Projection
n.
The representation of something; delineation; plan;
especially, the representation of any object on a perspective plane, or
such a delineation as would result were the chief points of the object
thrown forward upon the plane, each in the direction of a line drawn
through it from a given point of sight, or central point; as, the
projection of a sphere. The several kinds of projection differ
according to the assumed point of sight and plane of projection in
each.
