 WIRE FRAME is faster to graph and may be more convenient when you’re 
experimenting with different shapes.
Later sections in this module describe CONTOUR LEVELS, WIRE AND COUNTOUR, 
and implicit plots.

The eye angles used to view a graph (
eye
q, 
eye
f, and 
eye
ψ
 Window variables) can result 
in optical illusions that cause you to lose perspective on a graph. Typically, most optical 
illusions occur when the eye angles are in a negative quadrant of the coordinate system.

WIRE FRAME — Shows the 3D shape 
as a transparent wire frame.
HIDDEN SURFACES — Uses shading 
to differentiate the two sides of the 3D 
shape.
