"The Use of Volume Scene Graphs in Very Large Dataset Visualization"
Professor Min Chen & Dr David Chisnall, Computer Science, University of Wales, Swansea. Friday, 23rd June 2006, 1400 to 1500 pm British Summer Time ESNW Access Grid, Room 1.10, Kilburn Building The concept of volume scene graphs provides an elegant means for combining multiple datasets into a visualization in a constructive manner. In this talk, the speakers will present the algebraic framework of volume scene graphs, describe how different types of datasets (e.g., volume, point clouds) are combined into a volume scene graph, and discuss the relative merits of discrete ray tracing in rendering volume scene graphs. They will consider the challenges in modelling and rendering very large datasets in a complex volume scene graph, and examine several methods for out-of-core data management. In particular, they will highlight the use of the knowledge-based approach, which minimises the needs for hard-coding application-specific logic into a visualization system.
