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
