Three Point Perspective
Three-Point Perspective is often used in
architectural drawing using lines parallel to the
Cartesian axes x, y, and z. This perspective finds
relevance in drawing buildings.
Isometric Perspective
This refers to a perspective where distant
objects and figures become smaller but the
parallel lines do not converge. What happens to
be that lines that are perpendicular to the plane
become sharp diagonals as drawn thus turning
the squares or rectangles into parallelogram.
Atmospheric Perspective
Atmospheric perspective or aerial perspective
expresses nature in their distance. It simply
stated, objects perceived to often appear as
blurred, misty looking, and in distinctive or
hazy looking to the eye.
As shown in landscape drawings, distant
objects appear in purple or bluish color and
the same is true with respect to the color of
the sky. Color pencil drawings and watercolor
pencil drawings often use this kind of perspective.
