The Web3D Consortium promotes the development of quality tools for X3D visualizations by open-source and proprietary software.

XML-encoded X3D scenes can be validated through any DTD and Schema tool.

In addition, numerous open examples detail the many features of our Standards and Specifications: The Web3D Example Scene Archives provide equivalent scenes in a number of encodings (XML, Classic, JSON, Binary) and includes the NIST Conformance Suite.
