Convert spherical projection into a cylindrical projection. By which more complex objects can be constructed: a. Quadric surfaces: b. In the figure below, two perpendicular planes are established to form the image planes for a multiview orthographic projection. If the length of the line segment connecting two projected points on the plane is proportional to the geodesic (shortest surface) distance between the two unprojected points on the globe, then we say that distance has been preserved between those two points. In this, all the parallel lines in the object which is not parallel to view plane are converged and the point of converging is known as the vanishing point or converging point. In oblique projection, the projector lines form oblique angles (non-right angles) with the projection plane. A jacquard band featuring the 'Christian Dior' signature embellishes the back.
