Parallel processing of calculation processor and display processor for forming moving computer graphic image in a real-time manner

An apparatus which forms and displays a moving image in a real-time manner on a display, comprising:

• a moving image calculation processor which sequentially calculates and forms moving image data in 3-dimensional virtual space in real time;
• a memory apparatus which stores 3-dimensional moving image data;
• a calculation result accumulator which accumulates the 3-dimensional moving image data formed by said moving image calculation processor into the memory apparatus;
• a display processor which converts the 3-dimensional moving image data read out from said memory apparatus into 2-dimensional moving image data to realize a predetermined viewpoint for moving image display;
• a controller which controls said moving image calculation processor to continuously and sequentially calculate the 3-dimensional moving image data for a plurality of points in time ending at successive predetermined time intervals (Td), and which controls said display processor to sequentially read out and convert the 3-dimensional moving image data from said memory apparatus into 2-dimensional moving image data at said predetermined time intervals (Td) and in real time, wherein said controller continuously displays a current 2-dimensional moving image data of said sequentially converted 2-dimensional moving image data until calculation of a next 2-dimensional moving image data is finished by said display processor and forcibly stops conversion of a current 3-dimensional moving image data by said display processor and initiates conversion of a next 3-dimensional moving image data if conversion extends beyond a predetermined period of time;
• and
• a graphics accelerator which converts the 2-dimensional moving image data read out from the controller into pixel data and outputs the pixel data to the display.
