Although any programming work is more interesting than most people think, it is especially exciting if it results in graphics output based on almost forgotten mathematical theory that turns out to be useful after all. This book uses the C++ programming language and the Qt framework to implement some important graphics algorithms and it shows the reader how to write programs that are reliable, well-readable, fast, and easy to use. There are many non-trivial ready-to-run programs in the book that can be compiled and run both on Windows and Linux platforms.
