en Limba Engleză Paperback – 27 apr 2001

Computer Graphics through Key Mathematics introduces the mathematics that support computer graphics on a 'need to know' basis. Its approach means you don't have to do advanced mathematical manipulation in order to understand the capabilities, scope and limitations of the computer graphics systems that create impressive images. The book is written in a clear, easy-to-understand way and is aimed at all those who have missed out on an extended mathematical education but who are studying or working in areas where computer graphics or 3D design plays an vital part. All those who have no formal training but who want to understand the foundations of computer graphics systems should read this book, as should mathematicians who want to understand how their subject is used in computer image synthesis.
