This example manipulates a pwr 5 mandelbulb by inclusion of:

-  boxfold1, used at a pre-mainFormula tweak,  late started at iteration 1 to reduce it's influence,

-  fab() functions,   note: fabsFormulaABCD1_old_weight 0.21,  to reduce influence of this parameter group.

- mixture of additionConstant2 (note julia parameters are additionConstants, z = z + constant) and constantMultiplier2, z = z + ( c * constant). (A lot of my exploring with Mandelbulber  V1.21 OpenCL custom formulas, has been done using these constants placed both before and after the mainFormula)

For V2.05 extended formulas it was decided to try and make the maths semi-self explanatory, therefore many of the parameter groups are labelled with  formulas rather than names, but not all. In the example above we have a  parameter called Old_Weight. It was a simple proportion function that kind of works  but was replaced with a more correct function. However Old Weight is still a worthwhile tweak in some cases, and can generally operate in the range of 0 to 1.3.

//OLD WEIGHT

temp = z;
Transform bla bla bla producing a new z
z = temp + ((new z - temp)  * Weight;

This example demonstrates how a mandelbulb surface can be altered with the addition of  a small influence of boxfold. The attached code has no boxfold, if you render then enable boxfold1, render then also enable boxfold2 and render,  you will see the different surfaces.  Note there is a small increase in render time caused by the inclusion of boxfold with this Mandelbulb, if this was a Mandelbox the difference would be greater. You need to balance the number of parameter groups against acceptable render time.

When you end up with a lot of parameter groups enabled, it is often good to test which ones can be disabled with out affecting the fractal image too much. Some initial tweaks may turn out to have little or no affect after some subsequent tweaks have been applied. If you can reduce the number of parameter groups that are enabled, you generally decrease render time and increase image quality.

Yet another Mandelbulb Extended example.  (The mandelbulb fractal is relatively fast to render.)


This example has a boxFold1 starting at iteration 1, which probably produces the nine spikes. Spike tips are clipped off by a bailout of 10 (worked with this image but not always.)

 At 800x600, Quality Detail level  is down at 0.6 and Step multiplier is really low at 0.03, and still the bad quality had to be hidden by a bit of volumetric fog.
The bad quality is probably due mainly to the first fabs() formula used, having a "weight" of 0.5. Generally when using the "weight" function, the worst settings have been found around 0.5 (half way.)

Note that the first three fabs() formulas on the Mandelbulb _ extended tab, have "enable fabs" checkBoxes, whereas the other three  fabs() formulas have "enable" checkBoxes, the difference is important.

After setting up this image (by tweaking another), I checked and found that there were two parameter groups I could disable, and still the render time was longer than I like.

This example is for a simple hybrid Quaternion- Mandelbulb.
Rendering the attached .fract file will produce a quarternion sphere, hybridised with a mandelbulb sphere  =  sphere

Now enable the addition of a constantMultiplier ( z = z + ( c * const.) below the enabled quarternion mainFormula (Formula#1 tab), then render.
Now also enable the addition of a constantMultiplier ( z = z + ( c * const.) below the enabled mandelbulb  mainFormula (Formula#2 tab), then render.  Now you should have the attached image.

Then tweak away, its like working with clay on a potters wheel.

This example uses Quaternion "w" parameters, for these parameters to work an initial "w" value other than zero is required.  In this example we add 0.9 to z.w in the first iteration, from then onwards, other "w" parameters can be tweaked.

The attached .fract file is a boolean union of two quaternions. Note that as boolean operators is enabled, the Transform functions have appeared at the bottom of each Formula tab, allowing  scale/rotate/shift  for each fractal, (but not used in this example.)

 Disable boolean operators on the Hybrid tab and render again to view the single version.

Quaternions - more
I have found that with quaternions, a  detail level up at 4 if often good to give more surface texture.

I am still learning the potential of  Mandelbulber V2.05, but I prefer to  using  Quaternion- extended as a hybrid with Mandebulb - extended. As quaternions can be a bit boring.

With the above example ,fract file,  go to fractal - primitives, and enable circle#1. Quaternions often look less boring if they are coming out of a surface, and you can get the lighting shadow effect, (thanks JoeFraq.)

This quaternion - extended fractal, demonstrates keeping it simple, it is fast enough to allow Multiple Rays AO. It is simple and plain enough that the DE fits well.

This fractal iteration loop uses only four parameter groups:-
  the basic quaternion sphere,
  a single addition constant to z.w
  a rotation of beta angle
  a box fold for only one iteration

Try rendering the various  combinations of having three  of the four parameter group boxes enabled, and you can see the influence they each have.

Highlight (Ctl A) the contents of  the .fract text file and copy, (to clipboard.)

Now in Mandelbulber V2.05, use File – Load setting from clipboard... 

Note that the  camera/target coordinates all = 0, except camera y  = -20, viewing straight down the y_axis,  (this makes the maths and orientation easier.)

I want to intersect my two clone fractals (currently invisible) at the left and right hand side of my original fractal.

So using the on-screen pointer coordinates tells me  x = 6.2 looks close, but to be sure I go to Primitives and create  a temporary 0.1 rad, 12 height cylinder and locate it at x = 6.2, render. Hmmm, looks close enough for this example.

On Hybrid tab, enable boolean operators.

Formula #2 tab, scroll down to bottom and Transform, shift x = 6.2, y = -6.2, Z-axis rotation 90. Render.

The go to Formula #3 tab, scroll down to bottom and Transform, shift x = -6.2, y = -6.2, Z-axis rotation 90. Render. Hold on! Formula #3 is NONE , because it was not enabled in the original file. OK  Choose “mandelbulb -  extended” from Formula #3's  drop down menu then apply the transforms.  All the correct parameters will be there.

Formula #4.  Enable the formula by choosing “quaternion – extended” from Formula #4's  drop down menu then apply  transforms Y-axis rotation -90, and shift y = -15. Render.

In this example we have built a boolean union image of a group of four existing fractal parameters  simply by "cut and paste."

Note. Colouring options with these boolean operator  group fractals is currently limited.

This “Mandelbox – extended” formula example demonstrates  the “brush stroke” effect from having the rotation transform placed after the addition of constants. It is just a standard -1.5 scale rotbox, with the rotation moved down the loop and late starting at iteration 1.  Tweaking the start/stop at iteration parameters can have a major effect on the resulting fractal.

This example demonstrates  the iteration weight transform, located at the bottom of Mandelbox – extended and Quaternion – extended formula tabs.

      z = (z  * Const.Z ) + (zA * Const.A )  + (zB * Const.B )

At the end of each iteration of the loop functions we have the current “z”,  a vector containing 3D coordinates (z.x, z.y, z.w) for a point in 3D space.

In this example we start with a standard -1.5 mandelbox, but at the end of iteration 2 we assign the current “z”  to  “zA”, from then onwards this new zA (acting as a constant) is added to the new current “z” at that end of each subsequent iteration. We can multiply zA by a constant,  scaling it's influence on the iterations that follow.

There are also zB parameters on the tab and more could be added, the possibilities are  infinite, but the quality  likely to deteriorate.

Standard mandelbulb with a 50% transform "weight" of a box fold operation only on iteration 1.
Try changing the weight to 0 and to 1 and you will see how you can animate the introduction of  this transform.

The use of "weight" in animation has to be tested beforehand as some setups work and some don't. (You can also use fog to disguise slightly bad quality)

This Quaternion – extende example  uses the ability to set  the stop/start iteration parameters to transform the image, which can reduce render time.

This simple quaternion based fractal is made up of  three transforms :

Box Fold stopping at iteration 4, (with weight reduced to 30%)
Basic Quaternion element – the sphere
and z =z + (c * constant), starting at iteration 2 and stopping at iteration 4

Try adjusting BoxFold_stop   from 4 stepping down to 0, then move the third transforms stop up to 5 then down to 3.   A single step can make a lot of difference to the image.

Also note that when the  if( start < i< stop )  conditions are not met, then the internal transform function does not run, saving render time.   In some cases  a parameter only needs to run  for a few iterations before reaching a state,  from where  all further iterations of that transform are just extra render time and do not visibly change the image.

Copy the code,

Then go into mandelbulber and go to File and choose  Load settings from clipboard is the easies way

 or,

download the .fract file  (parameter file) and save it some where , then in mandelbulber go File choose load settings and navigate to where you stored the file
