A python interface to Tecplot 360

Project description

The pytecplot library is a high level API that connects your Python script to the power of the Tecplot 360 visualization engine. It offers line plotting, 2D and 3D surface plots in a variety of formats, and 3D volumetric visualization. Familiarity with Tecplot 360 and the Tecplot 360 macro language is helpful, but not required.

Documentation

The full documentation is here: http://www.tecplot.com/docs/pytecplot

Quick Start

Please refer to the documentation for detailed installation instructions and environment setup. The short of it is something like this:

pip install pytecplot

Linux and OSX users may have to set LD_LIBRARY_PATH or DYLD_LIBRARY_PATH to the directories containing the Tecplot 360 dynamic libraries. Please refer to the documentation at http://www.tecplot.com/docs/pytecplot for detailed information regarding setup and use. In addition, the web page http://www.tecplot.com/support/faqs/pytecplot contains a list of answered questions you may have about PyTecplot in general.
