Welcome to Fractal Forums

This one was rendered relatively quickly because there are no hard shadows. The result is not bad though.

Sit back and watch in HD!

Whow !  :dink:

Another master piece! It made me happy. Thanks.  :)

Thanks for the nice comments (on Youtube as well ;))

I find these 3D fractals so amazing to explore I could do videos non-stop if I had more time :)

Beautiful as always ! I really like the way you use fog in this one.

Always a pleasure to see your animations bib!

"relatively quickly", may I ask how long time that was?
What FOV do you have in this one? >80, I guess... ;)
I also wonder what goes on in the mist the last minute...  O0

Thank you KRAFTWERK.

I think it took about between 1 and 2 days to render, on a core i7. I'm not exactly sure because I did pause it sometimes, and I also tested the Intern parameters while rendering (number of threads, thread priority). With the maximum performance parameters and no pause, it would probably have rendered overnight.

Yes with the rectilinear lens and a FOV around 80-90, that gives a more dramatic perspective.

OK, so you've gone i7... sounds great! Overnight!
A pure windows PC i guess, I run a i5 mac with Windows via Parallels at the moment, works pretty nice, but might be time to buy some new hardware next xmas or something...  O0

Almost spot on on the FoV :)

very nice!

So for a zoom-out like this, what is the range of iterations? I see dynamic level of detail being done by varying iteration count (and/or minimum dist? or just distance?).
I guess more a question for implementers; just wondering what approach is taken for dynamically adjusting detail w/o introducing jumpiness. And then how to color consistently, w/o banding etc.

@marius

Iterations : 1 to 60. There are no variations in iteration count, so no reason to introduce jumpiness, and no variation in any other DE parameter. The varying level of detail at the beginning is due to the fact that I reached the zoom capacity of the program on several occasion when the camera passes by the surface of the object.

The consistent coloring is achieved mainly because I used an almost 100% homogeneous blue palette. In general I think that to avoid color banding, it's good practice to use the widest range possible between Col start and Col end, and to set Col var on Z at 0, but no guarantee ;)

What's happening at #t=122s and onward? Lots of level of detail related morphing, no? Or did you start varying some box parameters at that point? Notice the corners of the box as you zoom out as well.

(append the #t=122s at the end of the youtube url. Can't seem to link to that here like that w/o triggering an embed that drops the #t fragment?)

Yes these are just parameters variations. I progressively reset rotations to 0.

This 3D fractal footage has been used by some friends musicians "Supa Hataz" at the famous French music festival "Printemps de Bourges" last April. Here is the video from the concert:
