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.
