It is footbones.ply.

**Tip** : Now that almost every C++ example is interactive in the browser, you can discover the data file being used with a trick. Click on the “Interactive example” and open developer console to see which file was loaded under `data` directory. Remove the `.js` suffix and you’ve your filename. See the screenshot for reference.

I wonder if it’s possible to automatically find this and show the file name above the viewer. Even better if it could just print all arguments.
