1. A method of computer generation of an interactive virtual reality world for monitoring and/or controlling a process that is physical or computational, comprising:

  • constructing a first group of one or more related screen displays associated with the operation of an industrial or commercial process, which screen displays, called raw data views, are analog representations or alphanumeric equivalents of outputs from at least two signal interfaces of equipment or of variables in the industrial or commercial process that is to be monitored, controlled, or simulated;

    constructing a second group of one or more related screen displays associated with the operation of an industrial or commercial process, which screen displays, called derived views, include visual representations, called output objects, of one or more processing variables or of one or more units of processing equipment in the industrial or commercial process that is to be monitored, controlled, or simulated, which output objects are derived from outputs from analog or digital signal output, or from analog or digital sensor interfaces of equipment or of variables in the industrial or commercial process that is to be monitored, controlled, or simulated;

    constructing in the derived views one or more visual representations, called input objects, of controllable elements, if any, in the industrial or commercial process that is to be controlled or simulated, which input objects include visual representations of adjustable parameters, called control elements, associated with an analog or digital signal input interface of a controllable element of a unit of equipment or of a computational module in the industrial or commercial process that is to be controlled or simulated;

    interfacing the input objects, including the control elements thereof, with the corresponding inputs of signal interfaces of equipment or of variables in the industrial or commercial process that is to be controlled or simulated so that changing the control elements through manipulation by mouse, keyboard command, or by other input device associated with the computer displaying a derived view, a value or state of a control element in an input object causes a corresponding change in the analog or digital signal presented at the corresponding signal input interface of a unit of equipment or of variables or of a computational module in the industrial or commercial process that is to be controlled or simulated;

    controlling a unit of equipment or of a computational module in the industrial or commercial process through manipulation of the control elements; and

    interfacing through communications circuits or network one or more interactive virtual worlds with a human or cyber user of the one or more interactive virtual worlds.
