Because of the advances of computer hardware and software, Computer Aided Instruction (CAI) makes learning effective and interesting through the use of interactive multimedia technology. Recently, Augmented Reality (AR) technology has begun to surge as a new CAI tool because of its ability to create tangible and highly interactive user interface. In(More)
The support of Boolean set operations in free-form solid modeling systems requires the repeated intersection of parametric surfaces. Present approaches to this problem are sequential and must make trade-offs between accuracy, robustness and efficiency. In this paper, we investigate a parallel approach to the surface intersection problem that shows, both(More)
