Discussion Overview

The discussion revolves around the mathematical and artistic implications of the Mandelbulb, a three-dimensional fractal structure. Participants explore its properties, potential analogues to the 2D Mandelbrot set, and the mathematical formulas that describe it, as well as its aesthetic appeal and origins.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants express awe at the Mandelbulb and its mathematical underpinnings, suggesting that the math enhances its artistic value.
  • Questions are raised about the formula for the Mandelbulb, its internal structure, and its relation to the 2D Mandelbrot set.
  • There is curiosity about the variations of the formula and the behavior of the Mandelbulb at infinite iterations, with some aspects remaining unknown.
  • Participants inquire about the fractal detail at lower versus higher powers and whether this detail continues infinitely upon zooming in.
  • There is mention of a Julia equivalent to the Mandelbulb and questions regarding its volume and Hausdorff dimension, which are also unknown.
  • Discussion includes the historical context of the Mandelbulb's naming and its development by various contributors in the field.
  • Some participants speculate on the potential for coloring the Mandelbulb and the software needed to render it effectively.
  • A comment suggests a philosophical connection between the 2D Mandelbrot set and the 3D Mandelbulb, likening them to a "thumbprint of God."
  • One participant makes a tangential remark about extraterrestrial life in relation to the discussion.

Areas of Agreement / Disagreement

The discussion contains multiple competing views and questions, with no consensus reached on several of the technical aspects and implications of the Mandelbulb.

Contextual Notes

Some mathematical properties and definitions remain unresolved, particularly regarding the behavior of the Mandelbulb at infinite iterations and its dimensional characteristics.

This is AWESOME! & 1000x awesomer if you know about the math behind it. How could a painter or sculptor come up with something like this? Math is much better:

see more pics here, but it's not very interesting because there's no explanation:

& more theory & many more pics here:

Oh wow...that's very, very cool!
 
there are some good questions on the 2nd page also:

Further exploration of the creature
There are so many questions we can ask about the structure and nature of the object (we'll stick mostly to the power 8 version for now):
•What's the formula of this thing? (see the page)
•What does it look like on the inside? (see the page)
•Any interesting analogues to the 2D Mandelbrot set? (yes)
•Is this thing really new? (as far as the author knows it is)
•What variations of the formula are possible?
•What happens at infinity iterations? (unknown)
•Is the object completely connected, and maybe path, locally, or simply connected? (also unknown)
•Why do lower powers exhibit less fractal-like detail than higher powers? (unknown)
•Does fractal detail really go on forever when you zoom in? (probably)
•Any Julia equivalent for it? (yes)
•What is its volume and Hausdorff dimension? (unknown)
•Are there near exact copies of the object deep inside the structure? (as of right now, no)
•Any way to colour the object, to replace its mono-ish appearance?
•Any decent 3D software to render the beast?
•If the 2D Mandelbrot is the thumbprint of God, what does that make the 3D Mandelbulb?
 
They first called it a "Broccoli Virus".

A fellow going by the name of Twinbee (Daniel White) was posting here on PF in August, asking about various https://www.physicsforums.com/showthread.php?t=331883&highlight=Twinbee". Look about halfway down the page for the first appearance of this object. Together, these guys are amazing, and have been in dogged persuit of a 3D Mandelbrot-like object since September 2007!

Daniel White's website is hosted http://www.skytopia.com/project/fractal/mandelbulb.html" .

David Makin hosts his own site, so frequent visits could cause him some dispair unless you want to purchase his art.
