## Overview of Queried Function Groups

This section contains an overview of all the function groups available via the SciTech SNAP Graphics Architecture API. Unlike the global functions, these functions are not called directly, but instead are called via groups of function pointers that are returned by the GA_queryFunctions function. As such each function group is relative to the specific group of functions that the function pointer belongs in. In the detailed function reference section, these functions are actually documented in the data structures section, underneath the named data structure containing the function pointers themselves.
