Yes; this one took around 3 minutes too, David. Used the default custom formula. If you use just z it still would take 3 minutes; of course no change happens afterwards with just z. Still nice to see this ability; maybe can be speed up some. :)

Some of them almost look like continual droste. I like that Conformal maps Lyle.

I'm assuming you need to use the pre release gmic to get that filter?

Yes, Sallyanne, you do need the Gmic 2 but you can install both. They live quite happily together on my machine.

Great turing, Lyle, but very hard on the eyes.

Yup; lol

I got this complaint about this particular pattern before. I guess I'm a sadist. lolol

I'm a bit worried about the timings you get.
Could someone try the filter on Linux. Even on my laptop, it takes like 8 seconds for a 3000x3000 color image, so I can't understand why it should take 3x60 = 180 seconds on another machine, even on Windows ! There must be something wrong that should be fixed.

Gimp 2.8.20 - Kubuntu 16.04 - laptop 8 GB mem 2.8 cpu - settings as shown - original 800x600 to 3000x3000 new image

about 7 to 8 seconds according to my stopwatch.

Thanks James, how many available cores do you have for the computation ?

EDIT : I've always found that gmic on Windows was a bit slower than on Linux, without any explanations why it is like this. Maybe there's only a simple hack to perform to get the same performance as in Linux, I'd be happy to know :)

Wow; maybe I need to install GIMP on my 64-bit Ubuntu VM and give it a whirl. lol

Yes, Lyle, that would help, really :)
If you find that it is way faster, even on a VM, then we can worry a bit much about the Windows version !

Its a 4 core. Supposed to max at 2.8 GHz. ..never seems to get there ;)

I was trying your filter out yesterday in my Gimp 2.9.5 appimage. Some good symmetry effects

edit: this using Gimp 2.9.5 about 2200x2200 pix rendered to same size and it did take about 30 seconds.

Hi Rod,

3 minutes ? That is quite a lot, what was the resolution of your image ?
All the tests I've done have been generated in less than 10 secondes, even for a 3200x2048 image.

Default size output of 1200x1200.

I do have a pretty slow machine though soooo.... no biggy. Happy to just have this filter in G'MIC. Thanks again! :bigthup :)

heckflosse at the PIXLS thread mentioned that it may be how AMDs handle L1 cache that's causing the hiccup. If so, it may leak into VMs. Regardless, I might give it a whirl soon enough. I usually don't tax my VMs and have a minimal type of environment setup for them. Regardless, I'll try to install GIMP and G'MIC on it soon if I can figure out how to install GIMP-GMIC in my VM. lol

I've just got an e-mail from samj, who tried the filter with its own compiled version of the plug-in, and apparently this is going really faster with her own version !
Maybe some bad compilation flags used in my case, I don't know.
That's interesting anyway, maybe this can be fixed quite easily.

OK; took me a bit to figure out Ubuntu. Man; first GIMP launches like near instantaneously. As for G'MIC (after I figured out the hidden directory structure; lol), is like lightening faster. Took around 5 seconds to run (preview fast too). Yup; there's a problem with the Windows build. Not sure what the solution to it will be though. Going to duplicate this note at PIXLS. :)

You just ninja'd me, David. lol :ninja

May look at samj's compile soon. Have to run out for a bit though. :)

So, Lyle, I'm happy to say there are new pre-release binaries/installers available for testing on the G'MIC web site : http://gmic.eu/files/prerelease/ (dated from today).
These new Windows binaries/installers have been compiled with g++, version 6.2.0, so a quite recent one, and apparently this makes a huge difference :slight_smile:
Particularly, the filter Deformations / Conformal maps now takes only a few seconds to run, in my VM Windows.

I'd be really interested by your tests with those new binaries.

Also, I'd like to thank SamJ (Sylvie Alexandre) for providing me with this new compiling environment !

gmic_win.png1069x760 304 KB

And to be sure you are running the very latest version, check out the ENSICAEN logo, it has been changed this morning.
Also @lyle, please note that there are a bunch of new DLLs that come along with the new binaries, so be sure you discard the old ones !

Below's what I just posted at Pixls; just have to say a fantastic build; fast is an understatement. :)

Wow; preview's near instantaneous now (before I had to disable it since it all but would not complete) and I did a 1200px by 1200px with the custom formula and it did so in around 7 seconds. This build's a keeper, David. Going to duplicate this message at GIMPChat. Thank you David and samj.
