Abstract : This report describes ICCanvas, a computer program which creates and displays isosurfaces on 3D scalar fields. ICCanvas runs under Microsoft Windows 3.1 on computers with 4 MB or more of RAM. Its three program files total less than 150 KB, and its fully documented custom file format for scalar fields is highly compressed. The ICCanvas distribution disk includes C language source code for creating IC format data files. ICCanvas was developed for personal computer visualization of 3D density data created by the TASS and DICE- MAZ nuclear cloud hydrodynamic codes. Its scalar field data model is sufficiently general that it may also be used to view the results of 3D medical imaging (e.g., Cr and MRI), geological surveys, or the tabulated values of almost any function of three variables. ICCanvas gives users interactive control over the orientation of the view and the choice between wireframe, faceted and Gouraud-shaded rendering. The program's display can be saved in Windows BMP, PC Paintbrush PCX, and Macintosh PICT formats, and the geometry of the surfaces it creates can be saved as AutoCAD DXF and Wa- vefront OBJ files. The program includes extensive on-line help.
