Occlusion Ambiguity
Spatial paradox: when Object A is both in front of and behind Object B.
🧐 What do you see?▼
A horizontal bar moves past vertical pillars.High Intensity: The bar appears to passbehind the middle pillar butin front of the side pillars—a geometry that shouldn't exist!
🧠 Why this works▼
This is an Impossible Figure derivative. Our brain prefers to see objects as solid and continuous. When we useLocal Occlusion Cues (like Z-indexing changes) that contradict each other, the brain struggles to build a coherent 3D model.
🧪 Try variations▼
Lower the Intensity. The illusion resets to normal 3D logic, letting you see the difference between "possible" and "impossible" depth layering.
