Large Scene Support
The Large Scene Support topics covered in this project are:
- Hierarchy Generation
For occlusion culling and LOD selection special hierarchies and data structures
are required, which differ considerably from the scenegraph hierarchy. In this
workpackage algorithms for maintaining such hierarchies for static and dynamic
parts of the scene are developed. For further information take a look at Institute
for Computer Graphics, University of Technology Braunschweig.
- Occlusion Culling
In conjunction with hierarchy generation modern occlusion culling techniques
are being developed to support large and complex scenes. By the use of
occlusion culling parts of the scene hidden to a given viewpoint are detected
and excluded from the rendering process. Thereby the reduced polygon count
leads to a faster visualization. More information is available at WSI/GRIS,
University of Tübingen.
- Models & APIs for LOD Selection
- Objekt-Optimization / Netcompression
- Impostors
One approach to speed up the display of very complex scenes is replacing objects
that are further away with images. These images can be calculated in a
preprocess or at runtime. In this package methods to select suitable objects and
to create the replacement images are developed.
