Hi all, I am exited to announce version 1.3 of Visvis, the object oriented approach to visualization. Website: http://code.google.com/p/visvis/ Discussion group: http://groups.google.com/group/visvis/ Documentation: http://code.google.com/p/visvis/wiki/Visvis_basics The largest improvement is the Mesh class to represent triangular and quad meshes and surface data. The Axes class got a property to access 8 different light sources. These improvements enable numerous new possibilities to visualize data using Visvis. Further changes include the introduction of polar plotting and 3D bar charts. For a (more) complete list of changes see the release notes <http://code.google.com/p/visvis/wiki/releaseNotes>. === Description === 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? <http://code.google.com/p/visvis/w/edit/OpenGl>, thereby combining the power of OpenGl?<http://code.google.com/p/visvis/w/edit/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()). Regards, Almar
