Query: A Waste of Paper

The title of this review says it all. I'm hard pressed to think of any arena in which this boook might server some purpose other than book-end. Too small for a boat anchor...This book is not about OpenGL programming. It's about the authors highly specific, extremely limited system for rendering a small set of surfaces described by mathematical expressions. Don't make the mistake of thinking that the author has developed a general purpose surface rendering-graphing system. He hasn't. Likewise, don't make the mistake of thinking this is some open-ended system that can be extended to a general-purpose (read 'useful') rendering/graphing system. It is too limited to be a useful graphics/mathematical tool, and it certainly isn't going to teach anyone anything about OpenGL.
