PROBLEM TO BE SOLVED: To provide a shared virtual space display system which can improve its total processing efficiency. SOLUTION: In a synchronous thread 73, a camera clone object 74 is updated by a distributed object mechanism in response to a camera object 72 that is updated in a mouse thread 71. In an avatar control thread, 75, the conversion matrix of a relevant avatar object is changed by referring to the contents of the object 74. A coordinate transformation thread 76 performs the coordinate transformation of polygons by means of the changed conversion matrix, and a visible polygon selection thread 77 selects a polygon to be drawn out of the polygons which has undergone the coordinate transformation. A context generation thread 78 generates the graphics context data from only the polygon to be drawn, and a set-up thread 79 transmits the generated graphics context data to a graphic processing part.
