Last year I developed an ActiveX object using VTK which enabled me to embed a viewer in an Internet Explorer browser page, and a similar Netscape Plugin version to run on Netscape.  It can be a fairly thin layer over top of the VTK code.  I don't think there are any online demo's anymore, but you can access the installation for the version that I created from:

The way this was developed was to accept either a filename or URL to specify the location of polydata information which it would draw into the ActiveX window.  It took very little research into ActiveX to enable us to create a thin GUI layer to access the VTK functionality from the browser window.  One problem with this approach is that, for now, you really need to develop an ActiveX package and a Netscape Plugin package.  Much of the code can be shared, however, and the Netscape API is similarly easy to wrap around VTK.

Hope that's of interest.
Kevin.
