A Novel Monte Carlo Noise Reduction Operator - The authors extended the standard bilateral filtering method and built a new local adaptive noise reduction kernel. The new operator suppresses the outliers and interpixel incoherence in a noniterative way.

Rendering Grass in Real Time with Dynamic Lighting - A real-time grass-rendering technique that works for large, arbitrary terrains exhibits 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.
