Pointing Facilitation Techniques for 3D Object Selection in Virtual Environments
(Argelaguet Sanz, 2011-07-04)
Selection is one of the fundamental tasks in virtual reality applications and the initial task for most common user's interactions in a virtual environment. In this thesis we analyze major factors influencing selection ...
Visual Semantic Analysis to Support Semi Automatic Modeling of Service Descriptions
(Bhatti, 2011-06-10)
A new trend Web service ecosystems for Service-Oriented Architectures (SOAs) and Web services is emerging. Services can be offered and traded like products in these ecosystems. The explicit formalization of services' ...
Symmetry in 3D Shapes - Analysis and Applications to Model Synthesis
(Bokeloh, 2011-11-29)
Symmetry is an essential property of a shapes' appearance and presents a source of information for structure-aware deformation and model synthesis. This thesis proposes feature-based methods to detect symmetry and regularity ...
Multiresolution Techniques for Real-Time Visualization of Urban Environments and Terrains
(Di Benedetto, 2011-06-21)
In recent times we are witnessing a steep increase in the availability of data comingfrom real-life environments. Nowadays, virtually everyone connected to the Internetmay have instant access to a tremendous amount of data ...
Visually Pleasing Real-time Global Illumination Rendering for Fully-dynamic Scenes
(Dong, 2011-03-03)
Global illumination (GI) rendering plays a crucial role in the photo-realistic rendering of virtual scenes. With the rapid development of graphics hardware, GI has become increasingly attractive even for real-time ...
Error-Concealed Image-based Rendering
(Eisemann, 2011-07-06)
Creating photo-realistic images has been one of the major goals in computer graphics since its early days. Instead of modeling the complexity of nature with standard modeling tools, imagebased approaches aim at exploiting ...
Visualization and Graphical Processing of Volume Data
(Gavrilescu, 2011-10-17)
The extraction and visualization of information from volume data constitute important research avenues in computer graphics and imaging. The rapid development of GPUs with increasing computational power has made it possible ...
Path Sampling Techniques for Efficient Light Transport Simulation
(2015-06)
Reproducing the interactions between light and matter in a physically accurate way can significantly improve the realistic appearance of synthetic images, however such effects can be very computationally expensive to ...
Quadrilateral Surface Mesh Generationfor Animation and Simulation
(Bommes, 2012-10-11)
Accurately describing the geometry of objects in a digital environment, i.e. computers, isan essential ingredient in many of nowadays applications. Often it is desired to forecastthe behavior of real phenomena which depend ...
A Frequency Analysis of Light Transport: from Theory to Implementation
(Belcour, 2012-10-30)
The simulation of complex light effects such as depth-of-field, motionblur or scattering in participating media requires a tremendous amountof computation. But the resulting pictures are often blurry. We claimthat those ...
