Hi,

I was asked to share some nodes for a Julia-Set ...

I simplified it for 2 iterations ... once you get the point, feel free to add more ... to your needs and the power of your machine ,-)


Have fun,

Volker Harun

Wow, thanks Volker!

For those who don't know what a Julia set is: http://en.wikipedia.org/wiki/Julia_set

The possibilities are endless! The node implementation is very clean as well. Awesome!

Hi Volker
Huge thanks for this :)
There's a huge stack of learning in here.

This is way over my head and i can't see this for creating canyon networks but it would make good for artificial or alien terrain structures.

Thank you Volker!!

And compliments to matrix2003 on your new avatar!!  I like it lots - which I wouldn't have been able to say before.   ;D

Fractals for me were old DOS programs. But at that moment in time,  I thought this was so much cooler than anything I had done on my TRS 80  or commodore 64 !
Fractint, Ultra Fractal, Fractal Explorer, and there was another one I can't remember.

Oh.  Believe me you can say anything in here.

Thanks, So just duplicate this to get 100 iterations.

My idea for this: pack 1 iterations inside a 'Buildvector' node using "dandelO's device"
pack 10 nodes of this inside another 'Buildvector node' still using "dandelO's" device
Finally pack 10 of these in a final 'Buildvector node'
Of cource you have to use the beta version.
dandelO's device: connecting assigning an input tab of a node to the output of an internal node.

You might want to try the following:
Delete that multiply and dot-nodes at the bottom. Instead you use first a build vector (feeding only x and z) followed by a length to scalar.

This is more typical.

First image, 9 iterations took 2h30m with detail set to 1 and aa at 11
Yep this is gona get slow :)

Cool,thanks!
Now go for some mandelbrot. ;)

Volker Harun

Cyphyr, this going very good!

I was too lazy yet, to get rid off those outer boundaries ... should be possible with a conditional scalar.

@J meyer: Just replace the scalar 'Real' with 'X to Scalar' and the 'Imag' with 'Y to scalar' on every iteration ;)
