Graphic displays on microcomputers have for some time now been out of the reach of hoobyists because their complexity and high cost. In this book, author Don Inman will show you how, with a minimal knowledge of the BASIC computer language and your TRS-80 computer, you can create graphic displays that only a few years ago were the exclusive turf of owners of bigger computers. The book begins with the basics and works from line drawings through geometrics and on up moving figure animation and more advanced operations. A great handbook on computer graphics for microcomputer owners at all levels of experience.
