Hi there,
I've just registered in this forum and this is my first topic. I hope I do everything well. If not, please report me. (I'm learning fast  grin )

I'm a 3D artist since the 90s and when I saw the 3D mandelbulb for the first time (several month ago) I'm looking for a satisfying solution to get this freeky geometry somehow combined with the content of other 3D programs. So here is my latest try:

In mandelbulb3d I've exported voxel slices, combined them to a geometry again in ImageJ, reduced the polycount in meshlab, cleand and optimized the geo in 3dsmax and maya and textured and rendered it in vue. A making of of that process is in the 2nd part of the video.

My conclusion after this study is, that this was not the best way because:
- In the first frame (from far away) I have a resolution of 1 polygon per pixel. But when I get closer the fractal effect gets lost, because the resolution is baked in the geometry - which is not very fractal like.
- So I tried to get the resolution back by using the fractal textures from vue (eon software). These are great for natural fractals like stone cliffs but not of the same formula like the geometry from mandelbulb. So the overall effect of this nice geometry gets somehow lost.
- And getting a clean usable mesh out of the voxel slices was hard work (original geo was 16 mil. polygons), I prefer to let the cpu do boring jobs for me and concentrate myself on the creative part.

So next thing I will try is to render the geo directly in mandelbulb3d an track the piece via 3d motion tracker to get the camera information out of it and reuse this in another 3D program. Suspense continues!

If this was the wrong section to post this, please let me know.

Have fun with the clip...

hello and welcome to the forums, amazing project you work on there, if you havent seen the news#5 of chaosTV the contest this year submission period
starts at 1st of may, i am going shortly announcing the contest rules, be sure to hold something back to be entered in the contest because previously released stuff may be disqualified ( if we get known  of it ... )

additionally, take a look at mandelbulber, this one can export 3d information and various image channels for a 3d render, this can then be used to stitch in polygonal geometry in a post work step....

Thanks for the tip. I already have mandelbulber installed, but didn't took a closer look to the export options - yet. Maybe I'll give it a try.

Unseen productions for the contest ... good to know. I've only seen the Chaos-news till #4   Azn

1st of may - yep that's good incentive
