Simultaneous Bidirectional Geometric Model Synchronization between CAD and VR Applications

Most of the research in the field of CAD – VR integration targets the use of VR as a post-processing tool and relatively fewer attempts are aiming at returning feedback from VR back to CAD. In this paper we propose a method allowing the modification of CAD models in a virtual environment with (bidirectional) synchronization of the model description between the CAD and VR applications as the changes are made. A sample implementation of the method is also described and some examples of specific test cases used to confirm the applicability of the method are given.
