Caterpiggle Posted September 8, 2012 Share Posted September 8, 2012 Good morning Everyone, Does anyone know where to find an application(s) that can do the job in real time maker of Fractal ? I am not speaking of "Still frame rate" as photo still but the actually zooming in the eternal state of Fractal. It is ALL Atari 8 bits included 800 (OS B version) if it is possible ? - Atari user.

+JAC! Posted September 8, 2012 Share Posted September 8, 2012 The complexity of doing fractals of reasonable size in realtime (30..60 FPS) has even been to high for PCs until recently. Only with modern GPUs which provide something like "1 processor per pixel" in their pixel shaders this has become possible. So if you think about a 6502 , 1 or 2 pixels would be possible per frame but I think that misses the purpose :-) Everything that existed before was based on precalc, color cycling and pixel zooing.

Caterpiggle Posted September 8, 2012 Author Share Posted September 8, 2012 Because Numen demo has the only 1 frame as photo. So I thought why not to have Fractals applications to make one on Atari 8 bits ? If you have seen this demo, "Numen" required 320K and you will see there ...

+rdemming Posted September 9, 2012 Share Posted September 9, 2012 The game "Recue on Fractalus" uses fractals to render the mountains in realtime. But that is probably not the kind of fractal you meant Mandelbrot and Julia fractal sets are too compute intensive to calculate in realtime on the Atari 8-bit.

snicklin Posted September 9, 2012 Share Posted September 9, 2012 There was a mandelbrot generator in one of the Page 6 magazine entries, though it took a few minutes to complete a picture. Quote Link to comment Share on other sites More sharing options...
Irgendwer Posted September 9, 2012 Share Posted September 9, 2012 (edited) Because Numen demo has the only 1 frame as photo. So I thought why not to have Fractals applications to make one on Atari 8 bits ? If you have seen this demo, "Numen" required 320K and you will see there ... I have some of these generators here. The fastest is 'Fractal Express' where a single frame is a question of minutes not hours. (http://gury.atari8.i...ftware/1482.htm (download link seems to be broken)). Unfortunately the speed is in conjunction with low precision - entering deeper areas results in blocky images. I encountered the first 'real time' mandelbrot generator on a Falcon030 thanks to the use of the DSP together with a small screen area...

mrnukem Posted September 9, 2012 Share Posted September 9, 2012 I have attached a few Fractal programs from my software archive, not sure if they are what your looking for but figured it can't hurt to get them to you.

devwebcl Posted September 9, 2012 Share Posted September 9, 2012 In Antic magazine appeared several articles/programs for fractlas, even an special issue: http://manillismo.blogspot.com/2012/07/fractales-antic.html http://www.atarimagazines.com/v4n12/Fractals.html http://www.atarimagazines.com/v4n12/FractalZoom.html http://www.atarimagazines.com/v6n1/DotHopper.html http://www.atarimagazines.com/v6n10/SierpinskiCurves.html http://www.atarimagazines.com/v8n4/superhop.html http://www.atarimagazines.com/v8n7/UltimateChaos.html http://www.atarimagazines.com/v7n7/LightspeedC.html Quote Link to comment Share on other sites More sharing options...
ivop Posted September 9, 2012 Share Posted September 9, 2012 There's one on side B of Mega Magazine #3, including source code. Please keep in mind that I was a kid when I wrote all that, including the article on side A. Quote Link to comment Share on other sites More sharing options...
Caterpiggle Posted September 10, 2012 Author Share Posted September 10, 2012 Wow ... MANY THANKS for a big tips. I will check out all of those software above and see which software that I like the most. I will let you know which one I like .... Quote Link to comment Share on other sites More sharing options...
+skr Posted September 10, 2012 Share Posted September 10, 2012 (edited) Is this what you are planning to do on little Atari: http://www.fddb.org/?shows=chaos-order-%E2%80%93-a-mathematic-symphony (watch trailer from 3:46 Min on)? Would be cool. But Rocco did that show in 4096x4096 pixels and a highly dedicated render farm computed for months for it. One fine day we will do such thing in our planetarium dome in real time, but this is years away from now I guess.

Caterpiggle Posted September 10, 2012 Author Share Posted September 10, 2012 Interesting movie title above. What I need is formula instructing to the software. Because I can't figure out how to feed the correct or right data to make generator of Fractal's. Quote Link to comment Share on other sites More sharing options...
mike.2000 Posted February 27, 2019 Share Posted February 27, 2019 looking for a Julia/Mandelbrot fractal generator in ACTION! with srccode. Could not find any, checked the links from above already. I'm almost ready to write it by myself. Or better adapting the existing SuperHop.Act Cheerio, Mike Quote Link to comment Share on other sites More sharing options...
Kyle22 Posted February 28, 2019 Share Posted February 28, 2019 Back in the day, my friend Adam Conover wrote a program called Fractasia. I have found this: frac1.arc frac2.arc I hope this helps you. 4 Quote Link to comment Share on other sites More sharing options...
mike.2000 Posted March 1, 2019 Share Posted March 1, 2019 Thanks Kyle22 for your help. I was looking for ACTION! source. Anyway: always interested in fractals and will habe a look at it. Maybe I'll do some ACTION programming next winter :-.)Also: To unArc your 2 files using ARC.TTP : I've seen my ST Gemulator working again since many years. It's still running on Win-10 Mike 1 Quote Link to comment Share on other sites More sharing options...
Kyle22 Posted March 2, 2019 Share Posted March 2, 2019 In SDX, the commands would look like this: C:>FRAC>arc x pcld:frac1 <Un-Arcing happens> And the same for frac2. Why did you need to use an emulated ST to do this? Just wondering? Quote Link to comment Share on other sites More sharing options...
