Python and PyOpenGL install on Windows Vista

OpenGL is usually used with C/C++ compiler. But, it's a little too much to me at this point of time. I looked for a interpreter and I found I can use Python which is very handy, free and platform independent.

Python 2.5.2 installation by refering Ponta's blog. This blog is very helpfull for me to use OpenGL on Python first time.

Environment:
Hardware: Sony VAIO notebook PC, VGN-SZ74B
CPU: Intel Core2 Duo T7300 2GHz
RAM: 3GB
OS: Windows Vista Home Premium

1. Download Python 2.5.2 Windows installer python-2.5.2.msi from http://www.python.jp/Zope/download/pythoncore

2. Double crick python-2.5.2.msi to start installation. You installed Python in C:\phyton25

3. Download glut, glut-3.7.6-bin.zip. Unzip and copy glut32.dll to both C:\WINDOWS\system and C:\WINDOWS\system32.

4. Doenload PyOpenGL, PyOpenGL-3.0.0b1.win32.exe. Double crick the file to install PyOpenGL.

5. Invoke MSDOS window in C:\phyton25. Make a sample program sample1.py by copying the following code. Then, type "python sample1.py" in MSDOS window. You can see a teapot diaplayed in a new window.

### sample1.py
### are totally ignored in HTML. I used   in the sample. Please replace   to real tab using text editor. Python is a tab or indent base language. It doen't run without right number of tabs.
