Abstract
A system for large scale spatial positioning of a 3D virtual object in a 3D virtual scene, includes a computing device. The computing device: displays a guide plane attached to the object, the guide plane passing through a center of the object and being translucent, the guide plane indicating lines and curves of intersection between the guide plane and other objects of the scene. When moving the object along an axis, the computing device determines a normal of the guide plane to be parallel to the axis and passing through the center of the object, and moves the guide plane with the movement of the object. When moving the object across the movement plane, the computing device determines a normal of the guide plane to be parallel to a normal of the movement plane, and holds the guide plane static.
