Detailed Description

D B _ I

One of these structures is used to describe each separate instance of a BRL-CAD model database ".g" file.

dbi_filepath is a C-style argv array of places to search when opening related files (such as data files for EBM solids or texture-maps). The array and strings are all dynamically allocated.
