Detailed Description

R T _ I

Definitions for librt which are specific to the particular model being processed, one copy for each model. Initially, a pointer to this is returned from rt_dirbuild().

During gettree processing, the most time consuming step is searching the list of existing solids to see if a new solid is actually an identical instance of a previous solid. Therefore, the list has been divided into several lists. The same macros & hash value that accesses the dbi_Head[] array are used here. The hash value is computed by db_dirhash().
