Microcomputer-based three-dimensional stereoscopic macromolecular graphics display

Software which permits an IBM AT and two IBM Professional Graphics Displays to be used to display high-quality three-dimensional space-filling stereoscopic images of macromolecules is described. Stereo image pairs generated on two screens are visually fused using a simple mirror system to provide binocular depth perception. Images are colored to identify atomic type, residue type, charge or hydrophobicity according to user-specified codes and can be rotated and rescaled. Macromolecules containing over 16,000 atoms can be rapidly drawn using Brookhaven Protein Data Bank or user-supplied coordinates.
