Thanks blb! I just got lost checking out "source Forge" Only interested in free-ware. (have other priorities) Just getting decent a zoomin. Not all programs all equal on that.

Personally I would put Mandelbulber at the top of the list...
I have to agree. The new key frame option is just awesome. I have just finished putting a sequence of keys together. It was a little tricky to get the hang of at first - but I worked it out soon enough. I cant wait for it to be finished already!

I definitely have to spend some time learning Mandelbulber, but my first impression was that I did not understand the logic of it, particularly the GUI. Anyway, I'm now in my Mandelbuld 3D phase and having much fun with it, so I would warmly recommend it because it's quite easy to learn. The only thing I'm not comfortable with in M3D are the shadows. I can't get nice "projected" shadows like I used to do in UF with Dave Makin formula, and it seems also easy to do in Mandelbulber.
Is it possible in Mandelbulber to do hybrid fractals (that is changing the formula at each iteration) ?
Edit : by the way, who has been using the 2 programs and what would be the pros and cons in your opinion ? MarkJayBee ?

Have you tried the hard shadow option? It is calculated only for the first light and you have to adjust the angles for light and shadow by hand to fit. But it gives better shadows and you dont need to turn the ambient shadow so high. The sliders for the hard shadow in the lighting tab have to be adjusted more to the right side, just try it out.

Yes I have tried that. What I can't do for example is to draw a distinct shadow of a peak on a plane surface, like if the shadow strengh depends only on the surface normal, and not on objects around projecting their own shadows. So I'm not sure I exactly understand how hard shadows work, but the fact that they're updated in real time by the sliders makes me think it's too quick to be what I'm looking for. Maybe I need to test more, I will try and post some screenshots if necessary.

Yes, GUI in my program is not so perfect . When I finish some new features I will try to make Mandelbulber more intuitive. Generally I hate building user interfaces Is it possible in Mandelbulber to do hybrid fractals (that is changing the formula at each iteration) ?
Not yet, but I will be in near future. Now there is only possible to mix all formulas with IFS and Mandelbox formulas (base and auxiliary formula in the same iteration).

Just a quick hint because this thread is not only related to M3D: You have to turn the hard shadow option in its tab on before rendering, only the amount and gradient can then be changed after rendering. Of course, it takes some more time to render because an additional ray must be calculated.

BTW I was having a lot of problems with ChaosPro, bugs & such. I thought that doing the updates would take care of it. But no.. anyway I just downloaded it again. Love it, have more features & better than ever.

Hello:
I'm new to the forum. I'm a graduate student in architecture @ Miami University and am looking at 3D fractal geometry as a generative methodology for building structure + form for my thesis project. I'm searching for the best/easiest 3D fractal generating software to use ... and one that exports into some sort of 3D MODEL format ... not just making cool/pretty/interesting 2D IMAGES.
I looked at "FractalWorks" but it seems to only be able to generate 3D images from a limited amount of original/existing fractals (perhaps I'm missing something)?
Does anybody have any suggestions recommendations?
Thanks!

Hello and Welcome to the forums! You may enjoy this thread: http://www.fractalforums.com/mandelbulb-renderings/mandelbox-architecture/As for a decent Mandelbox obj file (or other 3D format) Export, I have no idea. Maybe Visions of Chaos ( http://softology.com.au/voc.htm ) But I am still hoping to get a sample of the output to judge it's quality. Or perhaps one of Terry Gintz's programs? http://www.mysticfractal.com/ Xenodream exports fine obj files too : http://xenodream.com/If you find one you like, let us know! EDIT - These obj files will always be HUGE because they are generated from "point clouds" and not actual surface geometry, thus they have a ton more polygons than needed and often contain internal polygons hidden from view but part of the formula so they get rendered!

Thanks for the welcome and the direction everyone. It's a little overwhelming stepping into this realm (initially) of finding a good match of software and (my) skills ... or lack thereof! The formulas and mathematics are a little mind-numbing. I'm hoping to find a software that is intuitive and less reliant on "numbers".

I suggest starting with Mandelbulb 3D from the Downloads section here (link up top). Very easy interface to get used to. Just change some numbers in different places for different formulas at random to get a feel for what happens. It doesn't do obj format (that is a rare request - I thought I was the only one who REALLY wanted it!) but maybe if enough of us keep asking, Jesse will add that to the program

I tried to use Mandelbulb 3D to create a 3D object and I think I failed only because I couldn't find a free software, even a command line line one, to make an stl file out of a stack of B&W 2D slices animation walkthrough I rendered with it. Does anyone know about such a tool? I wish I could create an stl out of those bitmaps, then there are enough free tools to convert that to an obj which I then could render in Kerkythea. Ideally, if Jesse would implement stl export some day, that would be uber cool.
