Improving Shadow Map Filtering with Statistical Analysis
(The Eurographics Association, 2011)
Shadow maps are widely used in real-time applications. Shadow maps cannot be filtered linearly as regular textures, thus undersampling leads to severe aliasing. This problem has been attacked by methods that transform the ...
Efficient Feature-preserving Local Projection Operator for Geometry Reconstruction
(The Eurographics Association, 2011)
This paper proposes an efficient and feature-preserving locally optimal projection operator (FLOP) for geometry reconstruction. We first develop a bilateral weighted local optimal projection operator. We then present a ...
