Hi!

I understand, maybe incorrectly, that a fractal image is (1) a set of numbers, generated by a formula, and displayed as POINTS, and (2) rules for coloring the POINTS.

In UF, is there a way for replacing the POINTS with SHAPES (e.g., a triangle)?

If so, how do I do it?

Thank you!

Dr. T

I think "points" refers to how the value of each pixel is determined and coloured (by the formula and colouring respectively). If that is correct then I think the answer to your question is no.

If by "shapes" you mean a set of similar shapes that iterate in a fractally generated manner (i.e. different size copies as generated by the formula being used) then you probably need one of the many "orbit trap" style of colourings. Look up "Orbit Traps" in the Help file for more info.

Here is a very simple example of an "Astroid" (star-like/cross) trap shape made with a Julia formula and Orbit Traps (UF3) colouring. The iterations (copies) vary in size and are arranged in a regular and orderly fashion as dictated by the Julia formula. The stars themselves are created by the colouring:

Many different trap shapes are possible. Most of these orbit trap style of formulas offer a choice of set shapes that you can further distort/manipulate through various functions and parameter settings. More advanced techniques can involve devising more unusual multi-trap shapes through the use of plugins.

I'm not sure if this answers your question.

Params for the above so you can look at the construction... look at the Trap Shape colouring parameters to see how the "shapes" can be changed:

Dear Chris,

Thank you for your reply.

Yes, when displayed as an image, a point is a pixel that has a value generated by the formula. The coloring rules (a combo of the Coloring Algorithm and the Gradient in UF) assign a color to each value.

You did answer my question. I am trying to do something very similar to your Astroid example. Use a Fractal Formula such as the Julia Set and a Coloring Algorithm such as the Orbit Traps that you suggested. I’ll look at Orbit Traps.

However, my ultimate goal is to use a shape such as a Golden Spiral (a common geometric shape), which may or may not be available in the Orbit Traps. And, as of now, plugins are “beyond my pay grade.”

I wonder if is possible to create a layer with the image of the shape (e.g., a Golden Spiral) and then, somehow, use the image as input to the Coloring Algorithm.

Ah, well this is where plugins show their versatility! Using plugins it is possible to devise a spiral trap shape (though not necessarily a golden spiral) which could be deployed in the same way as the astroid shapes above.

Your other idea, of using an image and mapping that onto a fractal in an iterated way is also possible using an "Image trap plugin". This, however, can be a wee bit tricky so again I would say it is a rather more advanced procedure but it IS possible.

Here is an example of an outside image, a clock face, applied to an orbit trap arrangement in one of my images: LINK

I regularly use various textures from imported images to texture trap shapes in my work too. So there are a lot of creative possibilities with these techniques.

Ron Barnett has a series of very thorough tutorials on the use of plugins here:
http://www.hiddendimension.com/Challenges/UF5Challenges.html

They are intense but informative and will give you all the information you need to make a start with this method of creating fractals. You need to start at the beginning and work your way through the list in order. Number 9 covers image import.

Given time to properly study and practice this material you should be able to figure this out. It took me several months to get a real handle on all this but it is intensely rewarding when you start to understand it.

One more time, thank you for your reply.

I'll work through the tutorials.

By the way, in the first tutorial, I saw a UPR script. How do I paste it to UL?

Just select & copy the whole block of text from the starting title: Fractal1 all the way down to and including the final curly brace at the end: }

Then open a new fractal window in UF or click on an already open one and paste. UF should then present you with the image.

Similarly if ever you want to share your params:

  • click on your fractal image window
  • Ctrl-C to Copy
  • go to your forum post/email/reply window/Facebook or whatever and Ctl-V to Paste the text there.
  • On this forum there is a toolbar command for pasting a code block (the page icon with <> on it). That's what I use for pasting parameters here.
