DEPARTMENT OF COMPUTER SCIENCE UNIVERSITY OF WATERLOO SEMINAR ACTIVITIES COMPUTER GRAPHICS SEMINAR - Friday, June 26, 1987 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.
