Ray tracing shaders ressources

Unity Engine

Hi everyone,

I’m getting started with writing my own raytracing shaders and I don’t find a lot of resources or doc that can help me.

For the instance I only have this two things :
The unity slides : https://on-demand.gputechconf.com/siggraph/2019/pdf/sig940-getting-started-with-directx-ray-tracing-in-unity.pdf
And the unity doc : Redirecting to latest version of com.unity.render-pipelines.high-definition

But I can’t find any API doc or examples that could help me to write my own shaders.
So please if anyone has some of these it would be a great help for me.
Thank you :slight_smile:

I made a simple path tracer some time ago to learn ray tracing API/shaders in Unity.

It should be relatively easy to understand. It is basically minimal ray tracing application that does something interesting. Feel free to ask if you have some questions.

Friendly warning. I was working on RTAO for a production after this and I encountered a ton of problems. Internal shader compiler errors, things that simply don’t work in Unity (but work in Falcor for example) and a lot of Unity crashes. Rtx in Unity is not production ready. Or at least it wasn’t few months ago.

Ho Good lord thank you very much!
I’m using it for research purpose, so I just need it to be good enough to compare it with rendering techniques and other stuff I made for my PhD.

I’m returning to you if there’s anything I want to ask but this should be enough to me!
And again thank you!
