Abstract

A computer-implemented method may be used to generate a 3D interactive presentation, referred to as a rotograph, illustrating a main object from a rotating viewpoint. A plurality of two-dimensional images may be received. A three-dimensional scene may be generated, with a virtual camera and an axis of rotation. Each of the two-dimensional images may be positioned in the three dimensional scene such that the plurality of two-dimensional images are oriented at different orientations about the axis of rotation. A motion pathway may be defined within the three-dimensional scene, by which the virtual camera is rotatable about the axis of rotation to view the plurality of two-dimensional images in sequence. A plurality of rotograph images may be captured with the virtual camera during motion of the virtual camera along the motion pathway to generate the rotograph, which may be displayed on a display screen.
