1. A method comprising:

  • a display server updating a shared visibility structure, wherein the shared visibility structure contains data representing a set of 3D objects;

    an event manager reading at least a subset of the data from the shared visibility structure and processing said at least a subset of the data to determine a first of said 3D objects indicated by a picking shape in response to an input event;

    the event manager sending a message to a client informing said client that a window corresponding to said first object is intersected by the picking shape;

    wherein the display server and the event manager execute in separate processes within an operating system environment such that the process in which the display server executes is distinct from the process in which the event manager executes.
