pseudotexture

Pseudotexture is a term used in computer graphics and image processing to describe a technique that simulates the appearance of real-world textures without relying on actual photographic data or complex procedural generation. It achieves this by using simpler graphical elements to create the illusion of texture. This can involve repeating patterns, color gradients, dithering, or stylized noise. The goal is to evoke a specific visual feel, such as the roughness of stone, the softness of fabric, or the shine of metal, using less computational overhead than photorealistic textures.

The application of pseudotexture is particularly common in video games, especially those with stylized art directions or limited hardware resources. It allows developers to create visually rich environments and objects that are less demanding to render. By carefully designing these simplified textures, artists can achieve a distinct aesthetic that contributes to the overall game's atmosphere and identity. Beyond gaming, pseudotexture can be found in user interface design, motion graphics, and other areas where an impression of texture is desired without the need for high fidelity. The effectiveness of pseudotexture lies in its ability to convey visual information and depth through approximation rather than exact replication.
