Hi Res Graphics And Animation Using Assembly Language

A Graphics Toolkit teaches you the art of creating graphical libraries for use in games and other programs on the Apple II computer. Tutorial articles guide you through machine language and BASIC programs that can be used in your own games. Features: - Intricacies of graphics on the Apple II and general graphics algorithms. are explored, along with creation of the tools needed to make your own graphics and graphics routines. - Tutorials for many wonderful routines include: Hi-Res Graphics, HGR and HGR2, Hi-Res Graphics, Line-Drawing, Graphics Windows, Special Effects, Shape-Drawing, Block Shapes, Animation, Double Buffering, Non-Animation Shapes, Shapes Partially Within the Graphics Window, and many Demos. Routines are available on a disk image. - Based on the popular "Graphics Toolkit" articles from 1984 to 1986 in Call-A.P.P.L.E. magazine. - Some knowledge of 6502 assembly language and Applesoft BASIC is helpful, as well as Apple II graphics in general.

Note: This is the second printing. It contains all of the corrections as of May 2017 as well as an updated back cover. Roger Wagner's Assembly Lines articles originally appeared in Softalk magazine from October 1980 to June 1983. The first fifteen articles were reprinted in 1982 in Assembly Lines: The Book. Now, for the first time, all thirty-three articles are available in one complete volume. This edition also contains all of the appendices from the original book as well as new appendices on the 65C02, zero-page memory usage, and a beginner's guide to using the Merlin Assembler. The book is designed for students of all ages: the nostalgic programmer enjoying the retro revolution, the newcomer interested in learning low-level assembly coding, or the embedded systems developer using the latest 65C02 chips from Western Design Center. "Roger Wagner didn't just read the first book on programming the Apple computer-he wrote it." - Steve Wozniak

Computer graphics is being used to an increasing extent in the biological disciplines. As hardware costs drop and technological developments intro duce new graphics possibilities, researchers and teachers alike are becoming aware of the value of visual display methods. In this book we introduce the basics of computer graphics from the standpoints of both hardware and software, and review the main areas within biology to which computer graphics have been applied. The com puter graphics literature is vast, and we have not been able to give a full course on graphics techniques in these pages. We have instead tried to give a fairly balanced account of the use of graphics in biology, suitable for the reader with some elementary grounding in computer programming. We have included extensive references both to material cited in the text and to other relevant publications. One of the factors that has fuelled the increase in graphics use is the ease with which the more simple graphics techniques may be implemented on microcomputers. We hav.e, therefore, paid attention to microcomputer graphics as well as graphics techniques suitable for larger machines. Our examples range from simple two-dimensional graph plots to highly complex surface representations of molecules that require sophisticated graphics devices and mainframe computers on which to run. The book is separated into two logical sections. The first part con centrates on general graphics techniques, giving an overview from which the reader will be able to refer to other more specialised texts as required.

No one has done more to conquer the performance limitations of the PC than Michael Abrash, a software engineer for Microsoft. His complete works are contained in this massive volume, including everything he has written about performance coding and real-time graphics. The CD-ROM contains the entire text in Adobe Acrobat 3.0 format, allowing fast searches for specific facts.
