shadows

I'm creating an infinite terrain engine, which generates the terrain either with fractals or noise. How can I make dynamic shadows for the sun on this terrain, if I don't know in advance what will be rendered in front of the sun.

My terrain: The sun is the only light, it is directional, my terrain is generated on a plane which is positioned before the camera, frustum culled and fits the size of the viewing frustum. It is height mapped with generated noise texture, and using tessellation shaders on it.

I'm developing a procedural terrain class at the moment and am stuck on the correct design pattern. The terrain is 2D and is constructed from a series of (x,y) points.
