Viewpoint Quality: Measures and Applications
(The Eurographics Association, 2005)
Several methods that use the notion of viewpoint quality have been recently introduced in different areas of computer graphics, such as scene understanding, exploration of virtual worlds, radiosity and global illumination, ...
Informational Dialogue with Van Gogh's Paintings
(The Eurographics Association, 2008)
From the pioneering work by Birkhoff, several measures have been proposed to quantify the aesthetic content of art. After Bense's application of information theory to Birkhoff's ideas, the concept of informational aesthetics ...
Accelerating Path Tracing by Re-Using Paths
(The Eurographics Association, 2002)
This paper describes a new acceleration technique for rendering algorithms like path tracing, that use so called gathering random walks. Usually in path tracing, each traced path is used in order to compute a contribution ...
Real-Time Multiple Scattering in Participating Media with Illumination Networks
(The Eurographics Association, 2005)
This paper proposes a real-time method to compute multiple scattering in non-homogeneous participating media having general phase functions. The volume represented by a particle system is supposed to be static, but the ...
Refinement Criteria Based on f-Divergences
(The Eurographics Association, 2003)
In several domains a refinement criterion is often needed to decide whether to go on or to stop sampling a signal. When the sampled values are homogeneous enough, we assume that they represent the signal fairly well and ...
Viewpoint Entropy: A New Tool for Obtaining Good Views of Molecules
(The Eurographics Association, 2002)
The computation of good viewpoints is important in several fields: computer graphics, removal of degeneracies in computational geometry, robotics, graph drawing, etc. However, in areas such as computer graphics there is ...
Aesthetic Appraisal of Art - from Eye Movements to Computers
(The Eurographics Association, 2009)
By looking at a work of art, an observer enters into a dialogue. In this work, we attempt to analyze this dialogue with both behavioral and computational tools. In two experiments, observers were asked to look at a large ...
An Information-Theoretic Ambient Occlusion
(The Eurographics Association, 2007)
Ambient occlusion is a powerful technique that mimics indirect global illumination at a fraction of the cost. In this paper, we introduce a new ambient occlusion technique based on information-theoretic concepts. A viewpoint ...
Point Sampling with Uniformly Distributed Lines
(The Eurographics Association, 2005)
In this paper we address the problem of extracting representative point samples from polygonal models. The goal of such a sampling algorithm is to find points that are evenly distributed. We propose star-discrepancy as a ...
