Abstract

An important characteristic of virtual assembly is interaction. Traditional direct manipulation in virtual assembly relies on dynamic collision detection, which is very time-consuming and even impossible in desktop virtual assembly environment. Feature-matching is a critical process in harmonious virtual assembly, and is the premise of assembly constraint sensing. This paper puts forward an active object-based feature-matching perception mechanism and a feature-matching interactive computing process, both of which make the direct manipulation in virtual assembly break away from collision detection. They also help to enhance virtual environment understandability of user intention and promote interaction performance. Experimental results show that this perception mechanism can ensure that users achieve real-time direct manipulation in desktop virtual environment.
