Final answer:
To create vanishing points in their artwork, artists use linear perspective, which employs converging parallel lines to simulate depth. Atmospheric perspective is used to render objects less distinct as they recede into the distance, mimicking the natural haze of the atmosphere. Option number a is correct.
Step-by-step explanation:
Artists create one or more vanishing points in their artwork using linear perspective, which involves drawing a set of parallel lines that appear to converge as they recede toward the horizon.
This technique enables the creation of an illusion of three-dimensional space on a two-dimensional surface. One-point linear perspective is simplest, utilizing a single vanishing point, while two-point and three-point perspectives use two and three vanishing points respectively.
Atmospheric perspective is another method used by artists, particularly in landscape painting, to convey depth. The technique is based on the observation that distant objects appear smaller, grayer, and less distinct because of the scattering of light by particles in the air. As objects recede in space, artists represent them with decreasing contrast, lighter and grayer tones, and reduced detail to mimic this effect.
In summary, while linear perspective relies on geometric lines and vanishing points to create depth, atmospheric perspective uses gradations in color and clarity to suggest distance.
