内容説明・目次
内容説明
The book covers elementary concepts, from how to produce simple graphical objects using logical coordinates to producing filled regions. The book reinforces concepts with useful and simple examples, then progresses to applied geometry (vectors, polygons) and then onto how to perform rotations and other transformations of graphical objects. In a logical progression of ideas, the reader is introduced to some of the classic graphics algorithms and finally to chapters which cover particular effects such as perspective drawings and hidden-face and hidden-line elimination.
The book also provides a host of ready-to-run programs and worked examples to illuminate general principles and geometric techniques for the creation of both 2D and 3D graphical objects.
