Foreground Script 9

Script name

Playing tennis

Length

1378 frames

Description

In this scene, two people join the scene and start playing ping-pong. During the game the ball falls to the floor several times, sometimes even disappearing from the scene. In one of these occasions it is changed by another one with a different colour.

This script is mainly intended to show:

  • Non rigid objects (players) interacting with rigid objects (ball)
  • Very different object velocities and sizes
  • Objects dissapering and appearing again into the scene
  • Temporary merge (especially when the ball is picked up from the floor) and split

Involved critical factors

Object textural complexity

Uncovered extent
