NAME
ivdowngrade - converts Inventor 2.1 files to the
Inventor 2.0 and 1.0 formats
SYNOPSIS
ivdowngrade [-v targetVersion] [infile
outfile | infile ]
DESCRIPTION
ivdowngrade reads the input file
infile and converts it to the Inventor format specified by
-v targetVersion, either 1.0 or 2.0. If the -v option is not
specified, an Inventor V2.0 file will be generated. The input file
can be in Inventor or VRML format. The output will always be in
ascii format. If no output file is specified, ivdowngrade writes to
stdout. If no input file is specified as well, ivdowngrade reads
from stdin.
EXAMPLE
- ivdowngrade -v 1.0 foo.iv moo.iv
- Downgrades the file foo.iv to Inventor V1.0 format, writing to
moo.iv.
- ivdowngrade goo.iv
- Downgrades the file goo.iv to Inventor V2.0 format, writing to
stdout.
NOTES
Because of differences between the 1.0 and 2.0 file
formats, some data may be lost during the conversion to 1.0. For
instance, the 2.0 file format for SoSeparator contains
fields for caching and culling, but the 1.0 format for
SoSeparator has no fields. This information is lost during
the conversion process.
No data is lost going from the 2.1 to the 2.0 format.
