Visvis - the object oriented approach to visualization

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/Matplotlib-like interface in the form of a set of functions allows easy creation of objects (e.g. plot(), imshow(), volshow(), surf()).

Status

Visvis has been relatively stable for several years. I am still maintaining it trying to make sure it keeps working, but do not plan on making any major changes. Visvis will not make use of modern OpenGL. It's API might be a bit idosyncratic (e.g. methods are UpperCamelCase) because I started working on Visvis before I knew about PEP8.

See Vispy for a similar (but more modern) visualization library.

I am now working on PyGfx, which is better in almost every way. A bit lower level though, but people are starting to build higher level API's on top of it ...

Installation

Visvis is cross-platform and runs on Python 2.x and Python 3.x. It depends on numpy, pyopengl.

Installation is best done via pip (pip install visvis) or conda (conda install visvis).

You also need a GUI backend, either of these will do:

  • GLFW -> recommended, runs on asyncio, install using pip install glfw
  • Qt: PySide6, Pyside2, Pyside, PyQt5, or PyQt4
  • Wx
  • GTK
  • FLTK

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.

Example

Click on the figure to see the code and how one can interact with the figure.

Documentation

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

At EuroScipy 2012, I gave a talk about Visvis. The long version of the presentation can be seen here.

Visvis - the object oriented approach to visualization
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/Matplotlib-like interface in the form of a set of functions allows
easy creation of objects (e.g. plot(), imshow(), volshow(), surf()).
Status
Visvis has been relatively stable for several years. I am still maintaining it
trying to make sure it keeps working, but do not plan on making any major changes. Visvis will not make use of modern OpenGL. It's API might be a bit idosyncratic (e.g. methods are UpperCamelCase) because I started working on Visvis before I knew about PEP8.
See Vispy for a similar (but more modern) visualization library.
I am now working on PyGfx, which is better in almost every way. A bit lower level though, but people are starting to build higher level API's on top of it ...
Installation
Visvis is cross-platform and runs on Python 2.x and Python 3.x. It
depends on numpy, pyopengl.
Installation is best done via pip (pip install visvis) or conda (conda install visvis).
You also need a GUI backend, either of these will do:
  • GLFW -> recommended, runs on asyncio, install using pip install glfw
  • Qt: PySide6, Pyside2, Pyside, PyQt5, or PyQt4
  • Wx
  • GTK
  • FLTK
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.
Example

Documentation
The docs are on the wiki.
Online documentation is available for all
classes and
functions. Any
questions can be asked in the visvis discussion
group.
At EuroScipy 2012, I gave a talk about Visvis. The long version of the
presentation can be seen here.
