Dearest,
I am a complete newbie and I wonder ; how come a 3d obj file created with Mandelbulb 3d and Fiji look like sprayed with a foam after imported into Meshlab (SEE ATTACHEMENT), how can this be? I mean, in Mandelbulb 3d the fractal has f.e. straight clean corners/boxes after rendering in Mandelbulb, in FIJI it looks tight as well but after loading in Meshlab the .obj file has a bubble foam appearance. Can these be flattened? When I try this with Sculptris Sculptris gives me an error message during importing the fractal .obj file ; ' too many triangles connected to an edge (max 2) . Can I modify the .obj in Meshlab so Sculptris does import the obj file? Cos then I could try to ' flatten' the surfaces of the .obj. Or is it that any values in Mandelbulb 3d need to changed to get almost the exact result as the 3d fractal looks like in ~Mandelbulb 3d?
Many thanks in advance for answering
kind regards

Hello and welcome to the forums  The obj export is a feature that is ahead of it's time technologically! To get the details sharper you need bigger voxel stacks, and that means prohibitively huge obj files (dozens of gigabytes!). Getting it fine tuned is an art that is dependent on your hardware and software. People get best results with monster machines using huge amounts of RAM and able to handle files of several GB with no difficulty. The best results I have seen came from ZBrush, which is a pricey program, but in this case you really do get what you pay for! The best approach is to use low poly obj files with high resolution bump and displacement maps, but that feature has yet to be implemented anywhere I have seen. Meshlab's decimation tools help reduce file size, but reduce details in the process. Give it a decade or two and we'll be able to handle these files a lot better! Until then, just find the settings that work best within your system's limits and don't do extreme close up renders. Hope that helps! Here's one of the better results I got using obj files in Carrara:  |

Why not to use the internal mesh-generator? Is more sophisticated than the use of voxelstacks, is much faster and has preview

Please help me here, the internal mesh generator in Mandelbulb 3d? OK, I'll check it out , thanks. kr |

That is called "Bulb Tracer" and I think it is under the "Tools" tab, but I am at work and can't confirm at the moment... It's a nice feature, but I never worked too much with it as it was a recent addition and haven't made an obj file for a while. |

I am using a Mac and this feature I cannot find on the Mandelbulb 3d I use ( 1.9) As far as I believe the ' new' Mandelbulb 3d is 1.9.9 and is not available ? |

It's highlighted in the attached image. I think the mac wrapper guy never did do the later versions, but am unsure, however; MB3D runs fine under WINE. Or at least it did when I had a mac... Hope that helps. |

meshlab is great , i keep the source on my box for remeshing point clouds but the viewer is right out of the 1990's and motif even on my 5+ year old i5 with 8 gig ram and a older legacy support nvidia card Blender ( and meshlab) can work on a 2 gig mesh -- a bit slowly , but usable . you might want to see what the obj looks like in blender a comparison using StructurSynth blender then meshlab     |

STructurSynth? What? Where? How? I guess you can understand what I mean |

Where and how can I download 1.9.1 working for Mac then?
You can't download a "version for mac" since it doesn't exist, but you can get WINE (a windows emulator, despite their claims tht it isn't!) (either way, it is a framework for running windows software natively on a mac without installing windows!). I don't have a link (posting from work again) but WINE is a common item for mac users and should be easy to find. Install that, then you can run not just MB3D, but many, many, other windows programs too! A worthwhile tool to have. |

more or less this site is stealing the download file from our site, it is in no way an official download, the official download is solely from our site: http://www.fractalforums.com/index.php?action=downloads;cat=51.9.1 can be found here: http://www.fractalforums.com/index.php?action=downloads;sa=view;down=64the file you download from our site is garanteed to not be modified, usually those sites stel files from others and contain them in some format they want, it is just crap they put outside the file (in some cases ) the original is the direct download found here on this site |
