As this is a study group...thought of sharing here some tips, Luca
The order of formulae using in MB3D play an important role in shaping the fractal image.
The first formula plays a vital role...for example in a set of formulae " repeat from here" starts from second formula we can say that the 1st formula is a pre-transform...and the remaining formula will repeat in order, according to the no. of iterations..
For eg:-if we take our 2nd teaser... the rot1 can be used as a pre- transform..."repeat from here" is unchecked in first formula...then use bulbox check "repeat from here" then use rot2...it will be like this
rot1, bulbox, rot2 , bulbox, rot2, bulbox, rot2, bulbox, rot2, bulbox, rot2 ... (in short 1st formula is not repeating).
You can use otherwise also...then it will be like this...
rot1, bulbox, rot2, rot1, bulbox, rot2, rot1, bulbox, rot2, rot1, bulbox, rot2, ...
Our main intention of taking a particular formula for teaser is to know more about it... I'm sure bulbox is not a popular one among us...so please make use of this opportunity to know this formula a bit closer...you'll love it for sure
You can try the DIFS also with this formula in DECombinate mode especially in Max mode....try other modes also....(not for this teaser, but for study purpose.)
You have time till 25th Jan to play with this formula!!!
Happy Fractalling!

Wish you all a Happy & Prosperous 2013!
Our 2nd Mandelbulb3D Teaser starts today...
For general rules please see here...[link]
Charles
Here it goes...
You can use 3 Formulae...
Rotate - Bulbox - Rotate
Both Rotate Formulae you can chose from this list as per your choice...
_RotateXYonItsP
_RotateXYonIts
_RotateRnd
_RotatePlaneOnIts
_RotatedFolding
_RotatedAbs
_RotateC
_RotateBack
_Rotate4d
_Rotate
Cutting & Julia are optional...
1. You can submit till Jan 25th.
2. All submissions should be original, i.e., you should start from scratch. No tweaking allowed.
3. If it is necessary, you can use a Background picture, like sky etc... provided, it should not occupy major portion of your deviation.
4. Each participant can submit 2 deviations for a teaser but second submission should be significantly different - i. e. not just another view of the same fractal.
5. Parameter sharing is optional but should give a short description of your workflow. Any tips or tricks used, if you care to share.
Please submit your deviation in the folder "2nd Teaser" and leave a link to this journal also...
Good Luck! Have fun!!!








As for Bulbox, the formula is very slow, as are all those included in the firs tab "escapetime 3D formulas", but some of us have been using for a long time. My very first MB3D was a plain Bulbox work. [link]
Have fun everyone
