A method of initializing application instructions on a processing system. An application () comprises a number of dynamically shared objects or modules. Each of these modules may include data structures () that require initialization. Modules are dependent upon each other, and a module initialization order is identified by automatically registering a module's dependencies in an initialization list () during module loading, processing module dependencies to identify all dependencies, and generating an initialization schedule (). Module initialization () is then performed. Plug-in modules can be loaded and initialized after the application has started, and the plug-in schedule is appended to the initialization schedule. Finalization is performed in reverse order, when the application is closed.

Data processing apparatus generates initialization schedule by sorting module order according to number of its dependencies for initializing data affecting execution of operational instructions

In a virtual set a computer generated virtual image is combined with a real set. Registration data defines a transformation allowing virtual image data to be combined with image data derived from a real set. A reference plane is identified ( ) in the real set which is associated ( ) to a plane defined in the virtual world space. Differences in positions between the real and virtual planes are determined ( ) to produce registration data.
