Displacement Mapping

Displacement mapping is a computer graphics technique that adds realistic surface detail to 3D models by physically altering their geometry based on a texture or pattern. Unlike bump mapping, which only creates the illusion of depth, displacement mapping actually modifies the surface, making features like wrinkles or pores stand out physically. It analyzes a map image that contains height information and adjusts the model's shape accordingly, resulting in more accurate and detailed surfaces that respond better to lighting and perspective. This technique is commonly used in high-quality rendering to enhance realism in visual effects, film, and gaming.
