At least one file containing information is transferred across a distributed network environment. The information allows at least one application configured to execute on at least one client workstation to display a portion of a distributed hypermedia document within a browser-controlled window, to respond to text formats to initiate processing specified by the text formats, to identify an embed text format which corresponds to a first location in the distributed hypermedia document and to automatically invoke program code being part of a distributed application located on two or more computers coupled to the distributed hypermedia network, in response to the identifying of the embed text format, in order to enable an end-user to directly interact with an object when the object is displayed within a display area created at the first location within the portion of the distributed hypermedia document being displayed in the browser-controlled window.

Distributed hypermedia method and system for automatically invoking external application providing interaction and display of embedded objects within a hypermedia document

A system allowing a user of a browser program on a computer connected to an open distributed hypermedia system to access and execute an embedded program object. The program object is embedded into a hypermedia document much like data objects. The user may select the program object from the screen. Once selected the program object executes on the user's (client) computer or may execute on a remote server or additional remote computers in a distributed processing arrangement. After launching the program object, the user is able to interact with the object as the invention provides for ongoing interprocess communication between the application object (program) and the browser program. One application of the embedded program object allows a user to view large and complex multi-dimensional objects from within the browser's window. The user can manipulate a control panel to change the viewpoint used to view the image. The invention allows a program to execute on a remote server or other computers to calculate the viewing transformations and send frame data to the client computer thus providing the user of the client computer with interactive features and allowing the user to have access to greater computing power than may be available at the user's client computer.
