Global Variables

ifstream in_stream Variable
Intended for inputting files of input code. However, 3DLDF does not currently have a routine for reading input code. in_stream is currently attached to the file ldfinput.ldf by initialize_io() (see I/O Functions). in_stream is read in character-by-character in main(), however this serves no useful purpose as yet.

ofstream out_stream Variable
Used for writing the file of MetaPost code, which is 3DLDF's output. Currently attached to the file by initialize_io() (see I/O Functions).

ofstream tex_stream Variable
TeX code can be written to a file through tex_stream, if desired. 3DLDF makes no use of it itself. Currently attached to subpersp.tex by initialize_io() (see I/O Functions).
