Rhombus and Cube
★Exhibit Content: Visual illusion, light and shadow 3D illusion science visual experience ★Interaction: Static wall visual observation interaction ★Operation: 1. Stand in the designated observation area at a distance and look at the panel to distinguish whether the pattern appears as a cube or a rhombus; 2. Move closer to the panel and observe again, comparing the visual differences of the pattern from far and near perspectives. ★Exhibit Description: "Rhombus and Cube" is a wall-mounted interactive exhibit for science popularization of visual illusions and light-shadow perspective, belonging to the optometry exhibition area, and is a recommended exhibit by the PopsciCat Exhibit Store. The exhibit uses a circular gradient background 3D panel, printed with a rhombus flat pattern with light-dark gradient, and the whole is made into a 3D relief shape fixed on the science wall. When viewers observe from a distance, the light and shadow of the pattern form a perspective illusion, visually mistaken for stacked 3D cubes; when viewed up close, the pattern can be seen as essentially a flat rhombus. Through the contrast of far and near perspectives, it intuitively explains how light and shadow deceive the human eye, popularizing the visual illusion principle that seeing is not necessarily believing. ★Scientific Principle: The human eye relies on the light and dark, shadows, and perspective relationships of objects to judge their 3D form. This exhibit is composed only of flat rhombus patterns, and by artificially adjusting the light and dark shades of color blocks, it simulates the light and shadow effects of a cube under light and backlight. When observed from a distance, the brain automatically reconstructs the 3D structure based on shadow information, creating a cube visual illusion; when observed up close, the human eye can distinguish the flat boundaries of the pattern, breaking the 3D illusion and clearly recognizing the basic rhombus shape, intuitively demonstrating the interference of light and shadow on visual judgment.
