Hi Markus, Assuming you're using a simple grayscale image as your heightmap. A very quick way would be to use the osg::HeightField shape in conjunction with the osg::ShapeDrawable class. You would load the image into an osg::Image class and then extract the height information, in this case the pixel value into the osg::HeightField array. If that's then added to a ShapeDrawable and in turn to a geode you'll get it up on screen in no time.
Be aware that osg::HeightField doesn't compute very accurate normals (i think it uses 4 point normals) and should only really be used as a data structure or for prototyping. Hope that helps.
