Welcome to Fractal Forums

Speedup for the ABoxPlatinum...



Please download DarkBeams newest developements (http://www.fractalforums.com/mandelbulb-3d/re-custom-formulas-and-transforms-release-t9810/) seperately!

Jesse, do you have algorithmic / pseudo code description of the various formulas and combination options? I'd love to implement some of the speedier ones as pixel shaders.

I also added new formulas taken from Bugman site; one is 3D other 4D ^-^

You can open the files with a text editor, many have a description of the formula.
If not, you can ask me for certain formulas.

Now sticky

Benesi3Pow2 really deserves some Julia animations... Anybody inspired?

I found in an old topic two Beth formulas that don't have been included in any release, remember to do it Jesse :)

Merci beaucoup!


Beth has plenty of formulas  look here (http://www-personal.umich.edu/~bethchen/mandalabeth/index.html), or do you mean benesi?
I added some of Beth's formulas, doing them in handoptimized assembler would be very time consuming, so i let them compile... still fast i think.

Bouquet of renders of Quadratic3D formula. I taken it from Bugman's marvellous site. And I opened only a section for now :ugly: ... It's a gold mine of wonders ;D ;D ;D

I know but I'm talking about Beth422 and Beth322, are they included in the 1694? :)

ah, got it wrong... yes they should be included (432+322)


nice, i give it a try - just downloaded the actual final  :)

Thank you very much, not only for these but for the fun I've been having for the past months.  :dink:  :D

Man, I feel like a little kid at Christmas time every time I get new formulas!  Thanks!!!   :cocaine:

Indeed, very inspired !
Just started the rendering of a 6000 frame animation with 2x Anti-Aliasing @ 1600x1200 with this little feller :]
But damn it! Not one image as beautiful as yours ;)
Did you use some transformations?

Good!
But why such a high resolution? Isn't Full HD enough? (1080p)
I did not use any additional formula.

I've got a big screen and was a week away, so I tried to fill the whole week with this rendering. But I've miscalculated a bit, I'm right now at frame 3000 ;)
But next time I'll probably choose a lower resolution ~1080p, there's so much worth rendering :D
You didn't use any additional formula ?! :o I've tried the whole time to get a structure like this but failed ^.^

Just a notifier that i have added a little formula...

_PartlyJulia       - a pretransform to disable partly the julia mode

(More in the sticky first posting in this thread)

Of course, the use of lenords parameters should not say that i think that they need this changings, i liked them just much and so i used them as example.  Had not the right maps anyway...  :beer:

How about a Julia set that fades near the surface of a sphere? Dunno how to make the formula btw :embarrass:

Very interesting Julia option, gotta go play with this, thanks Jesse

If you choose julia paramaters of only zero, i might get a formula, all other values would crash my brain by now   :banginghead:

Maybe if the spheres origin would lie on the julia values... but who cares if no user could handle it  :dink:


Thank you for your work and posting the parameters!

No problem friend, already done a thingmajig :dink: :evil1:

I'm gonna add to the database _PartlyJuliaR ! Get prepared ;D

Did something with keeping offsets, a bit different though...

It is simple to keep the center of the fractal inside the sphere, but we must also modify xyz coords... ;) the simplest way is a "Recenter %". Was thinking to do it... ::)

the  formulas not included in version 1.7.6 are maybe included in 1.7.7 ...or not ?

Of course, the formulas are always updated in the new version.
If you put the new program version in a different folder, make sure to specify the new formula folder with the "ini dir" button in the utilities tab!

Maybe try some of this. At least z=z+factor*z/round(z) transfromation after the Mandelbulb DE formula generate pretty interesting things like cubed mandelbulb;)

 :D wow Jesse just noticed your latest brilliant additions :beer: - I made more combinations but your formula is great ^-^

Thanks, Luca.

I recognized that you also did some formulas based on Aexions ideas (to also rotate C), but had not the time to figure all the stuff out.

Can you do with them Aexions original suggested bulbs? (Sample paras?)

Yes... The param of RamiroBulb is in the original thread :dink: all the stuff works fine

http://www.fractalforums.com/the-3d-mandelbulb/iterating-c/msg39283/#msg39283 see the image attachment params are visible :dink:

But the 'General' formula does not rotate C, so it is something different.  :hmh:

I thought back then, that you were in the wrong thread or so,
...or just flying over it to fast, 250 formula man.   ;D

So many jet? :o

Anyway the param was referred to its basic formula :) rotatec is after it
And the general fmla was pretty easy and fast. Just loading arguments checking for a param value and pass them to atan2 second part is just copypasted... Surely your system was much more expensive...

Have not counted them, i guess this year it will be 250 anyway...  :)

i will include the original version with c rotation in the next version.

Thanks  :angel1:
I think, usefull could be alsou a some mandelbulb variations I uploaded in that file. Just uploaded last one variation with power 8 modulus in triplex. I can imagine, that 80% anywhay would be crap, but 20% alsou could be usefull. (Law of 80/20).

Which file? :hmh: :help:

The same file in the link on page 2. I constantly upload the new versions of Chaos Pro formulas not much caring about compatibility with an older versions :evil1:
I just changed MandelbulbVariations(QUATERNION) adding a "boxed" switch generating somewhat squared mandelbulb (by a modified modulus for the triplex).

I have no time to implement stuff now... :sad1:

OK.

I realy am not shure about the usefullness modified modulus mandelbulb. Just found it few days ago;)

But I was thinking, that unite vector (z=z+factor*z/cabs(z)  or z=z+factor*z/round(z) or z=z*z/cabs(z) ) could be pretty usefull as _modification in M3D. It goes well with mandelbrot, in 2D it could be placed before and after mandelbrot (as in lkm2.upr and tm2.upr). At least there it works with distance estimated mandelbulb. So probably it can go with many other formulas.

At least someday ^-^

EDITED:
Just tested unit vector addition formula placed after the mandelbox. It works, but modification is a bitt weak exept when multiplied with factor 1j. So this could be more like modification for mandelbulb type fractals.

I repeat that it's an experimental feature for DIFS (only - and currently just partially working) it will be included in the nXt MB. Jesse must be very busy lately, he isn't posting ... :sad1:

Witht DIFS I experienced a small problem. These formulas works on public computers, but not on my home PC;) Probably coz of  SSE, as no formulas using SSE work on my age old PC;)

It depends, which model is? ;D

Oldest pentium 3 or maybe a pentium 2;)
