This paper proposes an advanced cut-and-paste editing for three-dimensional models. We introduce a new param-eterization technique based on constrained B-spline sur-face/volume fitting. Our cut-and-paste editing is performed on this parameterization. In our method, a parametric volume is generated so that its isoparametric surface fits to the base surface(More)
—Education of design engineering has started to change in response to the advancement of computer technology. This paper proposes a new design engineering educational framework using an e-learning system called ShareFast, a Semantic Web-based software for document management system with workflow. The software offers a function to keep tracks of learner's(More)
Intrapericardial paraganglioma remains a surgical challenge because of its hypervascular nature and firm adhesion to adjacent mediastinal structures. Here, we describe a 63-year-old female with a giant nonfunctioning intrapericardial paraganglioma tightly adhered to the left atrium. Marginal but complete resection of the tumor was achieved via right(More)
