Texture

 ** Texture ** is that specific quality of a surface which results from its three-dimensional structure. Texture is most often used to describe the relativesmoothness or roughness of a surface. It can also be used to describe the characteristic surface qualities of familiar materials, such as the roughnessof stone, the grain of wood, and the weave of a fabric. There are two basic types of structure. tactile texture is real and can be felt by touch; visual texture is seen by the eye. all tactile textures provide visual texture as well. Visual texture, on the other hand, may be illusory or real.  - __Visual textures__: Are the ones perceived by the eyes. May be ilusory or real.

- __Tactile textures:__ These are real, can be felt by touch. All tactile textures also provide visual textures as well.

All materials have some degrees of texture, from plastic to stone, but all textures from a distance appears to be relatively smooth.This is an example of how scale, viewing distance and light can affect the perception of a texture and the surfaces they articulate.

Texture is important in the architecture because it changes the way we see and perceive space. The relative scale of a texture can affect the apparent shape or position of a plane in space. Textures with a directional grane can accentuate a plane’s length or width and also textures can reduce the scale of a plane or increase its visual weight.

In conclusion, textures tend to fill the space in which they exist.
