Shouldn't the normal be multiplied by the inverse transpose of the modelview

OpenSceneGraph/osgEarth vs VulkanSceneGraph/vsgpagedlod Hi All,Over the
If your database is in geocentric coordinates, a z value of zero puts you at
the equator somewhere...most likely where there is no terrain data.
Make sure your geocentric coordinates are correct for where you have terrain
data.

If you change to geocentric coordinates, the "up" vector is the normal to the
spheriod at the XYZ location. I'm not sure what you mean by the Y coordinate.
