Abstract
An apparatus for determining whether polygons which form objects defined by graphic data generated by CAD intersect with virtually generated light rays. Polygons which are not intersected are removed from the graphic data as unnecessary for the generation of CG data. An apparatus is also described in which path passage points which pass through an animation path within a virtual world are interactively set. If an object exists that interferes with a path that joins adjacent path passage points, an alternate route path which detours around the interfering object is generated. An apparatus is also described in which a path of a moving object is interactively set on a perspective view of the virtual world as viewed from one direction. The position of the set path in the virtual world is calculated, and the position of the path in the direction of viewing is corrected to a position that is removed from an object by a prescribed distance.
