SHADE & SHADOWS
• The shadow cast b a solid is bound by the
y
shadows of the shade lin of t heobject. It is
es
usually best to beginby determining t he
shadows of significant points in t heform, such
as the end point s of straight lines and the
t angent points of curves.

• Note that shadows of parallel lines are parallel
when t hey fall onthe same planeor on parallel
planes.
• The orthographic projection of a straigh line
t
perpendicular t othe plane of projection is a
point. The shadow of t heline will appear to be
straigh regardless of theshapeof the surface
t
receiving theshadow.
In clarifying therelative depth of projections,
overhangs, and recesses within t hemassing of a
building, shade and shadows can also model the
relief and texture of surfaces.
• Most often simply use a flat or slightly
textured field of gray to indicate shade and
shadows.
• An alternate method is to int ensify the texture
or pattern of amaterial so that we do not lose
a sense of the material that is inshade or
receiving t he shadow.
