Abstract
PURPOSE:To speed up display of a three-dimensional picture by means of a hidden line elimination processing by transmitting a write control signal from a specified Z buffer access control means to a frame buffer access control means which is intervened between a drawing processor and a frame buffer. CONSTITUTION:In a three-dimensional picture display device G displaying picture information from dot data corresponding to respective picture elements in a monitor 11, the frame buffer access control means 6 is provided between the drawing processor 3 and the frame buffer 7, and the Z buffer access control means 8 between the processor 3 and a Z buffer 9. The depth value of first dot data which is previously displayed in the monitor 11 is stored in the buffer 9, and the means 8 compares the depth value and that of second dot data from the processor 3. If second dot data is in front of a gazing direction, the depth value in the buffer 9 is updated and the write control signal is transmitted to the means 6.
