4. Creating geometry data

The cgview can be used to help create geometry data for an EGS4 calculation. In cgview, CG geometry data of the EGS4 code can be created, and these data are immediately displayed in 3-D figures on the screen for checking. Also, it is possible to save created data. This data can be used as a CG input file in an EGS4 calculation.
