The illusion of three-dimensional drawings lie in the use of isometric
perspective, in which the artist uses parallel lines and congruent
angles to depict geometric objects. The eye tends to introduce
incongruities in perspective, such as the way in that a straight road
appears to narrow as it stretches away from the viewer. Isometric
perspective, however, adheres to the true specifications of the object,
portraying uniformity where the eye would suggest otherwise. The
fantastic illusion of depth in these illustrations can be further
enhanced with the use of color or shading to fool the eye and captivate
the mind. These 31 amazing images can be colored to emphasize their
solidity or shape; they can also be copied, expanded, or used as a
source of graphic and design inspiration. They are a wonderful and
fascinating way for young and old alike to study geometrical perspective
or color creatively.
