The computer program CHIEF [G. W. Benthien, D. Barach, and D. Gillette, “CHIEF Users Manual,” Naval Ocean Systems Center Report 920 (Sept. 1988)] is designed to obtain approximate solutions to exterior steady‐state acoustic radiation problems for surfaces of arbitrary shapes vibrating with a prescribed normal velocity. Being unable to view the shapes defined by CHIEF can lead to many difficult debugging problems as well as incorrect solutions. DISPLAY3D provides points as though the data were locations on a three‐dimensional surface on a solid and a description of how these points are connected. DISPLAY3D has several options that make it a versatile package. The code permits the user to change the orientation from which the data are viewed. DISPLAY3D also provides the option of viewing the direction of the normal velocity vector as defined by CHIEF. These options, as well as others, will be explained in detail. [Work supported by ONT.]
