How Forced Perspective Creates 3D on a Flat (and Curved) Screen
The effect is an engineered optical illusion built on a 400-year-old principle: anamorphosis. The render is distorted so it only resolves into correct perspective from one viewing angle — the sweet-spot.
The breakthrough is the 90° convex corner wrap: two flat LED panels joined at a right angle, outer corner facing the audience. Render through a virtual camera frustum that matches that exact geometry and the brain reads both planes as one 3D space — objects appear to leap out into the street.
