[PyOpenGL-Users] numpy/Numeric vs. numarray with glDrawPixels

[Tim H. <hi...@re...>]

Hello All,
    I have written a small ap to output video coming from arrays of type =
'w' in numpy and type 'UInt16' in numarray.  I send the arrays to =
glDrawPixels using the tostring() method in both array libraries.  This =
is all running inside wxPython and the looping is occuring through calls =
from OnIdle.  In both cases, this works nicely, but interestingly, the =
framerate in the numarray version is 30 fps (the max allowed from the =
video frame source) while the exact same code using Numeric runs at 15 =
fps.  I find this strange because otherwise, I have found Numeric to be =
faster than numarray.  Does anyone have any idea why this might be =
happenning.  Is there a better way than tostring() to pass 2d arrays =
from Numeric to glDrawPixels.  I noticed a post on that a while back, =
but no follow up on a solution.

thanks,
tim
