Lesson Details

Key learning points

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

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.
