Introduction

Visvis is a pure Python library for visualization of 1D to 4D data in an object oriented way. Essentially, visvis is an object oriented layer of Python on top of OpenGl, thereby combining the power of OpenGl with the usability of Python. A Matlab-like interface in the form of a set of functions allows easy creation of objects (e.g. plot(), imshow(), volshow(), surf()).

Visvis ...

• is easy to use
• is cross-platform
• is lightweight
• is designed to be easily extendable
• can be used in scripts
• can be used in interactive sessions (like in IPython or IEP)
• can be embedded in (commercial) GUI applications
• requires Python 2.x, Numpy, pyOpenGl and a GUI backend.

How visvis works

With visvis a range of different data can be visualized by simply adding world objects to a scene (i.e. an axes). These world objects can be anything from plots (lines with markers), to images, 3D rendered volumes, shaded meshes, or you can program your own world object class. If required, these data can also be moved in time.

Online documentation is available for all classes and functions. Any questions can be asked in the visvis discussion group.
