Terrain and sky modeling and rendering: Gavin MillerThe terrain was modeled using a variant of fractals which overcame the "creasing problem" and the water used an analytic form of distributed ray-tracing for terrain, hence the streaks in the water. The details are explained in my 1986 SIGGRAPH paper.
