## projectionA projection is a transformation in which the image
figure is obtained from the original figure (plane or three-dimensional)
by drawing from the point of the original figure straight lines, which are
either parallel (parallel projection), or concurrent (central
projection), and which intersect the image plane.
The points of intersection of the straight lines (rays of projection) with
the image plane are the image points, the totality of which
yields the image figure. The figure is said to be projected onto the image
plane. See also projective geometry. ## Related category• GEOMETRY | |||||
