Image-Based Flow Transfer
(The Eurographics Association, 2014)
Weathering phenomena are ubiquitous to urban environments. In particular, fluid flow becomes a specially representative but difficult phenomenon to reproduce. In order to produce realistic flow effects, it is possible to ...
Stereo-browsing from Calibrated Cameras
(The Eurographics Association, 2014)
Modern Structure-from-Motion (SfM) methods enable the registration of a set of cameras and the reconstruction of the corresponding sparse point cloud of the object/location depicted in the input images. Despite the quality ...
GPU Visualization and Voxelization of Yarn-Level Cloth
(The Eurographics Association, 2014)
Most popular methods in cloth rendering rely on volumetric data in order to model complex optical phenomena such as sub-surface scattering. Previous work represents yarns as a sequence of identical but rotated crosssections. ...
From the Patient to the Surgery - A Complete Computer Vision and Graphics Process
(The Eurographics Association, 2012)
Generating digital information ready to use on a surgery operation from a patient is a complex process. This process involves computer vision techniques, in order to extract digital information from medical images, and ...
Locating Companies in 3D Urban Environments on the Internet
(The Eurographics Association, 2012)
3D visualization is being incorporated in a lot of fields, including Geographic Information Systems (GIS). In addition, the Internet is the most popular method to find information, due to its accessibility. For this reason, ...
Management of 3D Geometry on Portable Devices
(The Eurographics Association, 2012)
The mobile devices has evolutioned quickly in the recent years. The Games industry realized the great potential of these devices and made many developments whose requirements makes devices reach their hardware limits so ...
Adaptive Ray-bundle Tracing with Memory Usage Prediction: Efficient Global Illumination in Large Scenes
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
This paper proposes an adaptive rendering technique for ray-bundle tracing. Ray-bundle tracing can be done by per-pixel linked-list construction on a GPU rasterization pipeline. This rasterization based approach offers ...
Surfel Octrees: A New Scheme for Interactive Inspection of Anatomy Atlases in Client-Server Applications
(The Eurographics Association, 2015)
Nowadays, an increasing interest on tele-medicine and tele-diagnostic solutions can be observed, with client/server architectures for remote inspection of volume image-based medical data which are becoming more and more ...
A New Approach for Perceptually-based Fitting Strokes into Straight Segments
(The Eurographics Association, 2015)
Fitting the strokes of a sketch into geometrical primitives is still an open problem, even for sketches which depict bare line-drawings without annotations. Such sketches comprise only discrete strokes, sequences of points ...
Flow-Induced Inertial Steady Vector Field Topology
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Traditionally, vector field visualization is concerned with 2D and 3D flows. Yet, many concepts can be extended to general dynamical systems, including the higher-dimensional problem of modeling the motion of finite-sized ...
