Ok, then I should give you a bit more of information:

- for a topspin, initial speed of the ball (when it is hit) can be as high as 30 m/s

- longitudinal dimension of the table is 274 cm (two halves of 137 cm)

- the players will be typically 4 to 8 m apart from each other

Please ask if you need some missing information.

The radius for the ball is only 2cm, and the distance between player is 4-8 meter apart.

The ball will become a tiny dot if everything are drawed to their size with the same proportion.

Do you have any suggestion how to show everything on the computer screen at the same time?
