Extending the scene graph with a dataflow visualization system
Michael Kalkusch, Dieter Schmalstieg · 2006
Data ow graphs are a very successful paradigm in scientific visualization, while scene graphs are a leading approach in interactive graphics and virtual reality. Both approaches have their distinct advantages, and both build on a common set of basic techniques based on graph data structures. However, despite these similarities, no unified implementation of the two paradigms exists. This paper presents an in-depth analysis of the architectural components of dataflow visualization and scene graphs, and derives a design that integrates both these approaches.The implementation of this design builds on a common software infrastructure based on a scene graph, and extends it with virtualized dataflow, which allows the use of the scene graph structure and traversal mechanism for dynamically building and evaluating dataflow.
