Computer Graphics PGS

Some of the most exciting advances to have taken place in the computer industry have happened in the area of computer graphics. Most notably, and what most often comes to mind, are the advances which have taken place in the media of movies and video gaming.

While computer graphics as a separate and distinct discipline has for a long time been part of a number of secondary school, trade school and university curricula, teaching the subject remains a challenging task. The Phedias Graphics System (PGS) is an educational tool which was originally developed to facilitate learning of computer graphics in an object-oriented environment. PGS, like most of the full-featured computer graphics systems, is able to create renderings by utilizing several different rendering algorithms including ray tracing and simple z-buffering.

It has many advantages over conventional project environments and approaches to teaching computer

graphics such as writing software from scratch or using commercial systems such as OpenGL. Other advantages include the following (Phedias Graphics System Announcement Page, 2001):

PGS separates rendering and modeling, allowing the differences and relationships between the two be to easily understood.

PGS supports multiple rendering methodologies including Z-buffering and ray tracing.

Sections of PGS are easily replaced for student projects

PGS has been around since 1997 when it was first for teaching computer graphics to undergraduate students at Dartmouth College.

In order to extend its functionality and scope, a radiosity-based renderer has been added to the system. This paper discusses the implementation of the new renderer in the PGS system as well as additional topics about the system and the general field of radiosity rendering.

Computer generated images are usually created by utilizing a technique commonly referred to as ôray tracing.ö While this is the dominant method appli...
