This project is an engine where you can create/test new shaders in real-time physically based ray tracing system. The main idea is that users can test their own integrators in predefined environment with assets like: meshes, materials, lights and textures. The Vulkan pipeline is abstracted in a shaders form and the only concern for a user is providing either their own scene description or using already existing one.

Check out discord #general for more info or help.

1. Download VulkanSDK and place it in C:/VulkanSDK/x.x.x.x/.
2. Run install.bat script to download all necessary libraries.
3. For shaders compliation you will need python and glslc available form the shell level. glslc can be found for instance in C:/VulkanSDK/x.x.x.x/Bin32/glslc.exe.

Add vulkan path C:/VulkanSDK/x.x.x.x/Bin32 to the Path variable
System variable needed for the project

1. VULKAN_SDK
2. VK_SDK_PATH

C++17 is needed to compile the project.

The scene description and assets are taken from GLSL-PathTracer project [4]. The whole dataset can be downloaded from link.

Download the assets folder and place it in PBRVulkan/Assets/Scenes/. The folder strucutre has to be as follows:

PBRVulkan/Assets/Scenes/
    bedroom/
    coffee_cart/
    HDR/
    bedroom.scene
    coffee_cart.scene
    ...
