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. Additionally, it could be explained by noticing a certain amount of
detail depending on how close something is, giving a sense of
depth perception
Depth perception is the ability to perceive distance to objects in the world using the visual system and visual perception. It is a major factor in perceiving the world in three dimensions. Depth perception happens primarily due to stereopsis an ...
