orthogonal projection
orthogonal projectionn. The two-dimensional graphic representation of an object formed by the perpendicular intersections of lines drawn from points on the object to a plane of projection. Also called orthographic projection.orthogonal projection n (General Engineering) engineering the method used in engineering drawing of projecting views of the object being described, such as plan, elevation, side view, etc, at right angles to each other
Orthogonal Projection
orthogonal projection[ȯr′thäg·ən·əl prə′jek·shən] Also known as orthographic projection. (graphic arts) A two-dimensional representation formed by perpendicular intersections of lines drawn from points on the object being pictured to a plane of projection. (mathematics) A continuous linear map P of a Hilbert space H onto a subspace M such that if h is any vector in H,h= P h+w, wherewis in the orthogonal complement of M. A mapping of a configuration into a line or plane that associates to any point of the configuration the intersection with the line or plane of the line passing through the point and perpendicular to the line or plane. Orthogonal Projection a particular case of parallel projection in which the axis or plane of projection is perpendicular (orthogonal) to the direction of projection. |
