1. Press Release.

[1.1]	Web3D, Khronos Liaison Press Release

======================================
"Web3D Consortium and Khronos Group deepen cooperation on open standards for 3D on the Web"

Web3D and Khronos have signed a liaison agreement to cooperatively advance their standards to support Web-based 3D visualization, modeling and streaming. This agreement formalizes the mutual interest of the two organizations to build cohesive ecosystems of related technology standards including X3D and glTF.

======================================

This is great news.  Thanks to everyone involved who has gotten us to this point.

It is interesting to consider that it has taken X3D at least a decade to "catch up" and regain technical parity for rendering.  This is first due to steady stable progress by many people.  Today's X3D4 capabilities for physically based rendering (PBR) and other advanced techniques are primarily due to the design and implementation efforts of Michalis Kamburelis.

Further study recommended.  Please see his work for direct examples and detailed explanations of how all this works together.
