[[PageOutline(2-4,, inline)]]

----

== Getting the code ==
It is assumed that the main directory dedicated for 3dBAR is `/home/$USERNAME/3dbar`.
if you want to install it in another directory, replace `3dbar` with the desired path.

The latest stable version of 3dBAR software is available to [http://service.3dbar.org 3dBAR online service]
users from the account management panel.\\
To register as the service user fill out [http://service.3dbar.org/register the 3dBAR service registration form].
Then you will also be able to download 3dBAR directly using the link provided via email.

Unzip the file to your home directory and go to the 3dBAR directory:
{{{
mkdir ~/3dbar; unzip 3dbar.zip -d ~/3dbar ; cd ~/3dbar;
}}}

You can also fetch the latest development version from [https://github.com/pmajka/3dbar GitHub] using the commands below:

{{{
mkdir -p 3dbar && cd 3dbar && git clone https://github.com/pmajka/3dbar.git .
}}}

The directories have the following purposes:
  * **bin**: Holds all executable files, atlas parsers and auxiliary scripts
  * **lib**: Holds the 3dBAR api
  * **atlases**: Directory, where the source data, //CAF datasets// and reconstructed models are stored. Each dataset (denoted as DATASET_NAME) contains the following subdirectories:
    * atlases/DATASET_NAME/src : Here the source data is located. It can be placed manually by a user or downloaded from internet depending on a particular parser. 
    * atlases/DATASET_NAME/caf : This is the directory where a CAF dataset is generated by specific parsers.
    * atlases/DATASET_NAME/reconstructions : The directory for reconstructed models.

Then follow instructions from `README` file to verify if the installation was successful.

== Troubleshooting ==
=== Segmentation fault in Ubuntu 11.10 ===
If the reconstructor crashes like that (numbers can vary):

{{{
$ ./3dbar.sh
./3dbar.sh: line 17:  2296 Segmentation fault      python bin/reconstructor/gui.py
}}}
  
the reason can be a bug in the 'python-vtk' package installed in your system.
Unfortunately there is no automated way to fix it - you have to do it manually:

1. Find a file named 'wxVTKRenderWindowInteractor.py'. It can be located
   in '/usr/share/pyshared/vtk/wx/' directory or in similar location:
 
{{{
$ find / -name 'wxVTKRenderWindowInteractor.py'
}}}

2. Edit the file with your favourite ASCII editor. In the example editor 'vim'
   is used and it is assumed that the path to the file is
   '/usr/share/pyshared/vtk/wx/wxVTKRenderWindowInteractor.py':
 
{{{
$ sudo vim /usr/share/pyshared/vtk/wx/wxVTKRenderWindowInteractor.py
}}}

3. Near 350th line of the file find a following line:
 
{{{
                d = '_%s_%s' % (d[2:], 'void_p')
}}}

4. Add '\0' characters to the line to make it like below:

{{{
                d = '_%s_%s\0' % (d[2:], 'void_p')
}}}

5. Save the modified file.


6. The bug should be fixed for now. Try running 3dBAR again. If this solution
   doesn't work - let us know.
