Random objects and lights have the advantage that they we start with the individual triangles and add the objects to them. This way we know each vertex and can find the coordinates of any random point on the triangle without doing a height above terrain test. However, the main effort of the HOT routines are to find the corresponding triangle in the scene graph which you'd need to do if you wanted to place an object at an arbitrary lat/lon.
