A simple project for learning DX12 and DirectX Raytracing API. Trace 4 rays each pixel each frame(4spp) to capture low frequencies of environment lighting, and use spatial temporal filtering to denoise shading result. Dynamically update the light probe in the scene.
- Use WASD to move camera, and use mouse to look around.
- Use IJKL to move the object in the scene.
- RTX Graphics Card
- Visual Studio 2019 or higher version
To learn DX12 and DirectX Raytracing API, I decide to use the API to write something, then I found implementing real-time raytracing denoising algorithms is an interesting option. As a beginner, it's a great pain to write native non-encapsulation DirectX12 code. At the end, although I made it, the code was already in a mess. By the way, the code structure is built upon Frank D. Luna's book Introduction to 3D Game Programming with Direct3D 12.0 and Microsoft's Direct3D 12 raytracing samples.
You can see the soft shadow and the diffuse reflection of environment lighting.
