NATO Advanced Study Institute directed by J.E. Bresenham, R.A. Earnshaw, M.L.V. Pitteway

Algorithms provide the basic foundation for allcomputational processes. This volume presents algorithms atthe foundational level and also at the various levelsbetween this level and the user application. Some of thesealgorithms are classical and have become well established inthe field. This material is therefore a rich source ofinformation and is still relevant and up to date. The basicprimitives of computer graphics have remained unchanged:lines, circles, conics, curves and characters. This volumecontains reference material in all these areas. The higherlevelsof contouring and surface drawing are also wellcovered. Developments in hardware architectures havecontinued since the first printing, but the basic principlesof hardware/software trade-offs remain valid. This reprintis being published as a Study Edition to make the materialmore accessible to students and researchers in the field ofcomputer graphics andits applications. The continuingpopularity of the original book demonstrates the value andtimeliness of its contents.
