		       Practicing Transformations
			 Due: January 27, 2009
		       Submission: Mail to the TA

This assignment aims to give you a little fun by playing with the
transformations to study their effects, the rules for compositing them,
how things can go wrong and how they can go right, etc!

To do:

1. Download the tool from the course pages:

	  192.168.36.158/~pjn/CS3500.html

   You will see the link for the course on the first page itself.

2. The tool runs on Linux, needs Qt3.3, etc. It should run directly
   under most of your Linux systems as it is compiled for Fedora Core 2.
   If you have trouble, the object files can be given to you. Contact the
   TAs for the details.

3. The tool allows for loading a number of 2D objects and subjecting
   them to (upto) 5 transformations. Each of the tranformations could
   be transation/rotation/scaling/matrix. You will be asked to specify
   the parameters.

4. Your job is to have fun by playing with different transformations,
   their combinations, etc. Study what happens with rotation is followed
   by translation and vice versa. The transformation part of the code
   appears at the right side of the menu window for your understanding.

5. Try out the matrix transformations by themselves with different
   affine matrices.

6. Try out the matrix transformation with a few purely projective
   matrices (i.e., those with non-zero entries in the last row, first
   2 columns). See the impact on the shape of even moderately
   projective matrix.

7. Exercise different options of the tool. Have fun. Learn about the
   transformations. Reflect on the effects and make sure you understand
   what is happening. Do this for 30 minutes to 1 hour, and cover
   different parts.

8. In the end, "Quit" the tool. A file with your rollnumber.sav will
   be in your directory. This contains a coded log of all that you did
   with the tool including your machine id, the times, etc.

9. Email this file to the TA. You will be graded on how much you played
   with the tool.

Have fun!
