To build the project, generate solution files in the /build folder with CMake and build it with Visual Studio.

cmake -G "Visual Studio 17 2022" -A x64 -S . -B build

Note: This project only compiles in debug mode for unknown reasons.

• Nvidia RTX cards
  • You will need precompiled copies of dxcompiler.dll and dxil.dll (can be downloaded from here) in the same folder as the project executable. This project uses the DXR for raytracing and the shader libraries are compiled with these compilers. These compilers probably already exist in a Windows 10+ machine but the location or version is unknown. If you wish not to download the compilers or try the DXR features, you can comment out the lines renderer->InitRaytracingPipeline(...) in src/App.cpp.
• Nvidia GTX cards
  • Raytracing is not supported so the pipeline will never be created. You should still be able to run the project without downloading extra shader compilers but only test rasterization-based rendering. This is also untested behavior.
• Any AMD card
  • This territory is unknown as none of us developers used an AMD card during development.

This project uses yaml-files for scene loading where you can manually add, edit, or remove objects in the scene. Scene files lie in the scenes/ directory.

To run the project you also need a configuration file for the project. Duplicate example_config.yaml as config.yaml to configure app settings like resolution and the scene to load.

If you want to try the DXR pong game, set the scene name in config.yaml to pong. Setting it to Pong will load the game scene and not the game itself.

These are some of the limitations of the project that we did not have the time or motivation to fix

• Unable to resize window after initial size (buffers are not resized)
• Cannot add models to the scene through the menu when rendering with DXR (acceleration structures are not rebuilt)
• App freezes for a short while when scrolling the mouse wheel down (bad event handling)
• Cannot have more than 3 lights in scene when using DXR (buffer too small)

• Procedural terrain generation
• Chunked terrain loading
• Texture blending of procedural terrain
• Normal, shininess, and texture maps

• Ambient occlusion¹
• Randomness compute shader for DXR sampling¹
• Transparent and reflective material and objects²³
• TAA compute shader with depth projection³
  • Custom DXR depth buffer
• Motion blur compute shader¹³
• Accurately rendered material using raytracing⁴¹
• Bloom compute shader¹
