DESCRIPTION

14       ivdowngrade reads the input file infile and converts it to the Inventor
15       format  specified  by  -v  targetVersion , either 1.0 or 2.0. If the -v
16       option is not specified, an Inventor V2.0 file will be  generated.  The
17       input file can be in Inventor or VRML format. The output will always be
18       in ascii format.  If no output file is specified, ivdowngrade writes to
19       stdout.  If  no input file is specified as well, ivdowngrade reads from
20       stdin.

26             moo.iv.

28       ivdowngrade goo.iv

NOTES

34       Because of differences between the 1.0 and 2.0 file formats, some  data
35       may  be  lost  during the conversion to 1.0. For instance, the 2.0 file
36       format for SoSeparator contains fields for caching and culling, but the
37       1.0 format for SoSeparator has no fields. This information is lost dur‐
38       ing the conversion process.
39       No data is lost going from the 2.1 to the 2.0 format.
