Shadow Penumbras for Complex Objects by Depth-Dependent Filtering of Multi-Layer Depth Images
(The Eurographics Association, 1999)
This paper presents an efficient algorithm for filtering multi-layer depth images (MDIs) in order to produce approximate penumbras. The filtering is performed on a MDI that represents the view from the light source. The ...
Hierarchical Image-Based Rendering using Texture Mapping Hardware
(The Eurographics Association, 1999)
Multi-layered depth images containing color and normal information for subobjects in a hierarchical scene model are precomputed with standard zbuffer hardware for six orthogonal views. These are adaptively selected according ...
