Try <a href="http://code.google.com/p/gameobjects/" rel="nofollow noreferrer">gameobjects</a> -- it's a math library that includes Python classes for matrices and vectors, along with methods for transformations. I think it will provide most (if not all) of what you need, plus it's pure Python so you can modify it if you need to.

It uses numpy for speed.
The aim is to provide a pure python 3D maths lib.

I'm avoiding external libs because I'm sick of having to follow complex software installs. Python should be easy.

The implementation isn't always the best, but it includes quaternions as well as the standard matrix and vector types. I've used it for tools on a couple commercial game projects.

i'm looking for a 3d math library in python or with python bindings.

it needs to handle rotation, translation, perspective projection, everything basically. 

what im NOT looking for is a library aimed at drawing on the screen, googling for hours only led to 3d libraries bent on rendering something to the screen. i dont want any visualization whatsoever, all i need is to be able feed a library x,y,z coordinates and recieve the x,y screen coordinates. 

i dont mind if its a visualization library, as long as it can be used without rendering anything to the screen.

is there anything like this for python?

Edit:
please dont recommend scipy/numpy as they arent aimed at 3d math but at math in general, they look like great tools if i wanted to build the library myself, which i dont. thanks.

3d Math Library For Python

Python

我正在寻找一个3d数学库的python或与python绑定。它需要处理旋转，平移，透视投影，基本上所有的事情。我没有在寻找一个旨在屏幕上绘图的库，谷歌搜索了几个小时只会导致3d库一心想要在屏幕上渲染一些东西。我不想要任何可视化，我所需要的是能够提供一个库的x，y，z坐标和接收x，y屏幕坐标。我不介意它是一个可视化的库，只要它可以在不向屏幕渲染任何东西的情况下使用。python有没有类似的东西？编辑
