Abstract
The present invention provides a three-dimensional perspective, virtual workspace to window based display systems. The user may activate control buttons to transform a typical two-dimensional window to a three-dimensional perspective, virtual workspace. The transformation to the three-dimensional workspace provides a perspective or sense of depth to the display of the windows containing computer applications. In this manner, a simulated three-dimensional window display environment for the operating system is provided. The operating system utilized in connection with the present invention receives data for storage in a destination rectangle in a frame buffer. The data designated for storage in a destination rectangle is generally given in pixel coordinates. The operating system scales the data's dimensions to the provide a three-dimensional perspective appearance on the display screen. When a user indicates that a window should be displayed in a particular perspective or size, coordinates representing the window and data contained therein are multiplied by a transformation matrix to yield the specified perspective or size.
