Computer Graphics and Image Processing Laboratory for Undergraduate Instruction.

Dr. Dennis Mikkelson University of Wisconsin-Stout

The ILI funded laboratory and curriculum development project described in this paper provided UNIX workstations for undergraduate courses in computer graphics and image processing at the University of Wisconsin-Stout. Prior to this project, the computer graphics course was taught on 80286 class personal computers using an implementation of the Graphical Kernel System (GKS) for PASCAL. This project allowed the computer graphics course to move to a C/Unix environment using the Programmer's Hierarchical Interactive Graphics System (PHIGS). Some basic software tools were developed to facilitate the use of PHIGS in an instructional setting. PHIGS in the C/Unix environment has provided an excellent environment for teaching computer graphics. The image processing course has also benefited greatly from the move to the workstation environment. An image processing "workbench" to provide a highly interactive environment for students to develop and test image processing algorithms is under development.

1.0 INTRODUCTION

The Department of Mathematics, Statistics and Computer Science at UW-Stout has offered a course in computer graphics for the last ten years and has offered a course in image processing for the last six years. During this period of time the hardware/software environments available for computer graphics and image processing have evolved rapidly. While the environments have changed rapidly, a solid understanding of the fundamentals of computer graphics and image processing remains the primary goal for these courses.

A major upgrade in the hardware/software available for these courses was provided by the NSF/ILI project described in this paper. The NSF/ILI project provided five DEC 3000 ALPHA/AXP workstations for the graphics and image processing courses. The required PHIGS software was provided by Digital Equipment Corporation under their College Software Library Grant program. This paper gives some considerations for using PHIGS in an introductory computer graphics course and how the project changed the graphics course. The effect of the project on the image processing course is described more briefly, since software development for the image processing
