INTRO(3T)              AVIATOR TERRAIN LIBRARY FUNCTIONS              INTRO(3T)



NAME
        intro - introduction to Aviator Terrain Library

DESCRIPTION
        Section 3T describes user-level Aviator Terrain Library routines.
        Aviator Terrain Library is used for generating and maintaining
        custom terrain data files for use with the flight simulator program
        Aviator.

        Pages of special interest have been categorized as follows:

        3T      Aviator Terrain Library routines.

FILES
        /usr/games/aviator/atl/h/atl.h
        /usr/games/aviator/atl/lib/libatl.a
        /usr/games/aviator/passwords
        /usr/games/aviator/terrain/???_???
        /usr/games/aviator/terrain/???_???.c32

ENVIRONMENT
        The environment variable AVIATOR_HOME points to the home directory for
        aviator, if it is other than /usr/games/aviator.  AVIATOR_PASSWORDS
        points to the file that contains the password file passwords, if it is
        other than /usr/games/aviator/passwords or ${AVIATOR_HOME}/passwords.
        passwords contains the password needed to use atl_color().  The
        following are examples of how to set AVIATOR_HOME and
        AVIATOR_PASSWORDS:

                setenv AVIATOR_HOME      /home/bigdisk/aviator
                setenv AVIATOR_PASSWORDS /home/bigdisk/aviator/passwords

WARNINGS
        The ATL terrain file formats may change from one release of aviator to
        the next so that new features may be incorporated.  The terrain file
        generated for a given version of ATL will only work with the same
        version of aviator binary.
