A method of viewing an object by imparting a continuous, steady, cyclic motion to the object which keeps the orientation of the object substantially the same. The object can be a real 3-D object or can be an abstract object such as those used in 3-D computer graphics. Real objects viewed in an apparatus which includes a support, a viewpoint, and a mechanism for imparting a relative wobble between the support and the viewpoint to create a wobbling image of the object. In one embodiment, the support is caused to wobble and the viewpoint is substantially stationary, and in another embodiment the support is substantially stationary and the image at the viewpoint is caused to wobble. A computer implemented process for viewing the object includes the steps of developing, within a computer system, a description of a 3-D object, specifying a wobble procedure, and displaying an animated representation of the object on a visual display as determined by the wobble procedure.

A computer program product for displaying a series of two-dimensional representations of a three-dimensional object to a viewer to provide said viewer with a three-dimensional image of said object, said computer program product comprising a computer usable medium having embodied therein the following elements: a) computer readable program code devices configured to cause a computer to define a coordinate system including three mutually orthogonal unit vectors, e1, e2, and e3; b) computer readable program code devices configured to cause a computer to define a set of coordinates corresponding to a base orientation of said three-dimensional object; c) computer readable program code devices configured to cause a computer to transform repeatedly said coordinates by applying to said coordinates a rotational wobble function W(s, t), said application of said rotational wobble function W(s, t) including: i) rotating said unit vector e1 by s radians about said unit vector e3 to produce a vector V; and ii) rotating said coordinates about said vector V by t radians to obtain thereby a transformed set of coordinates corresponding to a transformed base orientation of said three-dimensional object; d) to generate thereby a series of transformed coordinate sets corresponding to a series of transformed base orientations of said three-dimensional object; and e) computer readable program code devices configured to cause a computer to display said series of transformed coordinate sets as a smooth repetitive motion of two-dimensional representations of said transformed base orientations of said object wherein said object maintains a substantially constant orientation such that the total display of said two-dimensional representations provides said viewer a three-dimensional image of said three-dimensional object, wherein said sequential display does not include said coordinates corresponding to said base orientation.
