d21ddc4f 59//! The Interactive Context allows you to manage graphic behavior and selection of Interactive Objects in one or more viewers.
60//! Class methods make this highly transparent.
61//! It is essential to remember that an Interactive Object which is already known by the Interactive Context must be modified using Context methods.
62//! You can only directly call the methods available for an Interactive Object if it has not been loaded into an Interactive Context.
63//!
64//! Each selectable object must specify the selection mode that is
65//! responsible for selection of object as a whole (global selection mode).
66//! Interactive context itself supports decomposed object selection with selection filters support.
67//! By default, global selection mode is equal to 0, but it might be redefined if needed.
