How to make...uhm...circular loops?


Recommended Posts

I probably won't be able to put into words I want to do so (not a native speaker) I'll just support it with a GIF first.

This is the gist of what I want to do. I am aware with using radial gradient and 'repeat reflected' I can do something similar to this but new circles do not come out of the initial centre circle I create and the width of the circles also change. Is there a way to do that without plug-ins? And is there a plug-in that can help me do that if it's not feasible without them?

 

Thanks in advance.

Hello @Caesar and welcome :)

 

To be honest, I'm not sure what you are asking.  Do you want to make an animated .gif, like your example?

 

Or do you want a 'static' image that looks like the example?

 

If static, here is  way.

 

1.  Draw a black circle on a new layer.

2. New layer and draw a smaller white circle.

3. Gaussian blur both and flatten.  bHDRtQk.png

 

4.  You can then use The Plugin Droste to get the shape.

First of all, thanks so much for the reply!

 

What I want to do is to make multiple static images that can look like an endless loop when they are turned into a gif. (just like in my example)

 

The plug-in kind of looks like it turns the image into a spiral, which I can already do with gradient. I would prefer if they were all circles instead of a spiral.

The best way would be for you to look at how that .gif was made.  You will need to download @midora's Plugin Animate

 

Then you can view the layers in paint.net to see the 'steps' and how they move.  To do this:

 

1.  Right click on the GIF you've provided and choose Save As

2. Add .agif to the end of the title of the GIF and choose All Files - like this: 

 

Save-As.png

3.  Open paint.net and then import the above saved .agif and all the layers will open for you in paint.net.

4. Toggle the layers to see the movement.

 

It looks like a tricky one to me, so good luck 🤪

You could try this plugin:

 

It is made for manipulating gradient.

 

Though this method would require multiple input/output. I also had did Trigonometry Mapping for gmic. Still require multiple input/output.

 

Your best bet is to use codelab.

See if this is a method you'd like to try.

 

Zoom in on the center square.


That is what the final size of the image would be.


The rest of the canvas is just some needed working space.

 

The expanding ring layers are:
Duplicate layer, selection stretch, repeat.

Here's my rough plan to make these rings happen....

 

1. Make a round selection the size you want.

2. Drag out a radial gadient from black to white centered in the selection.

3. Use @pyrochild's  Curves+ to change the luminosity like this:

 

Gradient-rings.png

The number of peaks and troughs = the number of rings.

The distance between the peaks = the width of the rings. Same with the troughs.

 

4. Use the top option control to save the setting as a preset.

5. Find the preset. It should be in this folder C:\Users\NAME\Documents\paint.net User Files\Effect Presets\Curves+

6. Open the XML file in Notebook.

 

<?xml version="1.0"?>
<CurvesPlusXMLFile xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <CurveMode>L</CurveMode>
  <AdvancedCurveIn>A</AdvancedCurveIn>
  <AdvancedCurveOut>A</AdvancedCurveOut>
  <CurveDrawMode>Spline</CurveDrawMode>
  <ControlPoints>
    <Curve>
      <Point X="0" Y="0" />
      <Point X="22" Y="254" />
      <Point X="36" Y="0" />
      <Point X="47" Y="255" />
      <Point X="70" Y="0" />
      <Point X="84" Y="253" />
      <Point X="100" Y="3" />
      <Point X="116" Y="249" />
      <Point X="139" Y="2" />
      <Point X="149" Y="248" />
      <Point X="166" Y="0" />
      <Point X="186" Y="252" />
      <Point X="202" Y="3" />
      <Point X="214" Y="253" />
      <Point X="233" Y="1" />
      <Point X="255" Y="255" />
    </Curve>
  </ControlPoints>
</CurvesPlusXMLFile>

 

7. Edit the points to smooth out the spacing. X is left (0) to right (255). Y is top (0) to bottom (255).

8. Make a copy of the file, naming it appropriately.

9. Open the copy. Advance the points by increasing the X value of each point. This has the effect of shifting the  Curves+ control curve to the right.

10. Repeat steps 8 & 9 until you have advanced the first control point to the location of the third point in the original file. The number of steps = the number of frames in your animation.

11. Apply each preset to an identical layer (i.e. step 2).

12. Save as an animated GIF.

Anyone ever tell you @Ego Eram Reputo you are a clever chap 👍

 

But for the life of me I can't figure out how to save that setting as a preset 😱

Sometimes - but I never get sick of hearing it :mrgreen:

I was using the regular Curves and only now noticed he used Curves+

 

Yep. Curves+ is required for the saving and application of the presets.
