Normal buffer for denoising in Optix 5.1.0

Hi all,

I recently visited the Optix samples page on github, the documentation for optixIntro_10 mentions that the normal buffer is ignored by Optix 5.1.0, is this true? I can’t find any relevant info in the release notes or the programming guide.

Thanks

Yes, that is true.
I asked the engineer who implemented the denoiser before writing that comment.

Hi there, is this true for OptiX 6.0.0 as well?

Thanks :)

Yes, it’s still ignored in OptiX 6.0.0.

Though compared to OptiX 5.1.0 the AI denoiser performance itself has been greatly improved for Volta and esp. for Turing.
