Abstract

A simulation procedure founded on SGI Onxy4 visualization system and SGI OpenGL Performer™ visualization development toolkit was discussed; a scene graph in accordance with its node configuration motion and man-machine interaction simulation were designed; based on OpenGL Performer, a transforming algorithm for scene graph object moving simulation was studied; the interaction rules between scene objects, the event triggering and feedback method of the simulation procedure was discussed and designed; and finally, separately took examples by a virtual man interaction module, a numerical lathing-milling machining center and a mud-water balanced tunnel boring machine, three operation instances for moving simulation and interaction were programmed and realized.
