[matplotlib-devel] OpenGL backend with Galry

2012-11-15 Thread Cyrille Rossant
Hi all, I am developing a high-performance interactive visualization package in Python based on PyOpenGL (http://rossant.github.com/galry/). It is primarily meant to be used as a framework for developing complex interactive GUIs (in QT) that deal with very large amounts of data (tens of millions o

Hello Ian, Thank you for your second proposition ; I find it very interesting in fact. (But beware that, as I do not feel able to do this on my own, your code exemple / guidance would be needed for sure... ) I will have a look at http://matplotlib.org/devel/index.html I think your idea of having

Yep, I'm still developing some OpenGL technics to provide both nice and fast rendering and I hope to be able to help the writing of a GL backend for matplotlib next summer (provided we get a GSoC student for the project). So far, my main concern is that for efficient rendering using OpenGL, yo

OK so it seems that integrating any efficient OpenGL rendering code in matplotlib as a backend is much more complicated than what I thought. > I'm guessing with galry, you push the user-coordinates to the graphics > card, then as the user is interacting, you're changing the transforms > and re-ren
