Foreground Script 2

Script name

Exhausted runner

Length

367 frames

Description

The scene begins with a visibly tired runner struggling to advance. Exhausted, he starts eating an apple, but after the first bite he changes its mind and throws it with a parabolic trajectory. The apple consecutively leaves and joins the scene finally reaching the ground. In that moment a second runner turns up and, in a few steps, overtakes the first one. Then she looks back like reproaching the first runner for being so slow while shaking a stick. After that she keeps on running until leaving the screen.

This script is mainly intended to show:

  • Textured and non textured, rigid and non rigid objects interacting
  • Object oclussions and splittings
  • Objects with significantly different velocities and sizes
  • Objects dissapearing and appearing again into the scene

Involved critical factors

Object textural complexity
