Easier to convert to .obj

[cyseal]

I tried to make and 3d object in Blender but I failed with voxel data technique.
Is it possible to make .obj without using other older software?
Could you implement some technique to make it easier using only Meshlab or Blender?
Thanks

Hi cyseal.

Have you tried FIJI?  Blender is a great program, but notoriously difficult to use.

You can also convert MB3D's Voxel Stacks to obj files using JWildfire's Mesh Generation feature.  They both take some getting used to, and practice, but results are worth it!

This bulb was created in FIJI from MB3D's voxels and rendered in Cararra:

What exactly was your problem? What step was too complicated?

@Sockratease , @thargor6 Fiji has stopped working in the middle of the process. I tried it again over a day with small sample and nothing.
Is it possible to update algorithm Fiji uses and implement it in MB3D?
So, I'm looking a way to overstep the use of Fiji.

FIJI often gives the illusion it has stopped working, but is in reality still doing things in the background.

Often you have to just wait a while for it to finish writing the file.  Have you gone back and checked again on any files that may have given the appearance of failing?  

Have a read through the Voxel Image Stack And Then What? thread for other people confirming this  (sorry, a lot of the images I posted in there are lost from an old problem on the site I was hosting them).  There are several options in there for the process.  The thread is here : http://www.fractalforums.com/tutorials/voxel-image-stack-and-then-what/

Be aware that these will be HUGE files - often over 1 GB each  (which is where MeshLab comes in for decimation) - so the extra lag time and appearance of freezing up are understandable.

Good luck with it!

You should use for this step JWildfire instead, the results are almost the same, but it is much faster (because of multithreading) and gives more feedback, and you get a simple preview of the generated object

As thargor6 said JWildfire works way better than fiji for working with voxel stacks ...... I have done a tutorial on how to do this located here-- youtu.be/HP_zCyuMEao

Thank you thargor,Snicker02  and Sockratease !

When importing voxel data and generating mesh in JW, is 4GB ram enough?

[JohnVV]

there is a blender plugin
https://github.com/NMEMine/BlenderFractals

it is 2 years old and it dose run on the current blender 2.76
do to the calculations and mesh HUGE size this script takes a LONG time to run -- single threaded

Blender is a great program, but notoriously difficult to use.

no harder than 3D Max or using Renderman

it just takes time to learn
just like  The Gimp or Photoshop

In the past I have used Clemency to create 3D meshes.

I need to start it within cmd?
How to set a path to voxel data?

Is it possible to implement whole MB3D as Blender plugin or renderer within Cycles or Internal ?

How to set a path to voxel data?

As far as I understood the post (had no time to test the program yet) it not generates a mesh from a stack of voxels, but by evaluating an opencl-fragment which you have to create/adopt. Because it has this way some kind of the "formula", it may be much more clever than the standard MC algorithm which just works on a fixed grid size.
At least the Mandelbulb as shape is supplied as example (mandelbulb.cl), you may start having a look at this.
