System for selectively performing parallel or sequential drawing processing

A distributed drawing processing system which includes a drawing server for integratedly executing a string of drawing commands transmitted from a client program for graphics display. In the system, the client program divides the drawing command string into a drawing command block of a string of drawing commands processable on a parallel basis and a drawing command block of a string of drawing commands not processable on the parallel basis, and transmits the divided drawing command string blocks to the drawing server. The drawing server executes the drawing command string while judging whether to process it on the parallel or sequential basis with respect to each of the divided drawing command string blocks.
