Thanks blob. This is pretty much what I did using the above instructions. What's next? Where do I load the image stack?

When I click on Start Map, it says "Module ObjSaver1 has no connection on any if its output ports. You must connect at least one of its EvokeUpdate ports in order to update the module."

And if I click on Run Program, it says "Program line no. 0 is not defined".

Sorry, I'm really a stupid user cheesy

I did put everything (project file and images) in the application directory and I had to rename the images to remove all zeros at the beginning and they are named as follows

new1.bmp
new2.bmp
...
new10.bmp
new11.bmp
...
new100.bmp
etc...

And I am not using the latest version but the previous one from 22.4.2010 (as the latest requires net 4.0 which doesn't run on my WinME system). It took quite a bit of fiddling and a few error messages until I got it to work but I am sure I have seen none of the errors you report so perhaps you should be using the same version as I do if you use the project I uploaded as a basis for your trials.

Oh and btw, I've just realized you use the run program button when it is the start map button you've to click on to start the process. I am not sure what that run program button is about as it crashes the app when I try to use it here (I have just tried for the first time a few seconds ago hahaha), hopefully it doesn't work just because you are clicking on the wrong button.

Edit: the run program button also works for launching the process but only after a snapshot of the current state has been made (with the snapshot button).

Because it came in a 2nd beta upload smiley

Btw, I remember you printed some Mandelbulbs a while ago? How did you do that?

OK, not me blind then! Downloaded again, looks great!!! (see if you recognize the place from the attached image wink )
Having some troubles getting the same result as in the preview though...

Yes I love my printed bulbs! I had a friend on this forum do them for me, I could ask him how he got the right format for the printer, I remember he had some trouble with it too...
There is a thread somewhere about it...

Yep, the Medusa image

I will also see if I can find it (when I've got time) but I don't think there was any clear info about this, I will see if I can find his email...

Hey blob,

There are many versions of MVE-2 available for download, which one are you using?

I tried programs like Meshlab or Blender, it is incredible they don't have a function to load an image stack. Having to use ImageJ (=Fiji) or MVE-2 is a pain, they are not really user friendly and I can't make them work... sad

Any advice or step by step instructions appreciated!

I finally am on Vacation!

10 Days of no responsibility.  My employment is closed, and Lissa is out of state, and since this is the feature I have been waiting for and requesting since Day 1 of Mandelbulb3D, I'll be working on this.

Looking for the above mentioned software now.

I too wish importing these things was standard in 3D Apps as well.  Like Blender, the few commercial 3D Programs I own wont handle this sort of thing either.

But I'll find a way   afro

OK - minimal progress, but progress none the less!


Bigger: http://www.sockrateaze.com/stuff/step1.jpg

I used fiji  (first 32 bit windows exe file on the download page there in case version matters) and imported the voxel stack.  I tried a few different ways to export it - some made the same small files reported earlier.  But if I had the stack open and chose the 3D Viewer plug-in, then exported my obj, I got a big 120 MB file   smiley

But that file would not import to any of my 3D apps except the one modeling app I paid for, Hexagon   (well, Carrara is a modeling app too, but it does so much more, I think of it as an all-around 3D app!).

I can't export it from there though...  that just causes errors.

I think I was too ambitious and need to make a smaller voxel stack of a less complicated fractal, just to get the procedure down  (I used a 400 image stack, and set the 3D Viewer to pretty high resolution).  Still not sure if the viewer settings effect anything in the export.  But I'm done for today!  I tried every free 3D app and 3D Modeler I could find.  Only Hexagon imported the file.  

Hexagon goes on sale for $1.99 at Daz3d.com quite frequently, so if this turns out to be the only tool that works, it's a good bit cheaper than 3D Coat!

More tomorrow, so stay tuned...

Did you try Bryce ? I believe many of Terry Gintz' software users import into that - and often with files bigger than you stated wink

Though as I recall they normally use stl files.

Bryce  is from the same people who make Carrara and Hexagon, and yes - tried that too.  Byce does not handle stl files as far as I know.  Just the usual array of obj, 3ds, etc.

It's not the file size, it's something in the way Fiji creates the obj file.  I have routinely used obj's from Groboto (which can be 700 MB) in Carrara without choking it.  Here's one just to show that huge obj's work in these programs:



So I'm not sure why, but there is something very strange going on here...

Hmmm - I thought that just about all of them handled stl as it's the most generic and simplest format whereas "obj" is more proprietary and has undergone so many changes that not all implementations are the same.

e.g. our old "obj" files for 3D Studio from the 90's won't even load in the current version of 3D Studio !!

Interesting...

The current reality is that most of the 3D apps can't handle stl files, and up until now have never met an obj file they didn't like!  Even obj's over 1 GB!

obj format is only proprietary in it's binary form )used in Wavefront's Advanced Visualizer application and with the .mod file extension).  The .obj extension is ascii and not proprietary.

I checked my older versions of Carrara, and C6 could indeed export an stl, but not import it.  C7 and C8, as well as Bryce 6 & 7 - no go.

Very weird!

3D Studio has always been far too expensive for me to play with, much more than Maya or Cinema 4D - which have been called "affordable" by some with more money than me...

I have made some new progress though - it was actually the Volume Viewer - not the 3D Viewer - which had to be opened before a use-able obj could be made.  Got some in the 60 or so MB range that worked, but had an odd plane at the z-start and z-end positions which had to be deleted in a modeling program.  Will include screenshots in a post later - after I get a repeatable procedure laid out!  It has something to do with the rgb channels I think, because changing those settings actually made the difference between a tiny useless file and a reasonable 3D Model.

If anyone who knows what is going on could provide a repeatable procedure, let me know!
