OpenSG PLUS

An Open Source Realtime-Rendering API
as standard for virtual and augmented reality applications.

OpenSG PLUS is a project that is funded by the German Ministry for Research and Education (BMBF[1]). In this three-year project 9 german research institutions (universities and independent reasearch groups) working in the field of 3D computer graphics are cooperating to enhance OpenSG[2] (Open Source Scenegraph) by innovative and trendsetting functionalities thereby supporting the OpenSG Forum through R&D work for new application areas.

Within the scope of the work package High-Level Primitives at the institute for computer science, University of Stuttgart a module for volume visualization is being developed under the direction of Prof. Dr. Th. Ertl. Based on this module the integration of volumerendering into VR- and AR-applications will be possible at very low cost.

Aims of the Volumerendering work package

  • semitransparent direct volumerendering
  • rendering shaded isosurfaces
  • combined rendering of volume data sets and arbitrary OpenSG-shapes
  • support for time varying volume data
  • restriction of volume rendering to parts of the data set via clipping
  • Level-Of-Detail volume visualization

    •  
  • cross-plattform design to the widest possible extent
  • hiding as many details as possible for application developers
  • flexibility for future API-developement

    • Demo Application - Compiled for SuSe Linux
