It is an object of the present invention to provide special effects which will make a video game more realistic.When a virtual light source exists in a three-dimensional virtual space, if a light from the light source extends toward a camera, a flare is generated on a screen because of incidence of the ray of light into a camera lens, thereby forming a dazzling picture in accordance with the state of backlight.

1. A method of displaying picture data in a three-dimensional virtual space, comprising:forming a set of picture data based at least upon a complete object for storage in a database, wherein the forming further comprises:locating all objects composed of a set of polygons in a three-dimensional virtual space;setting a plurality of visual points in the three-dimensional virtual space;forming for each visual point a projected picture by the set of polygons, within a display region as seen from each visual point, being projected on a plane of projection;identifying whether each of the set of polygons is visible or invisible from each visual point according to the projected picture formed on the plane of projection;forming a set of object data showing whether each polygon is visible or invisible from each visual point based on said identification, and on a common or similar characteristic of the polygons;forming a plurality of sets of object data by making same or similar patterns into a group based on a data pattern of each polygon, the data pattern representing whether the polygon is visible or invisible from each visual point;forming an object table of flags representing only object data that is visible from each visual point;storing the formed object table in the database as a completely formed set of picture data; anddisplaying the formed set of picture data. 2.
