the use of Shapes in visual design - Archetypal Forms
Because
light projects in straight lines it tends to react in a harsh way
with objects that have sharp edges, like a cube or pyramid it tends
to either light the surface or not.
Dramatic visual effects can
be created where one surface is in full light while the other surfaces
are in deep shadow.
In terms of light, we might consider there
are three effects that a flat plane or surface on one of these
forms can have.
Fully lit,
no light,
oblique lighting where the light is just catching
across the surface of the form.
also another factor which can come into play
and is related to the surface of the material itself, is reflection.
