Yeah you can use Acrobat Pro Extended, which comes with a small 3D application, for loading up Collada files, so you need to get a Maya Collada Exporter plugin as well. Once you load Collada files into this application you can export an interactive PDF, which can be embedded (using an HTML tag) directly on to a page. The resulting PDF is quite nice, because you have full camera control, and can even interactively slice the model, to see the inside. You can also setup camera bookmarks before making PDF, so user can see predefined views. Sorry I haven't done this process in a long time, and I forget any more specifics of doing it.
Note: All geometry must be polygon, and only a low polygon count is recommended. Multiple materials can be created in Adobe's 3D Viewing application, but rendering quality is very low.
