How To Run A GMIC Filter On Hundreds Or Thousands Of Layers

[teapot]

I like your background Tas_mania.

Nice one racer-x, all the details come together to make an impressive result.

Just a simple one, I've been playing but not making much:

A really nice outcome teapot

I've been fascinated by infinite zooms for awhile. Racer-x made one that was deceptively simple (for me anyway).
I tried to use a G'MIC batch script to make one.

Here is the script I made.
#!/bin/bash
mkdir ./done
for i in 01.png
do
gmic $i -fx_zoom 0.0125,50,50,0 -o ./done/$i
done
for i in 02.png
do
gmic $i -fx_zoom 0.025,50,50,0 -o ./done/$i
done
for i in 03.png
do
gmic $i -fx_zoom 0.05,50,50,0 -o ./done/$i
done
for i in 04.png
do
gmic $i -fx_zoom 0.1,50,50,0 -o ./done/$i
done
for i in 05.png
do
gmic $i -fx_zoom 0.2,50,50,0 -o ./done/$i
done
for i in 06.png
do
gmic $i -fx_zoom 0.3,50,50,0 -o ./done/$i
done
for i in 07.png
do
gmic $i -fx_zoom 0.4,50,50,0 -o ./done/$i
done
for i in 08.png
do
gmic $i -fx_zoom 0.5,50,50,0 -o ./done/$i
done
for i in 09.png
do
gmic $i -fx_zoom 0.6,50,50,0 -o ./done/$i
done
for i in 10.png
do
gmic $i -fx_zoom 0.7,50,50,0 -o ./done/$i
done
for i in 11.png
do
gmic $i -fx_zoom 0.8,50,50,0 -o ./done/$i
done
for i in 12.png
do
gmic $i -fx_zoom 0.9,50,50,0 -o ./done/$i
done
for i in 13.png
do
gmic $i -fx_zoom 1.0,50,50,0 -o ./done/$i
done

Note. There is a trick in this zoom. It's really an optical illusion IMHO. This is what I put in the export all layers box to suit the script.

I exported 13 frames, ran the script, opened the frames in Gimp and reduced them to 6. This is a good way to waste time and/or get zoomed.

Excellent idea with the magnified beetle, teapot. It came out great...

Those zooms can become hypnotic, I guess your still in a trans, Tas?

[Tas_mania]

Wow teapot you turned a roundabout into a mini planet. That's impressive.

I notice with 'Inverse' Transform selected on Stereographic Projection you can make a landscape. The moveable dots are great also.

[racer-x]

Yeah, very cool teapot. The beetle looks like it's on a turntable.

Anyway, I tuned the motor in my Mustang and it now does wheelies...

Looking good racer-x


I think there's a slight design flaw in this one:

[Tas_mania]

Hi racer, I can get spoked wheels turning in 720 video but not really working in a GIF. Those wheels are lookin good

teapot. I like your faulty design. Did you use Array [Mirrored] or another filter?

[teapot]

Hi Tas_mania, I used fx_symmetrizoscope.

[racer-x]

Really crazy effect teapot, but I like it. Thanks for the comments guys.

I like the "Sketch" effect and I also desaturated this one. The older you get, the harder it is to get it up.

You can still get the hood up on a Mustang

I stole some ideas from teapot.
My gifs were scaled-down video clips but the wheels no longer worked so I re-did them.
I like how you can apply multiple G'MIC filters to an animation. I did the background with a bunch of filters, the last one was 'Faded Mirror'.

[Tas_mania]

I discovered Reptorian Vibrato and added Water. Background has Rotate by Torus Map.

[racer-x]

Great special effects Tas_mania. It's amazing what adding filters can achieve. G'mic can be used for a lot more than just still images.

[Tas_mania]

Thanks to the contributors on this tutorial. I'm going to send it to the Gimp Chat archives by diesel locomotive.

[teapot]

Wow, impressive results racer-x and Tas_mania

The large rotating ball is cool. Is Rotate by Torus Map new? I don't think I've got it.

Nice train Tas.

Old Game counsel type animation.

Hi racer I just watched the Hoonicorn 4WD Mustang with twin turbos.

I've been investigating how to make the backgrounds of my GIFs a bit smoother.

I'm using long 'pano' images (with matching ends) from Wikimedia and distilling them down to less than 100 frames. This method may work for looped video but could be improved for GIFs.

This time I used a background image no longer than 4 times the height of the GIF. By using a filter like G'MIC Conformal Maps, pixels in the background have to move in both the x and y fields not just from right to left.

[racer-x]

Yeah I watched a few Hoonicorn videos in the past, it's a ridiculously fast car.

Where is the "G'MIC Conformal Maps" location?

[Tas_mania]

Hi racer-x. Conformal Maps is in Deformations. It looks confronting at first and the batch script has to be escaped with commas (thanxs teapot). This is the command I used in the last animation

Code:

gmic $i -fx_conformal_maps "4,1,0,((1.1+i*z/6)/(1.04-i*z/6))^6.2,0,-163.08,-0.044,-0.1,0.04,3,3,0,1024,1024" -o ./done/$i

Another interesting one is Cartesian Transform in Deformations. It also has to be escaped. This one makes the background move in 2 different directions.

Code:

gmic $i -fx_custom_deformation "w*0.4,(w/h)*sin(x*2)/h,1,1,3" -o ./done/$i

Hoonicorn and K.Block. I found his vehicles here.
The Hoonicorn has a 6.7 litre (410 cubic inch) engine. Not so good for the environment but in the big picture it's better than doing drugs.
