Lesson details

Key learning points

  1. Forced perspective can be achieved with scaling
  2. Animators use coordinate geometry to animate images

Keywords

  • Forced perspective - Forced perspective is a technique that makes an object appear larger, smaller, farther or closer than it really is.

Common misconception

Pupils may struggle in the first learning cycle with where each object should be placed.

The closer to the observation point an object is, the larger it appears to be. So if we want an object to appear larger than something else, we need to place it closer to the camera.

There are some excellent TED-Ed talks by Pixar which go into maths in animation in more detail. Consider watching these with your pupils if they are interested in this type of career.
