A Study of Uncertainty Visualization for 3D Scalar Data



PDF, ebook, epub (ePub, fb2, mobi)

3D scalar data visualization has been well accepted as a powerful means to allow scientists to explore large data sets, and to present their results to a wider audience. However, most of these visualization techniques have been designed on an assumption that the 3D scalar data to be represented are free from uncertainty. This is rarely the case in the real world, as uncertainty is pervasive in 3D scalar data and there is a growing need to depict the uncertainty in 3D scalar data visualization. Overlooking such depictions in 3D scalar data visualization could result in unfaithful representation of the 3D scalar data, and leave the visualization running in a risk that misleads viewers' interpretation, conclusions or even decisions from the 3D scalar data. Therefore, the topic of this book is about the study of how to efficiently represent uncertainty that is associated to the 3D scalar data in 3D scalar data visualization. This is also known as uncertainty visualization for 3D scalar data, which is currently a hot research topic in the visualization community.

tion we are normally presented with a dataset assuming scalar data for simplic . Therefore this thesis focuses on the study of uncertainty visualization in 3D scalar data and we seek to create better uncertainty visualization techniques as well as to find out the advantagesdisadvantages of those stateoftheart uncertainty visualization techniques. Be able to visualize uncertainty is often neglected but it is a challenging topic. F 1 INTRODUCTION I . A Study of Uncertainty Visualization for 3D . Because our uncertainty is also represented as a 3D scalar field we have the opportunity to map field values to color and uncertainty values to opacity and experiment with different transfer functions. When we see a data point drawn in a specific location we Figure 16.4 Key concepts of statistical sampling.
