Great stuff for the 21st century - impressing!

Dunno if you own a major 3d modeller. Some have pretty good polygon reduction modules. Depending on the model, you can get rid of up to 90% of triangles without a visible loss. Even a complex shape like the mandelbulb might benefit from such a tool (while I didn't try yet).

I used a sphere fold on C to mirror the exterior on the inside.

if(|C| > C_cutoff) {
   C_new = C*(C_cutoff/|C|)^2;
}

Use C_new in place of C in the bulb calculation.

so, people, this is why we use raymarcher instead of marching cubes for visualising

what the guy basically is talking about is that voxel representation is far more efficient than using vector/triangle representation

to understand it, just compare a raymarched mandelbulb with a marching cubes mandelbulb at the same iteration level

the triangles ad an amount of uncertainity to the result, thus, false results lead to wrong connected triangles, this
can not happen when working with raw voxel data, although vector data use more memory
this is what he is talking about in the memory footprint section

awesome, dudes, we just have right now another example of that the art or indefinitely beautiful objects serve a purpose
and he is using just the mandelbulb for analysing such data sets for 3d printing, lols, if he would have hand on a real
3d mandelbrot it would just show more complexity in the differencies between voxel and vector representation due to the
far more detailed surface a true mandelbrot would exhibit

awesome, this is great because i always need examples why i do the calendar, and what art has to do with science,
and the mandelbulb served a purpose in this case, to demonstrate the lack of triangle representation for 3d printers

nice!

the text about voxels vs polygons is just perfect! and should be made sticky somewhere

fractals provide an abstract superficial representation of what should be possible, and funny enough the 3d printers
can provide much higher resolution using voxel data ( because this is what they actually print ) than with vector representation
(because a single dot in 3d would need at least 4 points connected to a pyramid )

and this can be very good demonstrated using fractals because they provide an (sic) perfect (no real 3d mandelbrot yet ) way of what is
basically doable with such a printer!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!eleven!!!1111!thousandonehundretandeleven!!!!1!!!!

Triangles rule!!!

I know in principle, but I thought of the rather plain, whipped cream parts of a bulb. I would think, a good algorithm should spot those and leave the detailed parts untouched.
But obviously bib tried and wasn't convinced - so as long as I don't try, I simply believe him.

I could post images, but I confirm that the whipped cream areas are still full of small triangles even after polygon count reduction using the Quadratic Edge Collapse Detection in Meshlab. Ideally I would like to be able to define what specific areas of the mesh need to be simplified. I still need to test the myriad of options that exist in Meshlab and Fiji, when time permits...

What material has been used? I guess the fine details are very fragile?
