Fractal Tree

[lainz]

Hi, this is my first fractal tree I ever made, I'm very happy 

Source:
https://github.com/bgrabitmap/demo/blob/master/fractal_tree/umain.pas

Thanks to @circlular for BGRABitmap as always, and also thanks to Rosetta Code for the actual algorythm (that I tweaked just a bit).

Edit: Oh, I think I removed the actual fractal thing adding randomness  (added advise in code: Use even values without randomness to get a 'real' fractal image)

Really beautiful

Made a Symmetric Fractal Tree from Lainz code on GitHub.

but on my netbook with a smaller screen the picture is out of whack. When I make the canvas wider I almost see the whole tree.

This is what it looks like on my bigger laptop (correct view) and the OutAWhack Netbook one

I think the problem is scaling the canvas for different dpi/resolutions.

Very good

Actually I was playing around with branch thicknesses between levels. Below are some samples along with source code (I deleted the icons from each folder to save on space).

I thought of making each branch sort of radial filled gradient lines to make them appear as though they were round. I also need to learn how to add spin/textboxes to vary the different values as well as use a listbox to save and load preset values and how to save to a png file. The more I play around with your initial source code the more excited I get.

My initial stumbling block was how to add BGRABitmap to Lazarus, but after doing some Googling I finally worked that out. I downloaded the source from https://github.com/bgrabitmap/demo and have been tinkering with it over a couple of days.

Bgrabitmap is very addictive

Just a Fractal Blob that I made. Enjoy.

Cool. I had not thought of that. Tree in all directions makes blob.

Hello.

Here the Fractal Tree dancing (needs to enable sound):

and here the superformula in transe:

Nice to see the Fractal animations posted by Fred vS.

Would be nice to control the speed of the animations.

Also thought of making my Fractal Blob rotate slowly from right to left, to simulate the movement of a Tumble Weed (Like on those old American Cowboy desert scenes). I like Fractals.

Thanks!

In the animation (not really fluent from screen-capture, as the "true" animation from the program), the speed and shape are defined by the spectrum and volume of the sound.
You may try it from the project StrumPract, in menu choose "Image Dancer".
https://github.com/fredvs/strumpract/releases
There are also other BGRABitmap animations like Turltle by Lainz and Atom and Spiral by Winni, the code is in imagedancer.pas.

Very cool!

By coincidence, I have been writing a fractal program for fun. I was fascinated in the 1980's and just started a new project, because I am procrastinating from actual work.

[VTwin]

One more.

[VTwin]

Another... (the last I promise)

Merry Christmas to All Lazarus Forumn members.

I have uploaded the tree fractals code and exe's to my Github page (just in case someone wanted to play with them) at: https://github.com/BoleeMan/Lazarus-TreeFractals

I have also been playing around with PascalABC.Net (Free pascal program). It has a more watered down interface but can do some really cool stuff. I uploaded examples also on another Github page at https://github.com/BoleeMan/PascalABCProgz

Hopefully it will give people some ideas to do some similar things in Lazarus.

Here are some examples below:
