It's a fern and an octopus--a ferntopus? Octofern? It's beautiful, whatever it's called! Amazing Surf (which mclarekin tells me is actually short for "Amazing SURFACE"!) is such an amazing formula to find incredible vistas and scenes with! Parts of it look like bamboo as well (Octo-boo? Octo-bam? Bamtopus?)  cheesy

Thanks a lot. Glad you like it!.
I had some expieriences with a_surf back in 2012 with m3d, so I had a little clou about valid start parameters. Unfortunately I did not manage to reproduce exactly, what I did back then - with or without angle conversion. But don't take this as serious issue, as I also doubt, that I could produce something equal to the one below (or above) in m3d. Every implementation has its pros and cons. Yours at least is very fast. As almost everyting in v2. Even hybrids are no barrier. A big praise for the current version 2.08-x. I'm looking forward to fiddling out, what is possible here...  A Beer Cup

About amazing surf.  I think the difference is that in M3D the rotation happens after the addCpixel vector, whereas Mandelbulber default has the addCpixel being the last translation in the loop.

In theory if Rotation is not used then,   both programs should render the same fractal,

If "Don't add global C constant" is ticked, and you place an addCpixel in slot 2 in hybrid mode, then the rotation should work.  But I have not tested it  smiley

Tanks mclarekin for the hint. When I have the time, I'll give it a try. Difficult to imagine. The second slot should still be the last in line...
At least there once was and I guess still is annother difference discussed and solved here http://www.fractalforums.com/index.php?topic=13130.msg51114#msg51114. I still use the provided tool, to carry rotbox params between the two programms.

opps got that wrong, should be
Slot 1 aSurf , with Do not use globalC ,and rotations set to zero
Slot2 AddCpixel c.x c.y swap (this transform does not work properly in V2.08 so we have to wait for V2.09 to test this out). If it is a Julia then place a addition_constant transform in Slot 2 and enter the Julia constants.
Slot 3 Rotation.


The whole process may be :
you would have to address that original rotation difference between M3D and Mandelbulber
then address the  z axis direction change that happened, between 1.21 and v2.0, by importing 1.21 setting in to V2.08
then address the rotation transform being in a different place, by using hybrid mode.

I have added an addCpixel c.x c.y swap option, before the rotation on the Amazing surf UI. That will remove the last step in the process.

Thanks mclarekin for the detailed explanation. I tried out, with no significant change. In a zoomed out overview, I observed a quite obvious difference. I needed to adjust the min radius a 1000 times smaller in mandelbulber to gain a most equal appearance (0,1 in m3d equals 0,0001 in mandelbulber). Still under investigation...
But again: DON'T CHANGE ANYTHING. The formula is good as is! Maybe you can develop an m3d mod, but please don't replace this!  police
I am sure the relation is NOT linear. I tried this parameter here (at 0,01) and m3d showed up NOTHING at 10. So the divergence must be something more nifty to handle...

Maybe it's good that some of formulas are a little different than in MB3D. In this way it's not boring to see always the same images  cheesy

Not maybe - it is good! This a_surf provides new possibilities, that want to be explored. And btw I currently have a lot of fun, to hunt theese little differences! grin

There are currently lots of amazing _surf variations in Mandelbulber to be tested by users .  In Amazing surf multi we have the choice of five fold types to start with.  If we are adding addCpixel then there is all the possible  c.x c.y c.z swap combinations (and in V2.09 these can  alternate at each iteration.)  Place , say, a Benesi Mag Forward before Amazing Surf Multi in hybrid mode and we have another set of variations.   By adding a bit of z scale to any amazing surf produces some more variation (and can reduce the holes if it is too thin.) ABoxModKaliEiiffie   in dev V2.09 , is set up so it can be yet another type of amazing surf.

The possibilities are so damn infinite that a single user would need a  long time to try them all out. grin  Which is a good thing  grin

Can't wait to see that Amazing Surf GUI box that you're working on, mclarekin! Will that be in 2.09?

Another difference with this particular formula, ( from M3D and other Mandelbulber A surf UI's)  is that Julia.x and Julia.y are also swapped outside of the formula file..  So here it is in  the  dev V2.09 Amazing surf multi UI , which may load in the V2.08 version.

without giving it a try (I'm @ work), I'm pretty sure, it has nothing to do with the fundamental divergence I observed. The min R ratio is still 1/1000.
For the parameter of "machine spirit" I saw annother "anomaly" yesterday. The julia-x value has almost no influence on the form. it adds some wrinkles, thats all. @0 the object is perfectly smooth. x and z component have very different properties in that formula. (Don't take this question personal) Is it possible that x and z are mixed up somewhere in your implementation?

BTW nice sub-structure in your image!
