This code availability enables straightforward upgrade of diverse existing VRML browser software. X3D is only 3D technology providing such interoperability gains for scene graph geometry and behavior. We do not wish to be part of the long-running API wars. Rather, we wish to maximize file format interoperability wiyh many APIs. This increases broad interchange of interactive 3D content over the Web.
Standardization can come later, after implementation and authoring experience.
Recommended practices can proceed in parallel with X3D development. Your feedback is welcome.
