A program for three‐dimensional rendering and interactive model refinement, ASSA , is presented. The program permits the simultaneous display and manipulation of low‐resolution envelope models obtained from solution‐scattering data and the crystallographic or electron microscopic models in the Brookhaven Protein Data Bank format. ASSA is coupled with the shape‐determination program of Svergun, Volkov, Kozin, Stuhrmann, Barberato & Koch [ J. Appl. Cryst. (1997). 30 , 000–000], thus allowing one to monitor the shape determination process in real time. The program ASSA is written in C using the PHIGS+ standard for the three‐dimensional solid rendering and the XView and XLib libraries for the menu‐driven user interface. The system runs on a Sun SPARC ZX‐20 workstation; a simplified IBM‐PC version is also available.
