The server may receive capability information from the client, allowing the virtual display driver to resolve differences between the APIs supported on the server and the client. ## Claims ### Claim 1 A server apparatus for providing cross-platform remote access to 3D graphics applications, the server apparatus comprising: memory for storing a server application; a communication interface for receiving a request sent over a communication network from a client device regarding the server application; a processor for executing instructions, wherein execution of the instructions by the processor: initiates the server application in response to the client request, wherein the initiated server application invokes a graphics call to a server 3D library; determines that the graphics call to the server 3D library makes use of only two dimensions; and encodes the graphics call invoked by the initiated server application, wherein the graphics call determined to make use of only two dimensions is converted into a two-dimensional command; and wherein the communication interface transmits the encoded graphics call to the client device via the communication network. ### Claim 2 (depends on 1) The server apparatus of claim 1, wherein memory further stores the server 3D library and wherein the server 3D library comprises graphics functions corresponding to graphics functions in a 3D library at the client device. ### Claim 3 (depends on 1) The server apparatus of claim 1, wherein the communication interface further exchanges capability information regarding the graphics capability with the remote client, the capability information comprising information regarding a 3D library at the client device. ### Claim 4 (depends on 3) The server apparatus of claim 3, further comprising a server virtual display driver configured to receive the capability information and to encode graphics calls for the client device based on the client 3D library in the capability information. ### Claim 5 (depends on 4) The server apparatus of claim 4, wherein the server virtual display driver maintains a central repository of capability information regarding the client device. ### Claim 6 (depends on 4) The server apparatus of claim 4, wherein the server 3D library is configured to query the server virtual display driver to determine capabilities of the client device. ### Claim 7 (depends on 4) The server apparatus of claim 4, wherein the server virtual display driver is configured to distinguish between platform-specific graphics calls and cross-platform graphics calls. ### Claim 8 (depends on 3) The method of claim 3, wherein the processor encodes the graphics call in accordance with the capability information regarding the client 3D library available on the remote client device. ### Claim 9 A method for providing cross-platform remote access to 3D graphics applications, the method comprising: storing a server application in memory;
