Optimal Source Selection in Shooting Random Walk Monte Carlo Radiosity
(Blackwell Publishers Ltd and the Eurographics Association, 1997)
In this paper we study how to optimally select between different sources in shooting random walk Monte Carlo Radiosity. Until now the probability of selecting a source has been made proportional to the importance of that ...
Variance Analysis of Multi-sample and One-sample Multiple Importance Sampling
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We reexamine in this paper the variance for the Multiple Importance Sampling (MIS) estimator for multi-sample and onesample model. As a result of our analysis we can obtain the optimal estimator for the multi-sample model ...
Interactive Volume Illustration Using Intensity Filtering
(The Eurographics Association, 2010)
We propose a simple and interactive technique for volume illustration by using the difference between the original intensity values and a low-pass filtered copy. This difference, known as unsharped mask, provides us with ...
GPUGI: Global Illumination Effects on the GPU
(The Eurographics Association, 2006)
In this tutorial we explain how global illumination rendering methods can be implemented on Shader Model 3.0 GPUs. These algorithms do not follow the conventional local illumination model of Di- rectX/OpenGL pipelines, but ...
Real-time Obscurances with Color Bleeding (the three cubes demo)
(Eurographics Association, 2003)
Here we present an animation that demonstrates the power of the obscurances technique and how it can be used in a video-game context when moving objects are in the scene. Obscurances is a powerful technique that simulates ...
Information Theory in Visualization
(The Eurographics Association, 2016)
In this half-day tutorial, we review a variety of applications of information theory in visualization. The holistic nature of information-theoretic reasoning has enabled many such applications, ranging from light placement ...
Leaf Cluster Impostors for Tree Rendering with Parallax
(The Eurographics Association, 2005)
This paper presents a simple method to render complex trees on high frame rates while maintaining parallax effects. Based on the recognition that a planar impostor is accurate if the represented polygon is in its plane, ...
A Pyramidal Hemisphere Subdivision Method for Monte Carlo Radiosity
(Eurographics Association, 1999)
In this paper we present a new method to improve Monte Carlo radiosity by sending more rays towards selected directions. More precisely, we determine regions of the scene where the distribution of the power must be done ...
Improving Shadow Map Filtering with Statistical Analysis
(The Eurographics Association, 2011)
Shadow maps are widely used in real-time applications. Shadow maps cannot be filtered linearly as regular textures, thus undersampling leads to severe aliasing. This problem has been attacked by methods that transform the ...
Applications of Information Theory to Computer Graphics
(The Eurographics Association, 2007)
We present different applications of information theory to computer graphics, based on the use of the measures of entropy, mutual information, f-divergences and generalized entropies. The application areas are hierarchical ...
