Pattern Search in Flows based on Similarity of Stream Line Segments
(The Eurographics Association, 2014)We propose a method that allows users to define flow features in form of patterns represented as sparse sets of stream line segments. Our approach finds ''similar'' occurrences in the same or other time steps. Related ... -
Progressive Spectral Ray Differentials
(The Eurographics Association, 2014)Light travelling though refractive objects can lead to beautiful colourful illumination patterns resulting from dispersion on the object interfaces. While this can be accurately simulated by stochastic Monte-Carlo methods, ... -
Real-time Canonical-angle Views in 3D Virtual Cities
(The Eurographics Association, 2014)Virtual city models are useful for navigation planning or the investigation of unknown regions. However, existing rendering systems often fail to provide optimal views during the exploration, introduce occlusions, or show ... -
Real-time Deblocked GPU Rendering of Compressed Volumes
(The Eurographics Association, 2014)The wide majority of current state-of-the-art compressed GPU volume renderers are based on block-transform coding, which is susceptible to blocking artifacts, particularly at low bit-rates. In this paper we address the ... -
Real-time Reflective and Refractive Novel-view Synthesis
(The Eurographics Association, 2014)We extend novel-view image synthesis from the common diffuse and opaque image formation model to the reflective and refractive case. Our approach uses a ray tree of RGBZ images, where each node contains one RGB light path ... -
SOAR: Stochastic Optimization for Affine global point set Registration
(The Eurographics Association, 2014)We introduce a stochastic algorithm for pairwise affine registration of partially overlapping 3D point clouds with unknown point correspondences. The algorithm recovers the globally optimal scale, rotation, and translation ... -
Supporting Urban Search & Rescue Mission Planning through Visualization-Based Analysis
(The Eurographics Association, 2014)We propose a visualization system for incident commanders in urban search & rescue scenarios that supports access path planning for post-disaster structures. Utilizing point cloud data acquired from unmanned robots, ... -
Towards Efficient Online Compression of Incrementally Acquired Point Clouds
(The Eurographics Association, 2014)We present a framework for the online compression of incrementally acquired point cloud data. For this, we extend an existing vector quantization-based offline point cloud compression algorithm to handle the challenges ...
