  • Publication number: 20060284867
    Abstract: A screen image for operating a modeling application in a web application server device is displayed in a browser window of a web client device. When an operator inputs an operation related to a three-dimensional model whose CG should be displayed in the screen, the web application server device transmits a drawing command to draw CG of the three-dimensional model to the web client device. The web client device draws CG of the three-dimensional model according to the drawing command through the use of its own graphic accelerator. The invention allows the high-speed drawing of CG of a three-dimensional model on the web client device even when the web application server device provides a modeling service to the web client device.
