I launched the calculation of the animation in 1600*1000 with 1400 frames at 28 fps based on the above sequence with one or two added keyframes to smooth transitions (without antialiasing and motion blur). Should be ready on Monday ;-)

Thanks David, it seems higher bailouts make it a little worse. On average there are less sooty streaks if it is reduced from 10240 to 1024, but the colours change to lower in the spectrum, more greys and greens. I'm not sure why the bailout needs to be more than about 50... it is the square of the distance right... so on a 2d mandelbrot you could use 4? and about the same for the mandelbulb. How could a point out at radius 30 be inside the set?
The larger the bailout the more accurate the distance estimates are (all methods) this is because generally speaking they rely on the bailout iteration approximating the infinite attractor rather than it simply indicating "not inside". Another reason that could explain the spotiness is the values you're using for the "Minimum step distance", "Minimum search distance" and "Delta distance" (or if you still have "Automatically calculate distances" enabled). Typically for the Mandelbox try disabling "Automatically calculate distances", setting "Minimum step distance" to 100* smaller than the solid threshold, "Minimum search distance" 10* smaller still and "Delta distance" 10* smaller still (or even smaller to an absolute minimum of between 1e-14 and 1e-16).

Thanks David. I tried out variations of these values but nothing made much difference, but then I tried changing a few other values and found that change in the 'DE adjustment' from 1 to 10 fixed the problem. No idea how it works but the soot is gone! Bib, this could fix sooty problems in your vid too. The pattern at the end of the sequence looks quite 2d, but with some fog and a close up you can see it isn't a dead end. You can climb through the hole and drop down, where you'll come out back into the cradle again.

In that case a better solution is to change "DE adjustment" back to 1 and increase the value of the solid threshold by up to a factor of 10. A non-zero "DE adjustment" modifies the actual solid thresholds used based on the distance from the viewpoint of the "solid" on a point by point basis and the correct value to use is 1.0 -- using a value of 10 means that further from the viewpoint points are registered as "solid" at much higher distance estimates.

just wondering: How would the 2D-equivalent look in this case? (eg cut through the central plane where z=0) They all are very nice

Someday, man will understand primary theory; how every aspect of our universe has come about. Then we will describe all of physics, build a complete understanding of genetic engineering, catalog all planets, and find intelligent life. And then we'll just puzzle over fractals for eternity.

Awesome ! This seems to be a single frame from "Monsters Inc." ?

Yep, the door warehouse is what I was thinking of
