To me, this type of simple viewing solution may present a good alternative to 3D PDF for sharing basic visualization models to the Client and other non-design-team stakeholders.  The key issue will be ensuring the web browser of the target user supports WebGL.  I think it should also provide a constrained orbit mode.

Example Revit Export to view in WebGL

The export includes:
– Visible categories of the active 3D-View
– Solids and geometric instances inside the section box
The export itself creates a wpm file (WebGL-Publisher Model) and a html file which displays the exported model.
In addition to that all needed textures and JavaScript libraries are copied to the target directory.
