INTRODUCTION
Welcome to the 'Computer Graphics Companion' Online book. During my time as a graphics programmer I was always searching for a single
reference for formulas and algorithms. Something I could have on my Desktop always waiting for that questions ‘How
do I draw a circle really quickly?’ or ‘What’s the formula for the area of a hemisphere?’ As a CAD developer I always had this information scribbled in various notebooks.
Finally I decided I would put in all Online. A single file could easily have all the data to hand and could be
shared with others searching the same answers. Thus was born the ‘Computer
Graphics Companion’ I've tried to gather as much information as possible on all forms of computer graphic
creation along with tips to go that extra bit further to get that little bit more from your computer. Computer Graphic fundamentals are always the same no matter what type of machine
used. The only things that ever change are your display type, the colour palette, etc. The fundamental algorithms
for drawing a line or a circle will always remain the same no matter what platform your software runs on. The base
element that changes from platform to platform is actually how you write a pixel to the screen. In taking this
approach all the information found here is easily transportable to any platform you desire. Each section of this book contains a variety of information. Firstly each item is
described in its mathematical representation, followed by a piece of 'C' code showing its implementation. I hope that having read this book (Many Times!), you will have the tools to experiment with your computer graphics routines, and create
new faster programs using some of the techniques you have learned here. Remember though, creating new algorithms
takes time and effort, but is worth it in the end. Damian Scattergood
