Which design technique creates the illusion of size by positioning items on stage?

The design technique that creates the illusion of size by positioning items on stage is forced perspective. This method uses optical illusion to manipulate the viewer's perception of the size and distance of different elements in a scene. By strategically placing objects at varying distances from the viewer and arranging them according to specific angles, the designer can create a convincing 3D effect on a typically flat stage. For instance, an object positioned closer to the audience may appear significantly larger than one that is farther away, even if they are similar in actual size.

The effectiveness of forced perspective relies heavily on how items are scaled and arranged in relation to each other. This technique is commonly used in theatre, film, and photography to enhance storytelling and create more dynamic visuals without the need for elaborate props or stage setups.
