Three-dimensional object rotating method, and corresponding computer system thereof

The invention relates to a three-dimensional object rotating method and a corresponding computer system thereof. The three-dimensional object rotating method can be used on a desktop of an operating system and comprises the following steps that: firstly, a three-dimensional driver receives three-dimensional data and rotation information; the three-dimensional data describe a three-dimensional object, and the three-dimensional data come from an application executing the desktop; and then the three-dimensional driver uses a three-dimensional accelerator to describe the three-dimensional object in a virtual shadow picture working-storage section, and carries out rotation processing of the three-dimensional object according to the rotation information. The method, the system and the recording medium can make the rotating and displaying process of the three-dimensional object simpler so as to improve the efficiency of rotating and displaying the three-dimensional object.
