Two Stage Importance Sampling for Direct Lighting
(The Eurographics Association, 2006)We describe an importance sampling method to generate samples based on the product of a BRDF and an environment map or large light source. The method works by creating a hierarchical partition of the light source based on ... -
Antialiasing for Automultiscopic 3D Displays
(The Eurographics Association, 2006)Automultiscopic displays show stereoscopic images that can be viewed from any viewpoint without special glasses. They hold great promise for the future of television and digital entertainment. However, the image quality ... -
Automatic Multiperspective Images
(The Eurographics Association, 2006)Multiperspective images generated from a collection of photographs or a videostream can be used to effectively summarize long, roughly planar scenes such as city streets. The final image will span a larger field of view ... -
An Efficient Multi-View Rasterization Architecture
(The Eurographics Association, 2006)TV have been designed and built. However, these displays have received relatively little attention in the context of real-time computer graphics. We present a novel rasterization architecture that rasterizes each triangle ... -
Tomographic Reconstruction of Transparent Objects
(The Eurographics Association, 2006)The scanning of 3D geometry has become a popular way of capturing the shape of real-world objects. Transparent objects, however, pose problems for traditional scanning methods. We present a visible light tomographic ... -
Sparse Lumigraph Relighting by Illumination and Reflectance Estimation from Multi-View Images
(The Eurographics Association, 2006)We present a novel relighting approach that does not assume that the illumination is known or controllable. Instead, we estimate the illumination and texture from given multi-view images captured under a single illumination ... -
Statistical Acquisition of Texture Appearance
(The Eurographics Association, 2006)We propose a simple method to acquire and reconstruct material appearance with sparsely sampled data. Our technique renders elaborate view- and light-dependent effects and faithfully reproduces materials such as fabrics ... -
Reconstruction of Volumetric Surface Textures for Real-Time Rendering
(The Eurographics Association, 2006)Volumetric texturing is a popular technique for rendering rich 3-D detail when a polygonal surface representation would be ineffective. Although efficient algorithms for rendering volumetric textures have been known for ... -
Handheld Pixels
(The Eurographics Association, 2006)During this decade, pixels have become mobile. Cell phones, PDAs, handheld gaming consoles and other similar devices start to have color displays by standard and color displays are hungry for high-quality graphics. QVGA ... -
Visual Chatter in the Real World
(The Eurographics Association, 2006)When a scene is lit by a source of light, the radiance of each point in the scene can be viewed as having two components, namely, direct and global. Recently, an efFIcient separation method has been proposed that uses high ... -
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 ... -
Non-linear Volume Photon Mapping
(The Eurographics Association, 2005)This paper describes a novel extension of the photon mapping algorithm, capable of handling both volume multiple inelastic scattering and curved light paths simultaneously. The extension is based on the Full Radiative ... -
A Hybrid Monte Carlo Method for Accurate and Efficient Subsurface Scattering
(The Eurographics Association, 2005)Subsurface scattering is a fundamental aspect of surface appearance responsible for the characteristic look of many materials. Monte Carlo path tracing techniques can be employed with high accuracy to simulate the scattering ... -
Adaptive Frameless Rendering
(The Eurographics Association, 2005)We propose an adaptive form of frameless rendering with the potential to dramatically increase rendering speed over conventional interactive rendering approaches. Without the rigid sampling patterns of framed renderers, ... -
Reflectance Sharing: Image-based Rendering from a Sparse Set of Images
(The Eurographics Association, 2005)When the shape of an object is known, its appearance is determined by the spatially-varying reflectance function defined on its surface. Image-based rendering methods that use geometry seek to estimate this function from ... -
Real Illumination from Virtual Environments
(The Eurographics Association, 2005)We introduce a method for actively controlling the illumination in a room so that it is consistent with a virtual world. In combination with a high dynamic range display, the system produces both uniform and directional ... -
Perceptually Based Tone Mapping of High Dynamic Range Image Streams
(The Eurographics Association, 2005)This paper presents a new perceptually based tone mapping operator that represents scene visibility under timevarying, high dynamic range conditions. The operator is based on a new generalized threshold model that extends ... -
Fast Exact From-Region Visibility in Urban Scenes
(The Eurographics Association, 2005)We present a fast exact from-region visibility algorithm for 2.5D urban scenes. The algorithm uses a subdivision of line space for identifying visibility interactions in a 2D footprint of the scene. Visibility in the ... -
A Low Dimensional Framework for Exact Polygon-to-Polygon Occlusion Queries
(The Eurographics Association, 2005)Despite the importance of from-region visibility computation in computer graphics, efficient analytic methods are still lacking in the general 3D case. Recently, different algorithms have appeared that maintain occlusion ... -
Colorization by Example
(The Eurographics Association, 2005)We present a new method for colorizing grayscale images by transferring color from a segmented example image. Rather than relying on a series of independent pixel-level decisions, we develop a new strategy that attempts ...
