SG Visualisation Contest20 October 2016
We have an internal contest on scientific
As soon as there are a few submissions, the winner is decided by the group. The entry is then printed in large format, put in a frame and shown in the lounge area of the Chair.
Here we present the latest entry, submitted by Vahan
It shows the network of citations between publications in the journals of American Physical Society, published under PACS 89. The network layout used is the ARF, developed internally at the Chair of Systems Design. The layout is nicely implemented in graph-tool, a powerful Python package for working with networks. The produced layout -- the coordinates of the nodes and links 3D -- are saved in a text file to be later used in Blender, a fantastic example of Open Source software for 3D graphics. A few additional lines of Python code imported the network into Blender (it is written in Python and is easily extendable) with spheres representing nodes and with thick rods for edges. At this point, what was missing from the shown picture were the materials (light-emitting for nodes, translucent for edges), lighting and camera effects (depth of field, chromatic aberration, barrel distortion, etc.).
