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  3dBAR online service users from the account management panel.
To register as the service user fill out  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  GitHub using the commands below: 

cd && 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'
  1. 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
  1. Near 350th line of the file find a following line: 

                d = '_%s_%s' % (d[2:], 'void_p')
  1. Add '\0' characters to the line to make it like below: 
                d = '_%s_%s\0' % (d[2:], 'void_p')
  1. Save the modified file.
  1. The bug should be fixed for now. Try running 3dBAR again. If this solution doesn't work - let us know.
