Advanced Graphics with the Sinclair ZX Spectrum by I O Angell and B J Jones is published by Macmillan Press. The authors are obviously academics, as the book seems to be aimed at those with a great technical understanding of the Spectrum and also a knowledge of Cartesian Co-ordinate geometry. It is written rather like a treatise, with many references to other books in the main text.
It is well-presented and provides plenty of technical information. The authors show how to develop arcade-quality graphics and also go into the realms of three-dimensional animation. The problem is that many Spectrum users would lose their way in the book, not because of any failing on their part but because of the authors' narrative style. Advanced Graphics with the Sinclair ZX Spectrum costs £9.95.
