Just a quick update for the IM developers and anyone using VRML export.  It looks like there is a small bug in the ImageModeler VRML exporter.  The VRML spec says that the camera FOV should be the reported as the _smaller_ of the horizontal or vertical FOVs.  It seems that IM exports the horizontal FOV no matter what.  This probably isn't a problem for may people - sometimes it may make your scene look a little far away initially.  I'll email this to customer support as well.
