ParaView is a powerful open-source, multi-platform scientific data analysis and visualization tool that enables the analysis and visualization of extremely large datasets. The ParaView application provides you access to a distributed architecture that can be seamlessly leveraged by your desktop or other remote parallel computing resources. But this is only part of ParaView’s advantages.  It also provides you with an extensible framework composed of  a collection of tools and libraries for various applications including scripting (using Python), web visualization (through ParaViewWeb), or in-situ analysis (with Catalyst).

This course will allow you to look “under the hood” of the ParaView application and provide you with a detailed understanding of ParaView’s framework as well as how to customize it in order to better suit your visualization needs.
