Hi Cory,
Texture coordinates is a basic way to apply a texture on a geometry.
For each vertex, you give a 2D coordinate data to associate a vertex and a
texture point. OpenGl will interpolate the texture pixel between each
vertex, depending on theses coordinates.
The 2D texture coordinate have

only be compatible with osg 2.8

With osgEarth you can generate a terrain model at run-time by connecting

Now, you can't change a uniform during a single OpenGL traversal, of course (i.e.,

That's right J-S. osgEarth never actually writes any terrain geometry to
