Mr. Steve Williams a graduate student of this
department will speak on ``Draw Packages: A Survey and
a Proposed Multitasking Implementation''.
TIME: 2:00 PM
ROOM: MC 6082
ABSTRACT
A draw package is a computer program that allows a user
to create accurate drawings in a structured format.
This essay defines what a draw package is and how one
differs from programs such as paint systems and
Computer Aided Design systems. The differences between
two dimensional and three dimensional draw packages are
also explained.
A number of selected packages are introduced which,
through various techniques, have increased the ability
of a user to construct constrained drawings. This
survey outlines a representative collection of draw
packages. As well, current trends in improving draw
systems are listed.
The proposed and partially completed multitasking
implementation of an interactive two dimensional draw
package is described. The design is capable of
producing high quality images in a format suitable for
display on many output devices. The implementation is
part of the Adagio workstation.
