A view that displays a parallel projection along one of the major axes In an orthogonal view, the camera is oriented so it is perpendicular (orthogonal) to specific planes: the Top view faces the XZ plane, the Front view faces the XY plane, and the Right view faces the YZ plane An orthogonal view eliminates the effect of distance from a viewpoint, which provides a useful means of locating points and objects in 3D space and is particularly helpful when modeling objects in wireframe mode An orthogonal view is in contrast to a perspective view See also Perspective
Right-angled; rectangular; as, an orthogonal intersection of one curve with another
