It's a plain Quaternion Julia, power 2, with only the first two parameters non-zero, so it is approximately possible in XD, Incendia and others. However, Chaoscope does the Julia differently, with depth limiting, which you have set to 8, which is why it's smooth and rounded. Incendia and XD don't do that so they could only give a more detailed object. It should be possible to get that by using one of the raymarching programs with depth limiting, and voxel stacks for export.

Thanks!  I knew there was something different about the way Chaoscope was rendering Julias because I could never reproduce that  (or even get a good approximation in other software.  I actually never heard it called "Depth Limiting" before and that may have been causing me to miss some options - I'll have to re-check and try again.

And I only mentioned Incendia because of my budget  sad  It's free version makes better obj files than the free version of Xenodream  (which I still can't fit into the overly tight budget around here).  But if you can approximate that in Xenodream, feel free to post the xep file and I'll be sure to post something made from it using those fancy 3D programs I love so much   afro

The Level control sets the iteration level for depth first ray casting, according to the manual.
In Chaoscope, just set the Level control to 15 (press Enter after editing numbers) to see roughly what it would look like in XD. There seems to be a bug with level 16 or higher, as it changes scale. Also, the sign of Ci seems to be reversed. It doesn't look nearly as good for exporting as the smoother version.

This post takes me down memory lane and it was cool to revisit my forgotten chaoscope images ( Chaoscope being my first fractal experience).
Now for my first experiment of using "Attach".
