SatViz

☛ Position: 3D Developer & Modeler
☛ Schedule: May 2005 - Dec. 2008
☛ Client: German Aerospace Center (DLR)
☛ Team size: 4 people

SatViz was a real time satellite simulation tool with 3D visualization support. This software was initially designed for space industries simulation/visualization and provided simulation for the following satellites and ISS components:

• TerraSAR / TandemX
• SatcomBW
• International Space Station (ISS global visualization/positioning)
• Columbus / Biolab (extended ISS module visualization)
• ESA Automated Transfer Vehicle (ATV)

The software was then extended to simulate other systems, such as an OIL plant, or a F1 racing car.

• I was responsible for creating the 3D simulation environment primarily used for spatial missions modeling.
• I designed and implemented the 3D engine based on OpenSceneGraph.
• I gathered significant experience with:
  • C++ code,
  • 3D space algebra (matrices, quaternions, transformations),
  • OpenGL pipeline in general,
  • OpenSceneGraph framework,
  • 3D Modeling,
  • SCons build framework
  • Java code
• I interacted actively with the OpenSceneGraph community, producing plugins for OSG to:
  • Read SGI images,
  • Read BIL elevation data format,
  • Read GZ compressed files
• Got multi-platform experience: working with Visual Studio on Windows and Eclipse on Linux
• I optimized multiple 3D models with 3DS Max to make them “3D engine friendly”:
  • Columbus, ISS, NASA Shuttle, LTS, SatcomBW, TerraSAR-X, etc.
• I designed many classes/systems using UML diagrams (generated with BOUML).
• I created Windows installer construction scripts (with NSIS).

⇒ The SatViz software was used successfully for public demonstrations purposes for many years at DLR.
