Hi, is there a numpy-thonic way, e.g. function, to find the 'nearest value' in an array? example:
np.find_nearest( array, value )
thanks in advance!

I know that Terminal is…

I'm trying to batch up a bunch of vertices and texture coords in an interleaved array before sending it to pyOpengl's glInterleavedArrays/glDrawArrays. The only problem is that I'm unable to find a suitably fast enough way to append data into a numpy array.
Is there a better way to do this? I…

The "vectorizing" of fancy indexing by Python's numpy library sometimes gives unexpected results. For example:
import numpy
a = numpy.zeros((1000,4), dtype='uint32')
b = numpy.zeros((1000,4), dtype='uint32')
i = numpy.random.random_integers(0,999,1000)
j = numpy.random.random_integers(0,3,1000)
a[i…
