Read one or more files in OFF format, process them, and write them into a single file.

input_files: input files in OFF format, or if not given the program reads from standard input

-h: program help
-O: orient the faces (if possible)
-s: skeleton, remove faces and write edges as two-edged faces (digons)
-E: turn edges into (non-planar) faces
-S: project onto unit sphere centred at origin
-D <filt>: digon filter, d - remove faces which aren't digons, x - remove digons
-d <dgts>: number of significant digits for output (default 17) or if negative then the number of digits after the decimal point
-o <file>: write output to file, if this option is not used the program writes to standard output

Merge two file into a third

   off_util -o file3.off file1.off file2.off

This program replaces off_merge for file merging.

Option -E is like the join operation in Conway Notation.

The digon filter can used in conjuction with off_color -e to strip the coloured edges, or extract them into a separate file.
