I made a cool online tool using Castle Game Engine:
It allows to
- Convert from any format supported by Castle Game Engine (glTF, X3D, VRML, Wavefront OBJ, STL, Collada, 3DS, MD3, Spine JSON…).
… into X3D, in XML or Classic (VRML) encoding.
Underneath, it uses tovrmlx3d (command-line application distributed
together with view3dscene).
It’s free to use for everyone. It’s of course open-source, both the tovrmlx3d and view3dscene, and a set of scripts (PHP, Docker and shell scripts) to make it work as an online tool in a secure and reliable way.
More information on the tool page. Give it a shot, test your models on it! 🙂
