X3Dv4 Public Working Draft
The Web3D Consortium is happy to release the X3D4 Committee Draft (CD) Specification which is functionally complete and supported by multiple implementations. Advanced new capabilities include HTML5 integration, Khronos glTF model rendering, and high-fidelity Web Audio.
Much X3D4 execution work is accelerating forward on implementation and evaluation of example models, to good effect. Have fun with X3Dv4!
