Getting the Framework and examples

Downloading from SVN

Go to an empty directory if possible and execute the following commands:

$ svn checkout http://scopiavf.googlecode.com/svn/trunk/ scopiavf
...
$ svn checkout http://labviz.googlecode.com/svn/trunk/ labviz
...
$ cp labviz/bitbroker/main/* labviz/gltree/main/* labviz/hello/* .

Last cp copies the main scripts of the examples to the root dir so we can execute them from there (which is the right place).

Download a snapshot

You can go to the downloads section (http://code.google.com/p/scopiavf/downloads/list) and get the latest snapshot of the framework and examples. Everything will be ready to execute them.

Requirements

Before you execute anything, you will need:

• PyOpengl: http://pyopengl.sourceforge.net/ in debian apt-get install python-opengl
• Numpy: http://numpy.scipy.org/ in debian apt-get install python-numpy
• PIL: http://www.pythonware.com/products/pil/ in debian apt-get install python-imaging

For gltree you will also need lxml: http://codespeak.net/lxml/ in debian apt-get install python-lxml. Now you can go and execute the examples:

Hello World

$ ./hello_glut.py

Don't expect anything from this. Just the basic hello world program.

Bitbroker

$ ./bitbroker_glut.py

This example is a visualizer of players and transactions between them over time. The transactions are those curves inside the circle. You can move in time using the slider on the bottom of the window.

GlTree

$ ./gltree_glut.py

This is a 3D version of a treemap. It visualizes an xml tree located at example.xml. Go and click in the boxes to expand the branches.
