1. MMA2 final project Steven Hunneman & Peter Fekkes BILLIARDS : A real-world example in a virtual environment

2. Project Goals Design and build a billiards game in dlp

3. The environment A Billiards table Three balls A Billiards cue Four table legs

4. Use of the axes The table uses the X- and Z-axis

5. Rules of (our) “libre” Billiards Rules for all balls Rules for the cue ball Use of the Billiards cue

6. Velocity of a ball Velocity decreases in a liniair way Initial speed when cue ball is played is constant

7. Proximity of a ball The radius of the ball is the distance for the proximity

8. Using the Billiards cue Only the cue ball has a proximity sensor for the Billiards cue

9. The edges of the table Each ball has a proximity sensor for other balls Each ball has a proximaty sensor for the edges of the table

10. Collision (1) A ball collides with a ball in rest

11. Collision (2) Two balls hit eachother in a straight line or:

12. Collision (3) Two balls hit eachother under an angle

13. The View Point The viewpoint of the (only) player is at a fixed height

14. Restrictions of our game Only one player No effects No friction (edges, balls and table) No score (maybe later, but not now) Probably slow : for example two balls near eachother in a corner

15. Any Questions ? ? Release date: dec 9th 2002 see http://wasp.cs.vu.nl/mma2 for link
