D3D12 Toy Renderer

This is a personal toy renderer meant as a playground for experimenting with ideas and rendering techniques.

Requirements

• Visual Studio 2022
• Windows SDK 10.0.19041.0
• DXR compatible GPU with Resource Heap Tier 3 support

Building

• Run scripts/Generate_VS2022_Windows.bat to generate VS project files.
• Open D3D12.sln and Compile/Run
