Phoronix: Intel Releases Open-Source OpenPGL To Further Enhance Renderers

Intel used SIGGRAPH today to announce OpenPGL as what they say is the industry's first open-source library for path guiding so renderer developers can integrate "start of the art" path-guiding methods...

For showcasing the potential of OpenPGL, Intel has adapted Blender to make use of it and will be working to upstream it into the software.

Now that's the spirit!
Thanks for that, Intel.

This image is better to show other improvements, the current Cycles implementation can't do the correct lighting in the water

Another info from the Intel article, the images compared in iso render time, 5 minutes, so besides better image quality you have more realistic rendering

What about submitting it as standard to Khronos Group?

Anyway, most Intel projects receive nearly zero community support and their Pull Requests get mostly ignored by Intel developers working on them. Plus obviously ignoring mon-Intel and mostly non-x86 platforms, with a few exceptions targeting Apple M1.

So, this and Embree are never going to be relevant.

I mean there is at least light in the water but it doesn't look realistic. As if someone has overdone the contrast enhancer. Also much more noise.

Edit: In the first picture without water the PGL render has much less noise. So probably better at doing the same and cycles just skips the water therefor less to do and more time for more iterations.

Typo: '"start of the art" path-guiding methods.'

The name sounds too much like OpenGL... I am going to get confused...

That's what I read in the title.

What about submitting it as standard to Khronos Group?

Khronos is mostly about standardizing APIs, whereas this seems to be just a specific implementation. It's not clear how relevant API standardization would be, in this case.

In the screenshots it definitely does look better with OpenPGL but why does both sides look awful?
