Lab Exercise 12

Due: never!!!

Image processing

1. Install PIL, the Python Image Library. On Fedora:

   yum install python-imaging
   

   On Ubuntu:

   apt-get install python-imaging
   

2. Google `PIL tutorial' and try out some of the examples in the tutorial. You will need to provide your own image files, assuming that you don't have lena.ppm, which is a ubiquitous and notorious image that has been used to test image processing algorithms (Google `lena' for details).

Games!

1. Install Pygame. On Fedora:

   yum install pygame
   

   On Ubuntu:

   apt-get install python-pygame
   

2. Annoyingly, the distribution doesn't include the examples, so I have created a zip file that you can download from http://wb/sd/code/pygame-examples.zip. Put it in your Python directory and then

   unzip pygame-examples.zip
   

   It should create a directory named examples. Run a few of the examples and then read the Pygame tutorials at http://www.pygame.org/docs/tut/intro/intro.htmland http://www.pygame.org/docs/tut/chimp/ChimpLineByLine.html.

   The second tutorial explains chimp.py, which is in the examples directory.

3D Graphics

1. Install VPython. On Fedora:

   yum install visual-python
   

   On Ubuntu:

   apt-get install python-visual
   

   You can test it by running some of the examples. On Fedora:

   cd /usr/share/doc/visual-python-3.2.9/examples/
   python stonehenge.py
   

   On Ubuntu:

   cd /usr/share/doc/python-visual/examples/
   python stonehenge.py
   

   The documentation is available from http://www.vpython.org/.

2. The examples should give you an idea of what is possible. Choose an interesting one, make a copy, and play around with it.
