Global Flightdata Animation

After a few still renderings from the FL24 Project I wanted to see where all the flights where going and started to render animations in OpenGL which I then postprocessed in Blender. Global Flightdata Timelapse Density Heightmap over Germany After seing how…

24 Hour Flightdata Visualization

What is flying above that we can't see ? One day I asked myself the above question and wanted to get an answer to it so I started this project. But where to start , I had to gain knowledge about various aeronautic topics despite knowing how a plane works in…

NetArgos - Live Network Visualisation

NetArgos is an live visualization tool to display open network connections via OpenGL. It was born due to the thought that I wanted to see where on the world my data comes from and/or goes to. https://github.com/Kabelmaulwurf/NetArgos.git…

Metaballs in 806 bytes

Tri-Meta was a short try to create a demo purely in assembly without OpenGL/GLSL thus using purely FPU instructions and writing the result directly to the video memory. The resulting animation consists of 3 glowing Metaballs circling over a munching-square pl…

Social Network Visualization
