PERSPECTIVE
DRAWING 8
The
Perspective of a Circle
A
circle in perspective is called an ellipse. The drawing
of ellipses is controlled by rectangular perspective.
Our
drawing above of an ellipse illustrates this technique.
There are two distinct stages in its creation:
fig.1
The circle is first visualised in plan form on a flat square
grid . Each
section of the grid contains one quarter of the circle.
fig.2
The square grid is distorted according to the laws of perspective.
The circle is then redrawn onto the distorted grid to create
an ellipse.
The
diagonals of the grid have been drawn on both illustrations
to help with the plotting of the circle and ellipse.
