Ray tracing experiment on the Xbox 360.
This project is an Xbox 360 port of TheCherno's RayTracing renderer built entirely on YouTube in a fantastic series. The Cherno implemented a CPU-side ray tracer but this project utilizes the GPU as much as possible to do the heavy calculations.
There is currently a bug when running the code on real hardware. The image is split in half and forms 2 triangles, the bottom right triangle renders properly but the upper left one doesn't.
It looks like a strange behavior of the IDirect3DDevice9::Resolve implementation on Xbox 360 because the bug doesn't occur in Xenia. It seems to happen when sampling from a texture that was written to using IDirect3DDevice9::Resolve.
If anyone has any explanation or a potential fix, feel free to open an issue and/or a pull request!
- Having the Xbox 360 Software Development Kit (XDK) installed.
- Xbox 360 Neighborhood set up with your RGH/Jtag/Devkit registered as the default console (only necessary if you wan't to deploy to your console automatically).
Open X360RayTracing.sln in Visual Studio.
Xbox 360 projects can't be built with the 64-bit version of MSBuild, you need to run the 32-bit version. You can make yourself an alias for convenience:
# Create an alias to the 32-bit version of MSBuild named msbuild
# The default installation path of VS2026 is C:\Program Files\Microsoft Visual Studio\18\Community
Set-Alias msbuild "<path_vs2026>\MSBuild\Current\Bin\MSBuild.exe"To debug X360RayTracing, you need to build and run the debugger from Visual Studio 2010.
To build X360RayTracing in release mode, deploy it to the console and launch it there, start a release build, either through the Visual Studio interface or with the following command:
msbuild /p:Configuration=ReleaseTo build X360RayTracing and run it in Xenia, start a build with the Xenia configuration, either through the Visual Studio interface or with the following command (Xenia will be downloaded automatically the first time you run the command):
msbuild /p:Configuration=Xenia
