Hi Peter, osg::State in svn/trunk and later 2.9.x series has support for assigning a osg_ModelViewProjectMatrix, when you build for GL 3 or GLES 2 it'll use this by default. You can switch this on via: state.setUseModelViewAndProjectionUniforms(true); Robert. On Wed, Sep 29, 2010 at 8:21

Re: [osg-users] convertLatLongHeightToXYZ

Yes, they're both equivalent in that they return position info but the former returns a matrix for you to use in your transform node so that your model will be positioned correctly on the spheroid. I believe the up vector of the model will then match the up vector at that position on the spheroid
