Excellent--and a 3D rotation matrix is 3x3--so the list can remain n*3.
Now the question is how to apply a rotation matrix to the array of vec3?

Thanks Josef. In that case I'm good to go.

Hi all,
Here are some requests / things I think need to be done before a 1.4.1 RC1
can be put out.
1. Bump up the version to 1.4.1
2. Update the release notes, including an explanation of why 1.4.0 was
pulled.
3. Patrick and I need info on how to upload to Sourceforge. David or Jarrod,
can you

Hi all,
We are using at the moment a c extension which should manipulate masked
arrays.
What we do is to fill the masked array with a given value (say 65535 if we run

Hi,
We're talking map projections, so that means that the values will move around,
including masked ones...
So filling the array with a given value is a way of projecting the array and
the
mask in one shot...
OK then. Just make sure
Thx David,
Maybe i will have to try that as a temporary fix. But in the long run i do want
to build my own Python.

This is how I always do it:
In [1]: import numpy as np
In [3]: tmat = np.array([[0., 1., 0., 5.],[0., 0., 1., 3.],[1., 0., 0.,
2.]])
In [4]: tmat
Out[4]:
array([[ 0., 1., 0., 5.],
[ 0., 0., 1., 3.],
[ 1., 0., 0., 2.]])
In [5]: points = np.random.random((5, 3))
Excellent--this setup works perfectly! In the areas I was concentrating on,
the the speed increased an order of magnitude.
However, the overall speed seems to have dropped. I believe this may be
because the heavy indexing that follows on the result is slower in numpy.
Is this a correct
