Raster3D Version 2.0 is a program suite for the production of photorealistic molecular graphics images. The code is hardware independent, and is particularly suited for use in producing large raster images of macromolecules for output to a film recorder or high-quality color printer. The Raster3D suite contains programs for composing illustrations of space-filling models, ball-and-stick models and ribbon-and-cylinder representations. It may also be used to render figures composed using other graphics tools, notably the widely used program Molscript [Kraulis (1991). J. Appl. Cryst. 24, 946-950].
