VRML 1.0 to VRML 2.0

The only command line VRML 1.0 to VRML 2.0 converter known to still exist is the Windows based vrml1tovrml2.exe. I have written a wrapper, vr1tovr2.exe, to give vrml1tovrml2 both stdin and stdout support. That is, you can now used named pipes for data flow through vrml1tovrml2.

Note that since this program only runs on Windows there is no corresponding command line program for Unix. If anyone knows of an open source application to do this please let me know.

Historical links, and research, some via the Wayback Machine

• Had a link to Vrml1ToVrml.exe giving the clue it was from SGI
• Was about a program called vrml1to2
• Cosmosoftware had a page listing various utilities
• A program called Instant Reality
• Was the NIST page on VRML97
• Was about a package for conversions involving VRML97 and X3D files
• Was about a Package for conversions involving VRML97 and X3D files

The VRML Player Cortona will allow direct viewing of VRML 1.0. It ran under Internet Explorer before Windows 11, but will still run under Microsoft Edge when opening a model on a tab in Internet Explorer mode.

The state of the art is X3D. https://www.web3d.org/x3d/content/examples/ConformanceNist/index.html

vr1tovr2.exe, written by Roger Kaufman <polyhedrasmith@gmail.com> Apparently by SGI, vrm1tovrml2.exe will convert VRML 1.0 to VRML 2.0. Part of Cosmo Player, it was made into a Windows command line program. It requires a dynamic linked library CP_VRML1TO2.dll. The program has been seen distributed about the web as this pair of files. To install, unzip the two files, which must remain together, into a directory which is in your path. Note: If using Windows WSL to run vr1tovr2, then vrml1tovrml2.exe and CP_VRML1TO2.dll must be placed a directory in the Windows path such as the C:/Windows directory I have written a wrapper, vr1tovr2.exe, to give vrml1tovrml2 both stdin and stdout support. That is, you can now used named pipes for data flow through vrml1tovrml2. I have added -p, a parameter, to pass any non-vrml 1.0 file to output unchanged e.g. type 'a non-VRML 1.0 file" | vr1tovr2 -p > 'a non-VRML 1.0 file unchanged' In that way you can use vr1tovr2 -p in a script without having to check if it is being sent a valid VRML 1.0 file use vr1tovr2 -h for avaiable parameters. Usage: vr1tovr2 [options] Convert vrml 1.0 to vrml 2.0 via vrml1tovrml2.exe (external program). If input_file is not given the program reads from standard input. Options -h,--help this help message (run 'off_util -H help' for general help) --version version information -p pass any non-vrml 1.0 file to output unchanged -o <file> file name for output (otherwise prints to stdout)
