Re: [Matplotlib-users] [Numpy-discussion] glumpy: fast OpenGL numpy visualization + matplotlib integration

[Nicolas Rougier]

Well, I've been starting working on a pyglet backend but it is  
currently painfully slow mainly because I do not know enough of the  
matplotlib internal machinery to really benefit from it. In the case  
of glumpy, the use of texture object for representing 2d arrays is a  
real speed boost since interpolation/colormap/heightmap is made on the  
GPU.


Concerning matplotlib examples, the use of glumpy should be actually  
two lines of code:


from pylab import *
from glumpy import imshow, show

but I did not package it this way yet (that is easy however).

I guess the main question is whether people are interested in glumpy  
to have a quick & dirty "debug" tool on top of matplotlib or whether  
they prefer a full fledged and fast pyglet/OpenGL backend (which is  
really harder).

Hi all,

glumpy is a fast OpenGL visualization tool for numpy arrays coded on
top of pyglet (http://www.pyglet.org/). The package contains many
demos showing basic usage as well as integration with matplotlib. As a
reference, the animation script available from matplotlib distribution
runs at around 500 fps using glumpy instead of 30 fps on my machine.

(it does not require installation so you can run demos from within the
glumpy directory).

Hi Nicolas,

This is technically called OpenGL backend, isn't it? It is nice that  
integrates with matplotlib, however 300 hundred lines of code indeed  
a lot of lines for an ordinary user. Do you think this could be  
further integrated into matplotlib with a wrapper to simplify its  
usage?
