Bent Normals and Cones in Screen-space
(The Eurographics Association, 2011)
Ambient occlusion (AO) is a popular technique for real-time as well as offline rendering. One of its benefits is a gain in efficiency due to the fact that occlusion and shading are decoupled which results in an average ...
A Mathematical Model and Calibration Procedure for Galvanometric Laser Scanning Systems
(The Eurographics Association, 2011)
Laser galvanometric scanning systems are commonly used in various fields such as three dimensional scanning, medical imaging, material processing, measurement devices and laser display systems. The systems of such kind ...
Partial Symmetry Detection in Volume Data
(The Eurographics Association, 2011)
In this paper, we present an algorithm for detecting partial Euclidean symmetries in volume data. Our algorithm finds subsets in voxel data that map to each other approximately under translations, rotations, and reflections. ...
