Foreground Script 10

Script name

Playing alone

Length

307 frames

Description

In this scene a man is playing on his own with a ball and a racket. Excepting the end of the sequence, the ball never leaves the scenario. However sometimes it is occluded to the camera by the own man, who is continously jumping, spining and running to keep it on the air.

This script is mainly intended to show:

  • Non rigid object (player) interacting with rigid object (ball)
  • Very different object velocities and sizes
  • Oclussions

Involved critical factors

Object textural complexity

Object structure

Uncovered extent

Object size

Largest velocity difference

Complex interactions
