DEPARTMENT OF COMPUTER SCIENCE UNIVERSITY OF WATERLOO SEMINAR ACTIVITIES MASTER'S ESSAY PRESENTATION -Monday, May 1, 1989 Mr. Ron Pfeifle, graduate student, Dept. of Computer Science, University of Waterloo, will speak on "n-Dimensional Tensor Product Slices." TIME: 10:30 ROOM: DC 1302 ABSTRACT Tensor product surfaces are widely used in computer graphics and computer aided geometric design for representing freeform curves and surfaces. One feature of standard tensor product surfaces is that surface patches retain vestiges of the original rectilinear shape of the domain of the tensor product. This feature not always desired or necessary. In this talk, we introduce a variant on the tensor product, called the tensor product slice, which can be ------ ------- ------ used to create surface patches of non-rectilinear shape. We will see how this variant retains many of the desirable properties of general tensor products, and show that many properties specific to one type of tensor product, the B'zier tensor product, are also retained by B'zier tensor product slices.
