What you're doing should work. Of course you may have to add interpolation between values if you want to sit on triangles between samples and your interpolation will need to accounte for the triangulation of the terrain subdivision.

You should be able to see it working at least approximately when grabbing simple samples. Get that working approximately then advance to teh interpolation between height samples.
