Compressive Image Reconstruction in Reduced Union of Subspaces
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present a new compressed sensing framework for reconstruction of incomplete and possibly noisy images and their higher dimensional variants, e.g. animations and light-fields. The algorithm relies on a learning-based ...
T-SAH: Animation Optimized Bounding Volume Hierarchies
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We propose a method for creating a bounding volume hierarchy (BVH) that is optimized for all frames of a given animated scene. The method is based on a novel extension of surface area heuristic to temporal domain (T-SAH). ...
High-Quality Shadows for Streaming Terrain Rendering
(The Eurographics Association, 2015)
Rendering of large, detailed 3D terrains on commodity hardware has become possible through the use of raycasting, data caching and prefetching. Adding dynamic shadows as they appear during a day-night cycle remais a challenge ...
A Dimension-reduced Pressure Solver for Liquid Simulations
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
This work presents a method for efficiently simplifying the pressure projection step in a liquid simulation. We first devise a straightforward dimension reduction technique that dramatically reduces the cost of solving the ...
Multi-Touch Table System for Medical Visualization
(The Eurographics Association, 2015)
Medical imaging plays a central role in a vast range of healthcare practices. While the usefulness of 3D visualizations is well known, the adoption of such technology has previously been limited in many medical areas. This ...
Improving k-buffer Methods via Occupancy Maps
(The Eurographics Association, 2015)
In this work, we investigate an efficient approach to treat fragment racing when computing k-nearest fragments. Based on the observation that knowing the depth position of the k-th fragment we can optimally find the k-closest ...
Improving Sampling-based Motion Control
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We address several limitations of the sampling-based motion control method of Liu et at. [LYvdP 10]. The key insight is to learn from the past control reconstruction trials through sample distribution adaptation. Coupled ...
Partitioned Shadow Volumes
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Real-time shadows remain a challenging problem in computer graphics. In this context, shadow algorithms generally rely either on shadow mapping or shadow volumes. This paper rediscovers an old class of algorithms that build ...
