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

[John Carlson]

Any hints on how to use window.location.href in JavaScript to get the url
of main scene out of the main URL in the web model viewer to get actual
.x3d URL to load into model viewer, like x3dom editor and x_ite playground?

That is, the .x3d url appears as a parameter to the model viewer url.

Thanks!

John
