Original IFS Fractals
« on: December 09, 2019, 12:32:08 am »
These are fractals that I've designed, so you  haven't seen them before, although some may look like others on the net.
All of them were designed in Apophysis https://sourceforge.net/projects/apophysis/files/latest/download
except for the 'QB64' IFS fractal.

'QB64' was designed using IFS Lab  https://www.nzeldes.com/Fractals/Fractals_core.htm
Both of the software packages are free downloads.

@Johnno56 and Bplus,
I hope these render better than the ones in SDL Basic, they're super fast on QB64!

On my machine all fractals except QB64 render in a millisecond or less!



QB64   (needs a steady hand so it doesn't look like a child drew it. Oh well...)

Hi Andy,

Very nice! amazing what a little bit of code can produce! Not only super fast, they seem super small compared to SDL as I remember, what? 3 years ago??

Say, do you have any pine trees?

Thanks guys!

@bplus

The codes are much shorter because I don't have to :
1) Create a lookup table for alpha-drawing the fractal, just set the alpha level and let QB64 do it's stuff.
2) Don't have to create a histogram array to speed up the rendering process, once again QB64 is plenty fast. Being a compiled language that's not a big surprise.

Long term, I'm going to have to figure out how to work with Inform. Inform seems to be based on VB like code SUBs, where you design the form (UI) which generates the event SUBs, then fill in the SUBs and logic glue code. Very slick! Then I can recreate the fast BlitzPlus Basic IFS Viewer program in QB64.

As for pine trees (Christmas card/demo anyone?), I should be able to find or make a few for you. I'll try to hook you up in the next couple of days (work schedule permitting).

Let me know if you need any assistance with InForm ❤️

Thanks for the encouragement Fellippe!  I may have to take you up on that :)

It's kinda lopsided, but may be able to tweak to achieve symmetry.

Amazing! I have never seen these before. Indeed, they all are original.
How you make this? I mean what you do for making new fractal?

Cool... The only things missing are the scent of pine and the squeaking of squirrels... Nicely done!

@Ashish
The first post has the links to the programs I use for designing the IFS Fractals. When using Apophysis, just remember to turn off the 'flame fractal' settings by unchecking all of the different types of effects (e.g. sinusoidal, spherical, swirl, horse shoe, etc.).

To do this, do the following:
1) Fire up Apophysis
2) Select 'Options' menu from the menu bar at the top
3) Select 'Options P' at the bottom of the drop down menu
4) This brings up an 'Options' dialog box.
5) Select the 'Clear All' button at the bottom right
6) Click the 'linear' checkbox at the top left (make sure linear is the only option left checked).
7) Click the 'OK' button.

Done. Now select one of the IFS fractal previews on the far left.  Press 'F4' and start messing with the triangles.

If you design something you like, save as an .IFS, not as a flame fractal.

@Johnno56
Thanks!  I hope these run a lot better than the others I did in SDL Basic, i.e. no run time errors for Linux users.
