ABSTRACT:
A method and apparatus for generating images wherein access to a main memory is minimized during a translation of an image of a 3D object or the like on a display screen to increase the speed of the translation process. A string of draw commands for drawing an image is preceded by an offset draw command which indicates offset values for the coordinates of the vertices of the image, and the image is translated on the display screen in accordance with the offset draw command. A header portion of each of the offset draw command and the draw commands that constitute the draw command string includes data indicating the address on the main memory of the next draw command to be executed. The image generation apparatus includes a frame buffer in which an image is drawn, a CPU for generating a string of draw commands to draw the image and an offset draw command indicating offset values for the coordinates of the vertices of the image, a main memory for storing the string of draw commands and offset draw command generated by the CPU, and a drawing device portion for executing the string of draw commands and offset draw command from the main memory to draw a translated image on the frame buffer.
