GPU-accelerated real-time path tracer powered by Vulkan and C++.
Stingray is a real-time path tracer leveraging the Vulkan ray tracing pipeline. Delivering high-fidelity graphics with a minimalistic and efficient design philosophy in mind.- Fully bindless resources: Buffers, images, and acceleration structures are efficiently managed without the constraints of fixed bindings, enabling maximum flexibility in rendering pipelines.
- Fully path traced: Includes physically accurate shadows, reflections, refraction, and global illumination.
- Lean and mean: Very minimal and clean abstraction layer over both Vulkan and the rendering hardware interface (RHI). Stingray makes very little use of OOP design patterns, opting instead for a data-driven approach with POD types.
- Automatic GPU synchronization: Stingray utilizes a render graph to manage resource barriers between passes, ensuring efficient execution.
- Vulkan SDK version 1.3 or higher.
- CMake version 3.6 or higher.
- Windows 10 or higher.
- Microsoft Visual Studio.
- GPU with hardware ray tracing support.
In order for all dependencies to be downloaded with the project, you must recursively clone this repo via:
git clone --recursive https://github.com/JackiBackiBoy/stingray-rt
Once downloaded, run the build.bat script which will automatically create a build directory. Or alternatively run:
mkdir build
cd build
cmake -S ../ -B .
cd ..
You will also need to compile the Vulkan shaders, which are not automatically compiled. Run the compile_vk_shaders.bat script.
You can now open the .sln project file located in the build directory with Microsoft Visual Studio. Also remember to set
stingray as the "Startup Project" in Visual Studio. This can be done by right-clicking the
stingray project and select the option "Set as Startup Project".
You should now be able to run the program!
