[x3d-public] Castle Game Engine / Castle Model Viewer news: IFC support, work on the web target

[John Carlson]

Michalis,

This looks like a quantum leap in capability. Great work!

Will we see the ability to include any JavaScript in an X3D Script node?
Is this already available?  I heard some rumors from Aaron.  Any
instructions on doing something like X3DOM editor or X_ITE playground,
especially with the mobile model viewer?

Thanks!

John
