Interactive Global Illumination in Complex and Highly Occluded Environments
(The Eurographics Association, 2003)Global illumination algorithms have traditionally been very time consuming and were only suitable for off-line computations. Recent research in realtime ray tracing has improved global illumination performance to allow for ... -
Interactive Rendering of Translucent Deformable Objects
(The Eurographics Association, 2003)Realistic rendering of materials such as milk, fruits, wax, marble, and so on, requires the simulation of subsurface scattering of light. This paper presents an algorithm for plausible reproduction of subsurface scattering ... -
Interactive Texture Synthesis on Surfaces Using Jump Maps
(The Eurographics Association, 2003)We introduce a new method for fast texture synthesis on surfaces from examples. We generalize the image-based jump map texture synthesis algorithm, which partitions the task of texture synthesis into a slower analysis phase ... -
Interactive Time-Dependent Tone Mapping Using Programmable Graphics Hardware
(The Eurographics Association, 2003)Modern graphics architectures have replaced stages of the graphics pipeline with fully programmable modules. Therefore, it is now possible to perform fairly general computation on each vertex or fragment in a scene. In ... -
A New Reconstruction Filter for Undersampled Light Fields
(The Eurographics Association, 2003)This paper builds on previous research in the light field area of image-based rendering. We present a new reconstruction filter that significantly reduces the "ghosting" artifacts seen in undersampled light fields, while ... -
Optimizing Color Matching in a Lighting Reproduction System for Complex Subject and Illuminant Spectra
(The Eurographics Association, 2003)This paper presents a technique for improving color matching results in an LED-based lighting reproduction system for complex light source spectra. In our technique, we use measurements of the spectral response curve of ... -
Path Integration for Light Transport in Volumes
(The Eurographics Association, 2003)Simulating the transport of light in volumes such as clouds or objects with subsurface scattering is computationally expensive. We describe an approximation to such transport using path integration. Unlike the more commonly ... -
Penumbra Maps: Approximate Soft Shadows in Real-Time
(The Eurographics Association, 2003)Generating soft shadows quickly is difficult. Few techniques have enough flexibility to interactively render soft shadows in scenes with arbitrarily complex occluders and receivers. This paper introduces the penumbra map, ... -
Rapid Shadow Generation in Real-World Lighting Environments
(The Eurographics Association, 2003)We propose a new algorithm that uses consumer-level graphics hardware to render shadows cast by synthetic objects and a real lighting environment. This has immediate benefit for interactive Augmented Reality applications, ... -
Recovering 3-D Shape and Reflectance From a Small Number of Photographs
(The Eurographics Association, 2003)There are computer graphics applications for which the shape and reflectance of complex objects, such as faces, cannot be obtained using specialized equipment due to cost and practical considerations. We present an imagebased ... -
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 ... -
Rendering Fake Soft Shadows with Smoothies
(The Eurographics Association, 2003)We present a new method for real-time rendering of shadows in dynamic scenes. Our approach builds on the shadow map algorithm by attaching geometric primitives that we call "smoothies" to the objects' silhouettes. The ... -
Rendering Time Estimation for Real-Time Rendering
(The Eurographics Association, 2003)This paper addresses the problem of estimating the rendering time for a real-time simulation. We study different factors that contribute to the rendering time in order to develop a framework for rendering time estimation. ... -
A Stained Glass Image Filter
(The Eurographics Association, 2003)Medieval stained glass windows are a stylized artform that has not previously been thoroughly treated in the computer graphics literature. In this paper, we present an automated method for transforming an arbitrary image ... -
Translucent Shadow Maps
(The Eurographics Association, 2003)Shadow maps are a very efficient means to add shadows to arbitrary scenes. In this paper, we introduce Translucent Shadow Maps, an extension to shadow maps which allows very efficient rendering of sub-surface scattering. ... -
The Trilateral Filter for High Contrast Images and Meshes
(The Eurographics Association, 2003)We present a new, single-pass nonlinear filter for edge-preserving smoothing and visual detail removal for N dimensional signals in computer graphics, image processing and computer vision applications. Built from two ... -
Visualization of woven cloth
(The Eurographics Association, 2003)A technique for visualizing clothes is proposed that can handle rendering of complex weave patterns. An industrial standard of weave representation is used to derive the weave pattern and a detailed model of light interaction ... -
Wavelet Environment Matting
(The Eurographics Association, 2003)In this paper we present a novel approach for capturing the environment matte of a scene. We impose no restrictions on material properties of the objects in the captured scene and exploit scene characteristics (e.g. material ...
