python 3D visualization and graphics [closed]

问题:

I am looking for Python compatible 3D graphics. Mostly I would like to be able to draw lines and view them in 3D. I literally have no experience in this area and am looking for knowledge and tutorials.

I learn programming best by experimentation. So which packages do I need to do 3-D graphics? I really enjoy using emacs, so if you have those suggestions as well that would be awesome!

In summary:

1. Which packages do I need for 3D graphics in python.
2. Note that I use Ubuntu 12.04 LTS and emacs 24.3

The most common way to integrate realtime 3D graphics is using the OpenGL library. OpenGL and realtime graphics is a big topic, but focusing on something like drawing 3D lines should not be too difficult. Bindings exist for python http://pyopengl.sourceforge.net/

GLUT - is probably the best for providing X platform windowing and context setup, and is included in the mentioned bindings.

OpenGL - there are several versions, for your application, immediate mode, legacy, is probably acceptable.

Here are some links for learning - Don't feel obligated to read them all - pick the topics that are relevant to you.

The easiest way for 3D visualization in Python is VPython.

For example, to draw a curve in the shape of a square, it's just:

square = curve(pos=[(0,0),(0,1),(1,1),(1,0),(0,0)])

This is vastly easier than MayaVI, VTK, OpenGL, etc.

Another easy option is matplotlib's 3D graphics. It's better on the quantitative details, but not as simple, fast, and interactive for the 3D part.
