I did not know that very useful thing. But now I do.
I've got an array S of shape (N, 6) with N >> 10 containing the
six components of a stress field given in N points.
I need to make a lot of computation of principal stresses, which are
in fact the eigenvalues of the stress tensors.
I'm using the basic code described below :
import numpy as n

It is already in matplotlib

This question gets asked about once a month on the mailing list.
Perhaps pnpoly could find a permanent home i
I have just started doing my tests using numpy and hdpy(
http://h5py.alfven..org/ ).
Hope either of these would give me what I need.

there is also pytables, which providers a nice numpy/HDF interface.

I am seeing all the OSS for this purpose but I would stick to use pure python
and the scene graph I am developing for the application. I already did some
test using pyOpenGL/python/wx.GLcanvas and a large data set of roughly 4000+
objects consisting nearly 1 million polygons using display lists
Did you consider VTK?
I've used it a *little*: Probably it contains all the structures you need,
along with c++ routines for I/O, manipulation and
(OpenGL) display, and a python interface.

This may have been an oversight. The docs directory moved out of the
source tree, so it needs to be added to the ins
Thanks for your reply ;-)
In fact, I was talking about the 1.20 release installer, which is not
including the numpy.i any more.
Is this numpy.i not any more part of the binary delivery/installer ?
Should I take it manually/directly from the SVN repository, instead of
beeing installed automatically

The docs dir has moved:

Hello,
Under windows, using the latest numpy 1.20 and Swig release, I can't find
anymore the numpy.i file.
I used to find it in numpy/doc/ in the release 1.04.
I tried to look some info the web without any success.
Thanks for you help,
Cheers,
Nicolas.

Hi,
I have never used numpy in my python applications until now. I am writing a
python/openGL based tool to manipulate 3d geometrical data(meshes, curve,
points etc.) I would be using numpy to store these objects(vertices, edges,
faces, index etc.) at run time. One of my major concern is numpy'
