Description

This scene is stared by a radio-controlled car and a robot holding a small bottle. The robot moves slowly, in a single direction and stays all the time within the camera field of view. On the contrary, the car moves much quicker, in many directions, getting out the scene several times (yet quickly reappearing again). There are constant oclussions (either from the robot to the car or from the car to the robot) until finally the car runs down the robot. When this happens the robot loses his bottle, which rolls over the floor.

This script is mainly intended to show:

  • Two rigid non-textured objects of very different velocities interacting.
  • Objects dissapering and appearing again into the scene
  • Object oclussions
  • Object splitting

Involved critical factors

Object textural complexity

Object structure

Uncovered extent

Object size

Largest velocity difference
