Python GLUT. Learn how to use python api pyglet. A small working example of vispy, along with some notes - vispy0. Because all OpenGL implementations since 2. While the GUI backends are essentially interchangeable, the notebook backend is more restrictive in its capabilities and some features are not currently available with it. This is the auto-generated API documentation for the vispy library. Finally, there is always the option to resort to low-level tools like OpenGL, which no sane scientist will ever do. We also provide an on line documentation, examples and datasets and can also be downloaded from PyPi. Github Repo: https. submit (download, found [d], d, index) That's it; a trivial change, and two lines less than your existing code, and you're done. VisPy is a quite young library, with a mature mid-level object-otriented wrapper to openGL (that they called gloo, I guess it is GL object-oriented) and the early stages of a high-level wrapper quite similar to MayaVi in the functioanlity.
