Claim One:
1. A laptop computer system, comprising: a base that includes an input means for inputting data; a display device pivotably connected to the base; a host processor; a sensor coupled to the display device and to the host processor, wherein the sensor is configured to detect a first orientation of the display device; a memory storing driver software configured to: receive input information that comprises two-dimensional (2D) image content from the host processor, associate the 2D image content with one or more three-dimensional (3D) polygons having vertex data, and specify a first transform to be applied to the one or more polygons, wherein the first transform is based at least partially on the first orientation of the display device; and a 3D graphics subsystem configured to receive the 2D image content and the vertex data, the 3D graphics subsystem comprising: a geometry processor configured to receive the vertex data, wherein the vertex data includes a first location for a first vertex of a polygon and a first location for a second vertex for the polygon, a transform engine residing within the geometry processor and configured to produce a rotated second location for the first vertex and a rotated second location for the second vertex using the first transform, a graphics memory, a memory interface coupled to the graphics memory and configured to: store the 2D image content as texture data in the graphics memory, and store 3D rotated image data comprising one or more rotated polygons in the graphics memory, and a texture processor configured to apply the texture data to the first vertex at the rotated second location and the second vertex at the rotated second location to produce primitives comprising the 3D rotated image data.
