Abstract: A computer-implemented method of and system for converting a two-dimensional drawing into a navigable three-dimensional computer graphics representation of a scene that includes inputting the two-dimensional drawing, embedding some portion of the two-dimensional drawings onto one or more two-dimensional planes, arranging the two-dimensional planes in a virtual three-dimensional space; and outputting the arranged two-dimensional planes into the three-dimensional computer graphics representation of the scene.

Abstract: A computer-implemented method of manipulating some portion of a 3D representation of a scene from a reference view direction using a touch-sensitive display unit that includes identifying, by the touch-sensitive display unit, the portion of the 3D representation of the scene to be translated; generating and displaying on some portion of a display device of the touch-sensitive display unit a second 3D representation of the scene from an auxiliary view direction that may be selectively adjustable; and using the second 3D representation of the scene to translate the portion of the 3D representation of the scene.

Abstract: A computer-implemented method and system for generating on a second canvas within a three-dimensional space a three-dimensional representation of an object disposed on a plane of a first, working canvas without leaving the plane of the first, working canvas, the method including designating an axis of rotation on the plane of the first, working canvas, e.g., a hinge function; and rotating the object about the axis of rotation, i.e., the hinge function, without the object leaving the plane of the first, working canvas.
