Spatial Disposition of Axes in a Generalized Cylinder Representation of Objects That Do Not Encompass the Viewer,

Abstract

It is proposed that the 3-D representation of an object is represented primarily by a stick-figure configuration, where each stick represents one or more axes in the object's generalized cylinder representation. The loosely hierarchical description of a stick figure is interpreted by a special-purpose processor, able to maintain two vector and the gravitational vertical relative to a Cartesian space-frame. It delivers information about the appearance of these vectors.
