Texture refers to the surface quality or "feel" of an object, whether smooth, rough, soft, etc. There are two main types of texture - tactile texture which is actual texture felt through touch, and visual texture which is implied texture perceived through sight alone. Tactile texture is created by adding, subtracting, or engraving material, while visual texture represents tactile texture using graphic elements to imply a texture. Natural textures belong to natural surfaces like skin or bark, while artificial textures are man-made surfaces like steel or paper. Texture, whether tactile or visual, can be used in art creation through techniques like lines, patterns, folding, or dripping.
