END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

MandelnilverV2 dev V2.12 OpenCL.  Alpha 6 of the openCL implementation is available here:

https://github.com/buddhi1980/mandelbulber2/releases/tag/2.12-alpha6

for those who have the time, please try,  as we need as much feedback as we can get in testing with different GPUs.

There is some trialling of various coloring functions  T>HybridColor at the bottom of the transform list. This is currently only running for testing purposes  (not in OpenCL mode.) Various boxFold and SphereFold transforms now have some color control parameters.

Also it allows more coloring options for single fractals and hybrids.

My proof_of_concept  maths is OK, but where and how they will finally be implemented is yet to be determined. Therefore any color parameters in settings files saved using this transform may not work correctly in later versions.

Also abox12 formula is still beta, and will be changed  a bit.

It all seems to be working perfectly well on my system.

Windows 10 64bit with a Nvidia 780 GPU.

Oh, except I got a crash when I tried double precision OpenCL, but I assume this just isn't implemented yet. (I've never actually tried double precision OpenCL on this GPU, but the spec sheet says it can do it).

Please let me know if my assumption is wrong, and I'll give you more info about the crash.

Other than that, all is very lovely. Thank you very much.

I'm trying out the new T>HybridColor function, and while I got it to work, it might be a good idea to have a bit more documentation on how to set it up.  The two things missing (and in retrospect, maybe at least one of them should have been obvious) were;

- It's necessary to ensure 'Use colours from a palette' is ticked in the material properties.  I'd initially tried to just add this as a hybrid into a scene where I'd already set stuff up, including disabling 'Use colours from a palette'

- It's also necessary to select at least one colouring component (they're all unticked by default).  I'd suggest either pointing this out, defaulting to have one of them selected, or optionally both.

That aside, once I got it working, I've seen some interesting results, and it hasn't crashed - which is good.
