VisIt Python Interface Manual —This document describes how to use the VisIt Python Interface. It covers in detail all of the functions and objects provide by the VisIt Python Interface and also gives some background on scripting with Python and common patterns that can be used when creating scripts for VisIt.
Getting Data Into VisIt (3.61 MB pdf) Example source code (50 KB tar.gz)—This document describes how to get data into VisIt using three different approaches: (1) writing data files that VisIt can read, (2) creating a database reader plug-in, and (3) instrumenting a simulation code to talk directly to VisIt so no files need to be written. This manual covers in detail most aspects of the three approaches to getting data into VisIt and also provides complete working source code examples.
