High Dynamic Range (HDR) images capture the full range of luminance present in real world scenes, and unlike Low Dynamic Range (LDR) images, can simultaneously contain detailed information in the...
(Guest Editors) Abstract An Improved Physically-Based Soft Shadow Volume Algorithm (2008)
Eurographics E. Gröller, L. Szirmay-kalos, Jaakko Lehtinen, Samuli Laine, Timo Aila
We identify and analyze several performance problems in a state-of-the-art physically-based soft shadow volume algorithm, and present an improved method that alleviates these problems by replacing an...
Stroke pattern analysis and synthesis (2008)
Eurographics E. Gröller, L. Szirmay-kalos, Pascal Barla, Simon Breslav, Joëlle Thollot, François Sillion, ...
(Guest Editors) Abstract Splicing Upper-Body Actions with Locomotion (2008)
Eurographics E. Gröller, L. Szirmay-kalos, Rachel Heck, Lucas Kovar, Michael Gleicher
This paper presents a simple and efficient technique for synthesizing high-fidelity motions by attaching, or splicing, the upper-body action of one motion example to the lower-body locomotion of...
Eurographics E. Gröller, L. Szirmay-kalos, C. Walder, B. Schölkopf, O. Chapelle
We consider the problem of constructing a globally smooth analytic function that represents a surface implicitly by way of its zero set, given sample points with surface normal vectors. The...
(Guest Editors) Abstract Semantic Photo Synthesis (2008)
Eurographics E. Gröller, L. Szirmay-kalos, M. Johnson, G. J. Brostow, J. Shotton, O. Ar, ...
Composite images are synthesized from existing photographs by artists who make concept art, e.g., storyboards for movies or architectural planning. Current techniques allow an artist to fabricate...
Bounded Radiosity-- Illumination on General Surfaces and Clusters (2007)
Eurographics D. Fellner, L. Szirmay-kalos, Marc Stamminger, Hans-peter Seidel
Traditionally, Radiosity algorithms have been restricted to scenes made from planar patches. Most algorithms for computing form factors and the subdivision criterion for hierarchical methods...
Efficient Impostor Manipulation for Real-Time Visualization of Urban Scenery (2007)
Eurographics D. Fellner, L. Szirmay-kalos, Francois Sillion, George Drettakis, Benoit Bodelet
Urban environments present unique challenges to interactive visualization systems, because of the huge complexity of the geometrical data and the widely varying visibility conditions. This paper...
Implicit Surface Modelling with a Globally Regularised Basis of Compact Support (2006)
Walder, Christian, Schoelkopf, Bernhard, Chapelle, Olivier, Groller, E., Szirmay-Kalos, L.
We consider the problem of constructing a globally smooth analytic function that represents a surface implicitly by way of its zero set, given sample points with surface normal vectors. The...
