No error was reported, thus it is difficult to explain the error you might have encountered. When running the code, I get
error: 'finite' undefined near line 270, column 270
error: called from
vrml_surf at line 270 column 7

However, the last release of that package was 2012… This is a case of an unmaintained package.
If you are interested in the package to work, you can:
- Contact the maintainer of that package by email Octave Forge - The 'vrml' package
- File a bug report at Savannah Octave Forge - Support/Help (this has by experience almost no chance of getting recognized by the maintainer of an unmaintained package)
- Work on your own fork of the package.
- In accordance with the previous maintainer become new package maintainer and make a new package release.
