Multi-layered Indirect Texturing for Tree Rendering
(The Eurographics Association, 2007)
This paper presents a technique to render in real time complex trees using billboard clouds as an impostor simplification for the original polygonal tree, combined with a new texture-based representation for the foliage. ...
Conceptualizing Birkhoff's Aesthetic Measure Using Shannon Entropy and Kolmogorov Complexity
(The Eurographics Association, 2007)
In 1928, George D. Birkhoff introduced the Aesthetic Measure, defined as the ratio between order and complexity, and, in 1965, Max Bense analyzed Birkhoff s measure from an information theory point of view. In this paper, ...
Fast Visualisation and Interactive Design of Deterministic Fractals
(The Eurographics Association, 2008)
This paper describes an interactive software tool for the visualisation and the design of artistic fractal images. The software (called AttractOrAnalyst) implements a fast algorithm for the visualisation of basins of ...
Benford's Law for Natural and Synthetic Images
(The Eurographics Association, 2005)
Benford's Law (also known as the First Digit Law) is well known in statistics of natural phenomena. It states that, when dealing with quantities obtained from Nature, the frequency of appearance of each digit in the first ...
An Information-Theoretic Framework for Image Complexity
(The Eurographics Association, 2005)
In this paper, we introduce a new information-theoretic approach to study the complexity of an image. The new framework we present here is based on considering the information channel that goes from the histogram to the ...
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 ...
