Second Quarter Project Proposal
due August 9, 1999

I am still planning on programming a 2d bouncing ball simulation.
Here are more details on my ideas.

Shape to bounce = circle
Shape spinning = yes
Design in shape = yes
Design to be used = 2 or 3 letters of text (My initials, or a number)
Obstacles = yes, other bouncing balls (up to 25)
Bounding shape for bouncing ball = rectangle

Extras if I have time
---------------------
- ability to place any 2 letters into the bouncing ball(s)
- ability to apply an acceleration factor to the ball(s)
- different bounding shapes for the bouncing ball(s)

Class concepts excercised by my proposed project
------------------------------------------------
Matrix by Matrix multiply
Matrix by vector multiply
Rotation
Translation
Midpoint circle generation algorithm
displaying simple 2d characters
2d Object modelling
Collision detection

See attached page for hand drawing of my bouncing ball.

I am still planning on most of the same details that I explained in
the first project description.  The one exception is explained below.

I will still experiment with using matrix transforms to simplify the
plotting of the bouncing ball, but I see the difficulties that may
arise from this technique.  It will be difficult to calculate the
collisions of two or more bouncing balls using this techinque.  I may
also have troubles reflecting the entire bouncing ball over a line.
This technique will have the undesired side effect of making the text
within the bouncing ball also reflect.  Because of these difficulties,
I plan on altering the trajectory of the bouncing ball by changing
the formula for the line on which it is travelling at each collision.
