<P><FONT SIZE=2 FACE="Courier New">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:</FONT></P>

<P><FONT SIZE=2 FACE="Courier New">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.</FONT></P>
<P><FONT SIZE=2 FACE="Courier New">Hope that's of interest.</FONT>
