Texture gradient is the distortion in size which closer objects have compared to objects farther away. It also involves groups of objects appearing denser as they move farther away. Also could be explained by noticing a certain amount of detail depending on how close something is, giving a sense of depth perception. There are three main forms of texture gradient: density, perspective, and distortion of texture elements.
