Description

The initial scenario of this scene is made up of an empty chair and a newspaper lying on the floor. Then, a man “A” joins the scene, picks up the newspaper and sits down on the chair to read it. He starts doing a lot of gestures and expresive movements when reading something. In that moment, a second man “B” appears into the scene, snatches the paper out of the first man’s hands, throws it to the floor and goes on his way until leaving the scene. Then, “A” stands up shouting and cursing at “B”, but after a while he has to run away, followed by A.

This script is mainly intended to show:

  • Textured and non textured non rigid objects interacting
  • Moving objects remaining almost static (man reading newspaper only making some gestures) and quickly changing their pose
  • Object merging and splitting
  • Objects moving at different velicities (The "B" man velocity when the A man is reading, the newspaper velocity when it is thrown to the ground)
  • Objects dissapearing and appearing again into the scene

Involved critical factors

Object textural complexity

Object structure

Uncovered extent
