This book will enable you to explore and exploit fully the powerful graphics capabilities of your Electron. Although the authors assume that the reader has some knowledge of Basic programming and elementary geometry, the inclusion of many worked examples and program listings will enable the complete beginner in graphics to make quick progress in learning how to draw and manipulate two- and three-dimensional pictures. Two software cassettes containing most of the larger program listings given in the book are available. For details of these, see the appendix. Ian O. Angell and Brian J. Jones have also written similar books for the BBC Microcomputer and the Sinclair ZX Spectrum.
