Surface texture refers to the feel, appearance, and consistency of a surface. It can be smooth, rough, bumpy, or glossy, and is determined by the material's properties and how it has been processed. Surface texture plays a crucial role in various fields, including art, design, and manufacturing, as it affects both aesthetics and functionality. In nature, surface texture can be observed in different materials, such as the bark of a tree or the smoothness of a pebble. In technology, 3D printing and texturing in computer graphics utilize surface texture to create realistic models and images. Understanding surface texture helps in selecting materials for specific applications.
