Wow, what a cool julia set    afro
Are you using the correct distance estimator formula? I thought you need one for each formula, based on the grad or some sort of differential of the function.

Glad you like it T wink

Like Luca said, I have no choice in M3D and I am convinced that it has troubles with this fractal.
However, I found some nicer spirals during the weekend and I will do a big render with very low DE-settings of one of these (will take forever to render) and see what it looks like... I will post here when finished.

Well lets hope your handyKRAFT WERKs!

I'm liking these Mandelbrot variations, here's another pic from the dihedral version

Hmmm, the shape of that center spiral... I wonder if the right DE would reveal the spirals of the spiral in the 3D version, sure looks like it has the embryo of that shape in my render...



Nice images btw!!

OK! Finally managed to show the spirals of spirals of spirals of the inside of a 3D julia of this interesting fractal...

Again comparing with Tglads 2D render:





Thank you Tom and Luca!

Somehow this 3D Julia fractal "tglad" type is maybe this Julia set presented by AEXION on his "deviantart" and on
his restricted site WWW.RFRACTALS.NET

Which Julia set? Do you have a link directly to it?

In fragmentarium it works ok using the standard Mandelbulb distance estimator, since the radius is doing the same thing (attached).
This is faster and seems to render better than the no distance estimator version.

Just had a thought, where there is stretch, there is nothing stopping the camera from adjusting its own transform as it approaches and zooms into a stretched area. With a bit of programming this would avoid things getting overly stretched as you zoom.
