Answer to Question 2
Relative sizethe largerappearing of two objects that are thought to be the same size is perceived to be closer. Interposition involves one object blocking or obscuring our view of another object. The object that obscures another object is thought to be closer to us than the object that is obscured. Relative clarity involves perceiving more distant objects as less clear because of the effects of atmospheric phenomenon, such as dust, smoke, or water droplets in the air. Thus, objects that are seen more clearly are seen as relatively closer than those objects seen as less clear. Texture gradient can also serve as a distance cue, with smoother, less-detailed textures indicating greater distance and coarser, more-detailed textures indicating closeness to the observer. Linear perspective is the perception of the convergence of parallel lines in the distance. Objects and the distance between them appears to be smaller with greater distance from the observer. Shadowing involves our perception of patterns of
light and dark. These patterns can create the appearance of three-dimensional objects or of curved surfaces. We perceive objects that are lighter on top and darker on bottom to be bumps, and objects that are darker on top and lighter on bottom appear
to be depressions.
