Rendering Grass in Real Time with Dynamic Lighting
Kévin Boulanger, Sumanta N. Pattanaik, Kadi Bouatouch · IEEE Computer Graphics and Applications · 2009
The authors present a real-time grass rendering technique that works for large, arbitrary terrains with dynamic lighting, shadows, and a good parallax effect. A novel combination of geometry and lit volume slices provides accurate, per-pixel lighting. A fast grass-density management scheme allows the rendering of arbitrarily shaped patches of grass.
