NG3DV

☛ Position: Software Architect & Lead Developer
☛ Schedule: Jan. 2009 - Dec. 2011
☛ Client: German Aerospace Center (DLR)
☛ Team size: 2 people

NG3DV was built as the successor to the SatViz project described below. The goal was to re-implement the simulation system with a unified and simplified architecture, using updated technologies to improve the overall robustness, usability and performance level.

The project was structured as a framework that could be extended with different plugins. It provided all important sub-projects supported in SatViz, and was also extended with more sub-projects such as:

• Mars Express,
• TET satellite,
• UAV simulator

This software also introduced many new features such as:

• Advanced shader effects,
• Earth map providers integration,
• Large scale environment simulation,
• Multi-window display, etc.

• I initiated and defined the complete software architecture.
• I upgraded the OSG based 3D engine created for SatViz and integrated it into a wxWidget based application.
• I gathered significant experience with:
  • GUI development,
  • Networking protocols,
  • Project management,
  • OpenSceneGraph framework & GLSL shaders,
  • Online Earth Map services
• I implemented advanced features on the 3D engine such as:
  • Retrieval of Microsoft Virtual Earth imagery and NASA World Wind elevation layers,
  • Complex shading effects (atmospheric scattering, realistic ocean, etc)
  • Orbit propagation and footprint projection on Earth,
  • Video streaming support with ffmpeg
  • Integration in web page with a java applet
  • License management and encryption

⇒ The NG3DV software replaced the SatViz installations and was used during many years for public demonstration and satellite monitoring. This re-newed system overpassed initial expectations and offered astonishing new capabilities such as handling more than 1000 satellites with precise positioning concurrently.
