A Web 3D image display system capable of smoothly displaying a 3D image on the Web browser. A computer system in which a 3D image file is downloaded from a server and a 3D image is displayed on the Web browser. The computer system includes a server holding a 3D compressed file which has been edited and generated according to 3D scene information from a VRML file or the like and a 3D applet for displaying a 3D scene and a Web browser for displaying a 3D scene. By the Web browser, a 3D applet is requested to the server and downloaded. The 3D applet is executed and the 3D compressed file is requested. After the file is downloaded and all the information is received, the Web browser alone executes the 3D applet, real time 3D rendering, and motion algorithm, and displays a continuously interactive 3D scene.
