Abstract
Texture sharing in a graphics memory is disclosed. A primary application establishes a virtual device for interaction with a graphics module. The virtual device includes a texture reference that refers to a render target texture in a graphics memory of the graphics module, and multiple render states, the render states having corresponding render state values. The plurality of render state values is saved in a memory in association with the corresponding render states. An external application module is invoked and provided a virtual device reference to the virtual device. Upon a return of the external application module, the plurality of render states are restored to the corresponding render state values. The graphics module is directed to generate a final scene in a final scene buffer in the memory in the graphics module using the render target texture.
