3 -DGLM_DIR=$PATH_TO_GLM -DCMAKE_BUILD_TYPE=Release ..
>> make -j4
>> # Now, you can find "main" executable in "build/bin".
>> cd bin
>> ./main ../../data/config.txt # Please specify your own config if necessaryWe tested the program using Visual Studio 2019 and GNU GCC v8.3.0 (g++) with C++17 filesystem, so please make sure your compiler supports filesystem when using another complier. Also, our program uses compute shader of GLSL and tested using OpenGL v4.5.
When running the program, please specify config.txt to the executable. If you wish to test your own volume data, please modify volumeFolder section in it.
We included a simple static volume in data/density.vol and data/emission.vol. Also, you can download our animated data from Google Drive.
