New YafaRay v3.3.0 released!

[David Bluecame]

Hello,

I would like to announce the release of the new version v3.3.0.

I want to say something to avoid raising false expectations: there are very few changes between v3.2.0 and v3.3.0. Mostly a feature request for a non-realistic "flat" material (to show architectural cut-outs) and some fixes for Bidir, that's all...

The main reason for this release is to wrap-up the v3.x.x code in a final release before starting with the big changes (and license change to LGPLv3+) that will take place in the upcoming YafaRay v4.0.0.

You can download builds for Linux 32/64bit, Windows 32/64 bits and MacOSX 64bits (however the Mac build needs additional tests, as I only can do *very* limited tests for the Mac builds)

The list of changes between v3.2.0 and v3.3.0 can be seen in the download pages below.

The Blender-Exporter builds can be downloaded from:
https://github.com/YafaRay/Blender-Expo ... tag/v3.3.0

The Standalone builds (to be used with other software than Blender such as Wings3D for example) can be downloaded from:
https://github.com/YafaRay/Core/releases/tag/v3.3.0

what are the panned changes for yafafay 4.0?

Thank you David for your constant work and commitment to the whole community of yafaray ...

[David Bluecame]

Thank you, guys!

About v4.0.0, it's still too early... I can tell that I'm testing some libraries licensed with Apache 2.0 that we were not able to use before, but from v4.0.0 we will use the license LGPLv3+ for YafaRay, which is compatible with those Apache 2.0 libraries.

Implementing these libraries is taking some time. I'm still in the initial stages, but it looks promising... However I don't want to tell yet just in case I cannot make it work

Hi David

I have a question about SPPM that I have found no aswer for by looking at the code, and it is whether SPPM uses russian roulette for early termination of photons bouncing. Regards.

[David Bluecame]

Hello, Álvaro.

Yes, from what I've read in the code, it looks like SPPM uses russian roulette for photons.

[Samo]

Hi David thanks for the answer. One final question about SPPM, I believe given the tests I am doing that SPPM only computes shadow rays in the first pass and that in subsequent passes it only does photons statistics agregation and antialiasing, am I right?

[Harvester]

Thank you David.

Hello, Alvaro.

I'm sorry but I'm not yet sure how the SPPM integrator works. I'm working now in significant changes in the code, starting by the intersections and objects creation code. Once a reach a good new intersections/objects fundamentals, I will continue with a review of integrators and materials.

It's still *very* early, but I'm progressing with my tests... if everything goes well, I think there will be a few nice surprises for v4.0.0!

Why don't you recruit new developers? Just a question.

[Harvester]

And who's going to pay them? Just a question.
