Talk Title: Feature Based Modeling: A T

ransfinite Interpolation Approach

Talk Abstract:
For purposes of

this presentation features are defined to be
the salient attributes of

an object that characterize its shape.
They include distinguishing curv

es slopes at those curves
ridges corners material or construction b

oundaries and so
forth. In traditional modeling many curves in a mode

l exist
only to satisfy mathematical requirements; they are not featur

We develop a new interpolation approach in which the surface

passes through curves and in which the curves with specified

almost always have a design purpose. We characterize
the method mathem

atically and describe a number of applications
from mechanical engineer

ing to organic shape creation. The tech-
nique allows multisided patchi

ng with G2 continuity disconnected
topology with dangling curves and w

atertight intersections.

Two functional modeling systems based on th

e new method will be
demonstrated; one for conceptual design and the ot

her for terrain.
