Support for Vec3d's for geometry in the OSG is relatively new thing and not all elements support them, Tessellator included. Internal the GLU tessellator does use double vertices so there is the potentially for adding support for Vec3dArray into osgUtil::Tessellator, however, one will need to modify the internals in a number of places to make this possible. As a general comment Vec3d's for geometry will still be very very inefficient to render on almost all graphics hardware so it's not recommend to use double for geometry for anything other than importing GIS data. Once the data is in the scene graph it's best to decorate your subgraph MatrixTransform the places a subgraph into it's final position in space, whilst the subgraph is moved to local coordinate frame.
