Foreground Script 3

Script name

Dangerous race

Length

258 frames

Description

Three significantly fast runners (A, B, C) struggle to overtake each other. Runner A comes first into the scene. After a while, runner B turns up running quicker than A but when he is about to overtake him, C prevents him from doing it, throwing furiosly an object to them, holding back to B (dragging him out of the scene), passing A and being the first in leaving the scene. He is followed but A and B.

This script is mainly intended to show:

  • Textured and non textured, rigid and non rigid objects interacting
  • Constant object occlusions
  • Objects with different velocities, some of them being irregular
  • Objects dissapearing and appearing again into the scene

Involved critical factors

Object textural complexity

Object structure

Uncovered extent

Object size

Largest velocity difference

Complex interactions
