Abstract:
1. A computer-implemented method for checking for persistence of a connection between object space and surface space for an application making use of a 3D graphics application programming interface (API), comprising: the computer executing the application and implementing the 3D graphics API as a layer between said executing application and a graphics pipeline that renders and processes graphics data; the computer using the 3D graphics API to perform a check for the persistence of the connection between object space and surface space at a time substantially when a recurring function call is made, wherein the recurring function call is a cyclical function call; and the computer spoofing one or more other checks for the persistence of the connection between the object space and the surface space that occur at times other than when the recurring function call is made, thereby avoiding a computation associated with the one or more other checks.
