[x3d-public] X3D Open Meeting on Physically Based Rendering (PBR) and glTF support

[Anita Havele]

Thank you for attending our open X3D WG meeting today! As we continue 
working on X3D4 specification, major pieces of work in progress are now 
mature and ready to be included in the spec. This open meeting was 
specifically for: glTF lighting and physically based rendering (PBR) 
work. Feedback and reactions are always welcome.

Michalis Kamburelis <https://github.com/michaliskambi/>, author of 
Castle Game Engine (CGE) <https://castle-engine.io/>described and 
demonstrated proposed X3D4 
<https://www.web3d.org/x3dv4-highlights>changes for PBR and glTF 
support.  Several models demonstrating these capabilities were discussed 
along with comparative implementation in other X3D4 players. Thank you, 
Michalis for this excellent work!

Here are some links to the discussions and demos from today’s meeting.

1.PBR why do we need it in X3D:

2.X3D4 |PhysicalMaterialnode. C|onsistent with glTF to facilitate X3D 
and X3D browsers to support glTF.It’s easy to handle glTF by converting 
to X3D nodes "under the hood".

3.Castle Animation: A series of static 3D frames in-lined in a large XML 
file, or external files. Animation shows transition from the first frame 
to the last. Where models are /structurally equal/, intermediate frames 
are created by a linear interpolation to show smooth changes.

6.Demo Models (Share your relevant use case models to add to this 
repository)

Again, thank you for your participation today. Feedback and reactions 
are always welcome. A draft schedule for X3D4 is ready, based on member 
discussions, but we are still watching world events and conference 
delays/cancellations closely.  Meanwhile subscribe to
