Texture – Texture describes the visual or tactile quality of a figure or object. Texture can be created visually through the use of multiple marks of sufficient similarity so as not to be initially perceived as individual figures. Texture can be created physically through surface variation or the inherent properties of a material, such as sand as opposed to porcelain.
Discontinuity in Texture
In this example, the square in the center becomes the primary figure within the sequence because of motion. The motion is a change of texture. The overall brightness and hue of the squares remains constant but the texture changes over time. If you stop the movie at the beginning or end, there is no clear primary figure due to all three squares being fundamentally identical, with slight texture variations.
