Is OpenSceneGraph an option for ESVS displays?
Niklas Peinecke · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2015
Modern Enhanced and Synthetic Vision Systems (ESVS) usually incorporate complex 3D displays, for example, terrain visualizations with color-coded altitude, obstacle representations that change their level of detail based on distance, semi-transparent overlays, dynamic labels, etc. All of these elements can be conveniently implemented by using a modern scene graph implementation. OpenSceneGraph offers such a data structure. Furthermore, OpenSceneGraph includes a broad support for industry-standard file formats, so 3D data and models from other applications can be used. OpenSceneGraph has a large user community and is driven by open source development. Thus a selection of visualization techniques is available and often solutions for common problems can be found easily in the community’s discussion groups. On the other side, documentation is sometimes outdated or nonexistent. We investigate which ESVS applications can be realized using OpenSceneGraph and on which platforms this is possible. Furthermore, we take a look at technical and license limitations.
