Early experiments in molecular graphics.Top, dot surface and covalent skeleton displayed interactively with the Evans and Sutherland MultiPicture System with custom software. Two hand-drawn illustrations of packing of DNA decanucleotides in crystal lattices. Bottom, stereo pair of a bond diagram created using ORTEP and output on a pen plotter, with extra lines depicting the contacts between neighboring molecules in a crystal lattice. Raster image of a drug complex with DNA using shiny Phong shading, and volume-rendered image of electron density of a drug in the minor groove of DNA, both created with custom computer graphics software.
