| Abstract: |
|
This tutorial will initiate with an overview of Scientific Visualization usage scenarios: data exploration, quantitative analysis, comparative analysis, visual debugging, and communication of results. We will give introductory notions of the visualization pipeline, with examples from at least two different open-source softwares. We will then focus on one of them, VisIt, to give attendees concrete examples and hands-on practice of the application. The VisIt tool has a client-server design for remote visualization, with a distributed memory parallel server. VisIt is used to visualize and analyze simulation results on many of the world’s top supercomputers. We will show how VisIt supports the visualization pipeline paradigm, covering all the usage scenarios presented in introduction, moving from basic principles, covering several special topics, and intermediate-level challenges. The last portion of the tutorial will discuss how to do VisIt development, including writing new database readers, writing new operators, and how to couple VisIt with simulations executing on remote computers, to enable in-situ visualization. |
