Very cool, now do it with analogue synthesis.

Bold statement for a 7th post.
PhineasFreak.....did you make this?
HOW?
I like it a lot. 

Robba 
Wow!
(Had to laugh fo the first comment though!)

This is a pretty clip!
While you couldn't do this kind of 3D modelling completely with an analog computer, I'm really excited about the potential of hybrid environments, such as high speed, videorate voltage control over elements of a fractal generator or 3D engine, and texturemapping of analoguesynthesized elements. Fractals are something I still have a lot to learn about. 

numan7 
Tthat was some of the nicest fractal artwork i've seen!
Plz get out of the loonybin quickly! And make more of these!!
cheers,

Thats some nice software! Should be working on school, but its very tempting to play with the fractals. Haven't figured out yet how to render a movie... 

numan7 
fractal geometry was one of my favorite university subjects  much of our homework assignments used the old Logo programming language, where you would command the graphicsturtle to move different colored pens around the screen to generate various fractal images.
Btw, the above image sort of reminds me more of a figure called the Serpinski Gasket:
...than it does the Mandelbrot Set:
Maybe the SW is mixing the two together, kind of like wallpapering the Mandelbrot Set with the Serpinski Gasket...
Anyways, it looks does look unbelievably awesome!

You may notice how the SG can be generated with a simple transformation diagram above, where applying the same transformation law is applied to each segment of the figure generates the next approximation of the fractal.
In the case of SG, this transformation can be thought of as removing the central inverted equilateral triangle enclosed by the equilateral triangle segment > resulting in 3 smaller equilateral triangles, one stacked on top of the other 2.... which then have their middles removed and so on...
A simpler family of fractals, known as Dragon Curves, are made by bending segments of lines:
The Mandelbrot Set is more difficult to visualize that way  it is easier to demonstrate its construction in terms of compact, closed sets of integers ("eisenstein integers", to be exact) in the complexplane.

Very interesting. You should be able to generate something like the Serpinski Gasket using logic, dividers and VCOs in the analogue video synthesis world. I've seen those types of figures created with these techniques in the EMS Spectron, see the B&W images further down on the page here:

Awesome !!! I've always wanted to get back into fractals, and what more exciting way to do it than video synthesis!!
Btw, here are a couple of simpler dragon curves than the one given above:

after looking at the tetra and pentadragon curves for a while, i made some simplifications, so that the mappings became proper functions (ie, waveforms) by more or less clipping off the "embedded stuff":
These pseudodragons will still become fractally on top, as the order of approximation increases, but stay log/linear/exponential along the sides.... I wonder how hard that would be to synthesize?
cheers,
n7 

lizlarsen 
Hmmm, interesting. It seems possible, especially if you rotate those patterns 90 degrees and think of the fractal itself as being a repeating waveshape in audio range.
Mathematically I suppose it's a matter of translating whatever geometric equation there is to equate to a raster display, which deals with preset frequencies. Use of a vectortoraster converter module (or vector rescanning) may open up some new geometric possibilities here too.

Yah  and the 5dragon in particular looks like it can almost be synthesized using nothing but fm'd pulsewave and offsets.
Late last night, I tried to fm'img 3 VWGs together I had set up as test patch for something else I was doing, and attempted to approximate the 3rd approximation of the pentadragon using:
VWG 1 pulse out into VWG 2 fm1 in,
VWG 2 pulse out into VWG 3 fm1 ,
VWG 3 pulse out into VBM/CVE/Projector<====
Aand I thought I was seeing patterns that were vaguely dragoncurvelike. I'll post a video doodle of it later...
cheers,

lizlarsen 
Awesome. This kind of discussion is very exciting.
For the fivedragon, a sequencer clocked into audio rates, with the clock source reset by Field (V) Sync, and the output FM'ing a Line (H) Sync'ed VWG could be interesting! 

numan7 
The audiorateclocked sequencer idea worked out really, really well, i'd say!
I also patched in a MATHS clocked as a logarithmicshaped LFO, to sweep the primary VWGs frequency. It really does look like it's trying to become a fractal! Now I think I'm going to need some more VWGs at some point (for higherorder approximations )...
I *will post a video* (actually 3 videos  1 here and 2 in the videodoodles thread) oh... sometime in the next several hours.
You see... 'Searching For Dragons  Pt 1' came out at around 9 mins / 1.8 GBytes... Aand although it appeared to upload and transcode successfully, the youtube said I had deleted the file  and *poof* the dragons vanished... <oh thanks so much, youtube (and/or me  whichever was more at fault in this instance)> ... but they're on their way again!

maybe i'll put up a videostill in the meantime.

you can get some great analog fractals using video feedback (camera pointing at screen the output is projected onto). If you rotate the camera, instant fractals!

cool thanks for the info (I seem to recall that one of those was based on the other, from my geometry studies dating back to twentysome odd years ago)!
aand here's a dragon (well, a pseudodragon... sort of... ):

Yup. And add a little interference in the image to cause the detail to stick out.
Here are some stills from the MVIP feedback recording I posted here a couple of months ago:

Cool  I'll try giving this technique a shot tonight....

First off, I should stress that I merely posted this after someone emailed me a link  it's not my creation!
Am glad this sparked some discussion  I was a little sad when noone showed interest at first.
And the concept of creating fractal based outputs from analogue synthesis is something I was scared to think about, having imagined it would take row after row of modules to create!
Now I can't wait to rejoin the real world and build me my new video synth.

That's cool Phineas!
I think my "dragon" videos showed that you can more or less get in the fractal ballpark with 3 fm'd video oscillators and a mixer  the first of vidz, over in the doodlesstickythead where I'm twisting the frequency range knobs, manually shows it the best. I'm very intrigued by the thought of what could result from adding 1 or 2 more VWGs to the modulation chain (whilst "rotating" the picture using fieldsync and audiorate sequencing, like the 2nd and 3rd videos experimented with).
I still need to set up for the MVIP patch Dave suggested above (maybe tonight if I can tear myself away from my digisequencer idea for a couple of hours ).
Anyways, get well soon!
cheers,

This has got me thinking of some other exciting possibilities  I would love to investigate the use of fractals, attractors and stuff like fibbonacci's serquence to be the sequencing source or modulation source for perhaps just colour mapping or other relatively basic parameters of video sources in a patch...
Annoyingly having yet to get my hands on modular video synth gear my imagination is slightly limited due to having no clue about likely results from even some basic patches.
There's an incredible temptation to start ordering my system now whilst I'm stuck in here, especially since I'm not spending money on much compared to normal, but common sense dictataes I should wait until I've had the psychiatrist's initial assessment later today and hence at least know a ball park figure of when I might get out...
