Hi,
I have a osgDEM produced geocentric database.
I looked into the geometryTechnique implementation to see if I somehow
can access the height of the vertices above the ellipsoid in the vertex
shader.
Unfortunately I don't have any idea how to calculate this from the give
matrices. Is this information somehow available at all?
My plan is to overwrite some of the functionality in the
geometryTechnique to pass the appropriate matrices to the shader.
Anyone having an idea?
