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.
Open X360RayTracing.sln in Visual Studio and build it.
You can't build with the 64-bit version of MSBuild so you'll need to run the 32-bit version manually. Open a developer PowerShell in Visual Studio (View > Terminal) and run the following command:
# Create an alias to the 32-bit version of MSBuild named msbuild
Set-Alias msbuild <path_vs2022>\MSBuild\Current\Bin\MSBuild.exeTo build X360RayTracing, deploy it to the console and launch it there, start a build, either through the Visual Studio interface or with the following command:
# Equivalent to msbuild /p:Configuration=Debug
msbuildTo 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
