Uncertainty visualization in the VisIt visualization environment
Andrew Foulks, R. Daniel Bergeron · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2008
Visualization and analysis of very large datasets remains a significant challenge to the visualization community. Scientists have tried various techniques to deal with large data. Multiresolution data models reduce the size of the data using techniques such as mesh decimation, wavelet transformation, or data compression. The low resolution representation raises issues concerning the authenticity of the data at its resolution level. We address this issue by presenting our extensions to the VisIt visualization environment that enable the scientist to visualize both multiresolution data and the uncertainty information associated with the lower resolution representations of the data.
