Fast Accurate Soft Shadows with Adaptive Light Source Sampling
(The Eurographics Association, 2012)
Physically accurate soft shadows in 3D applications can be simulated by taking multiple samples from all over the area light source and accumulating them. Due to the unpredictability of the size of the penumbra regions, ...
Fast and Robust Landmark Tracking in X-ray Locomotion Sequences Containing Severe Occlusions
(The Eurographics Association, 2012)
Recent advances in the understanding of animal locomotion have proven it to be a key element of many fields in biology, motion science, and robotics. For the analysis of walking animals, high-speed x-ray videography is ...
Design and Fabrication of Faceted Mirror Arrays for Light Field Capture
(The Eurographics Association, 2012)
The high resolution of digital cameras has made single-shot, single-sensor acquisition of light fields feasible, though considerable design effort is still necessary in order to construct the necessary collection of optical ...
Adaptive Treelet Meshes for Efficient Streak-Surface Visualization on the GPU
(The Eurographics Association, 2012)
We describe a novel adaptive mesh representation for streak-surfaces. The surface is represented as a mesh of small trees of initial depth zero (treelets). This mesh representation allows for efficient integration, refinement, ...
Spectral Analysis of Higher-Order and BFECC Texture Advection
(The Eurographics Association, 2012)
We present a spectral analysis of higher-order texture advection in combination with Back and Forth Error Compensation and Correction (BFECC). Semi-Lagrangian texture advection techniques exhibit high numerical diffusion, ...
A Mixed Shape Space for Fast Interpolation of Articulated Shapes
(The Eurographics Association, 2012)
Interpolation between compatible triangle meshes that represent different poses of some object is a fundamental operation in geometry processing. A common approach is to consider the static input shapes as points in a ...
3D Shape Matching based on Geodesic Distance Distributions
(The Eurographics Association, 2012)
In this work, we present a signature for 3D shapes which is based on the distribution of geodesic distances. Our shape descriptor is invariant with respect to rotation and scaling as well as articulations of the object. ...
Visualizing Solar Dynamics Data
(The Eurographics Association, 2012)
Solar dynamics data, particularly those from the Solar Dynamics Observatory, are now available in a sheer volume that is hard to investigate with traditional visualization tools, which mainly display 2D images. While the ...
GPU-accelerated Interactive Material Aging
(The Eurographics Association, 2012)
A photorealistic appearance of a 3D scene is required in many applications today. Thereby, one vital aspect is the usage of realistic materials, for which a broad variety of reflectance models is available. When directly ...
An Efficient Trim Structure for Rendering Large B-Rep Models
(The Eurographics Association, 2012)
We present a multiresolution trim structure for fast and accurate B-Rep model visualization. To get a good tradeoff between performance and visual accuracy, we propose to use a vectorial but approximated representation of ...
