Diopter

Vulkan 1.3 real-time path tracer using rpp and rvk.

You can download a standalone Windows executable here.

Scenes

Diopter supports most PBRT and GLTF scenes. You can find scenes here:

• pbrt-v4-scenes
• Benedikt Bitterli Rendering Resources
• glTF-Sample-Assets

Support

Diopter requires a GPU with hardware ray tracing support. The following GPUs have been tested:

• RTX 3080ti
• RTX 4050

Diopter has only been tested on Windows, but also builds and theoretically works on linux.

Build from Source

Download the source:

git clone --recursive https://github.com/TheNumbat/Diopter

Windows

Install the latest Vulkan SDK, Visual Studio Build Tools, and CMake.

mkdir build && cd build
cmake ..
cmake --build . --config Release

Linux

Install the following dependencies:

• cmake 3.22+
• clang++ 17+
• pkg-config
• libgtk-3-dev
• libsdl2-dev

To build the shaders, you'll need to download DXC separately.
