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 ... -
Acquisition and Rendering of Transparent and Refractive Objects
(The Eurographics Association, 2002)This paper introduces a new image-based approach to capturing and modeling highly specular, transparent, or translucent objects. We have built a system for automatically acquiring high quality graphical models of objects ... -
Appearance based object modeling using texture database: Acquisition, compression and rendering
(The Eurographics Association, 2002)Image-based object modeling can be used to compose photorealistic images of modeled objects for various rendering conditions, such as viewpoint, light directions, etc. However, it is challenging to acquire the large number ... -
Approximate Soft Shadows on Arbitrary Surfaces using PenumbraWedges
(The Eurographics Association, 2002)Shadow generation has been subject to serious investigation in computer graphics, and many clever algorithms have been suggested. However, previous algorithms cannot render high quality soft shadows onto arbitrary, animated ... -
Curve Analogies
(The Eurographics Association, 2002)This paper describes a method for learning statistical models of 2D curves, and shows how these models can be used to design line art rendering styles by example. A user can create a new style by providing an example of ... -
Efficient High Quality Rendering of Point Sampled Geometry
(The Eurographics Association, 2002)We propose a highly efficient hierarchical representation for point sampled geometry that automatically balances sampling density and point coordinate quantization. The representation is very compact with a memory consumption ... -
Enhancing and Optimizing the Render Cache
(The Eurographics Association, 2002)Interactive rendering often requires the use of simplified shading algorithms with reduced illumination fidelity. Higher quality rendering algorithms are usually too slow for interactive use. The render cache is a technique ... -
Exact From-Region Visibility Culling
(The Eurographics Association, 2002)To pre-process a scene for the purpose of visibility culling during walkthroughs it is necessary to solve visibility from all the elements of a finite partition of viewpoint space. Many conservative and approximate solutions ... -
Fast Primitive Distribution for Illustration
(The Eurographics Association, 2002)In this paper we present a high-quality, image-space approach to illustration that preserves continuous tone by probabilistically distributing primitives while maintaining interactive rates. Our method allows for frame-to-frame ... -
Fast, Arbitrary BRDF Shading for Low-Frequency Lighting Using Spherical Harmonics
(The Eurographics Association, 2002)Real-time shading using general (e.g., anisotropic) BRDFs has so far been limited to a few point or directional light sources. We extend such shading to smooth, area lighting using a low-order spherical harmonic basis for ... -
The Free-form Light Stage
(The Eurographics Association, 2002)We present the Free-form Light Stage, a system that captures the reflectance field of an object using a free-moving, hand-held light source. By photographing the object under different illumination conditions, we are able ... -
GigaWalk: Interactive Walkthrough of Complex Environments
(The Eurographics Association, 2002)We present a new parallel algorithm and a system, GigaWalk, for interactive walkthrough of complex, gigabytesized environments. Our approach combines occlusion culling and levels-of-detail and uses two graphics pipelines ... -
Hardware-Accelerated Point-Based Rendering of Complex Scenes
(The Eurographics Association, 2002)High quality point rendering methods have been developed in the last years. A common drawback of these approaches is the lack of hardware support. We propose a novel point rendering technique that yields good image quality ... -
Image-based Environment Matting
(The Eurographics Association, 2002)Environment matting is a powerful technique for modeling the complex light-transport properties of real-world optically active elements: transparent, refractive and reflective objects. Recent research has shown how environment ... -
Interactive Global Illumination using Fast Ray Tracing
(The Eurographics Association, 2002)Rasterization hardware provides interactive frame rates for rendering dynamic scenes, but lacks the ability of ray tracing required for efficient global illumination simulation. Existing ray tracing based methods yield ... -
Interactive Global Illumination Using Selective Photon Tracing
(The Eurographics Association, 2002)We present a method for interactive global illumination computation which is embedded in the framework of Quasi-Monte Carlo photon tracing and density estimation techniques. The method exploits temporal coherence of ... -
Local Illumination Environments for Direct Lighting Acceleration
(The Eurographics Association, 2002)Computing high-quality direct illumination in scenes with many lights is an open area of research. This paper presents a world-space caching mechanism called local illumination environments that enables interactive direct ... -
Microfacet Billboarding
(The Eurographics Association, 2002)Rendering of intricately shaped objects that are soft or cluttered is difficult because we cannot accurately acquire their complete geometry. Since their geometry varies drastically, modeling them using fixed facets can ... -
Picture Perfect RGB Rendering Using Spectral Prefiltering and Sharp Color Primaries
(The Eurographics Association, 2002)Accurate color rendering requires the consideration of many samples over the visible spectrum, and advanced rendering tools developed by the research community offer multispectral sampling towards this goal. However, for ... -
A Real-Time Distributed Light Field Camera
(The Eurographics Association, 2002)We present the design and implementation of a real-time, distributed light field camera. Our system allows multiple viewers to navigate virtual cameras in a dynamically changing light field that is captured in real-time. ...
