Ray Tracing In Dot Net is a real-time path tracing demo that performs hardware ray tracing via Vulkan's ray tracing extension. It is a port of Ray Tracing In Vulkan to .NET and C# using Silk.Net, with some added features.
- Dynamic scenes (allow update transformations to models, rebuilding TLAS.)
- Added "Cascading Mirrors" demo scene.
- Added "Physics" demo scene using Bepuphysics v2.
- Toggles for full screen mode and vsync.
-
A GPU with ray tracing acceleration cores (NVIDIA RTX 2000 series / AMD RX 6000 series or better GPU. Older GPUs may work if the vender has enabled fallback shader-based ray tracing, albeit much more slowly.)
-
Up-to-date display drivers for your GPU.
You will need the Vulkan SDK from the official site.
- Needs a good denoiser (or any denoiser, for that matter.) This is especially apparent in scenes that are never stable, thus can't accumulate rays (the Physics scene.)
- Optimize BLAS meshes by sharing identical ones across TLAS instances.
- Add more materials / make them more flexible.
- Allow a user to load external model files.
- Modifying a shader file alone will not cause a recompile by Visual Studio; currently a rebuild must be manually forced.
