Light Field Rendering for Games
(The Eurographics Association, 2008)This paper studies the problem of integrating high-quality light field rendering into state-of-the-art real-time computer games. We present a complete production pipeline for generation of light fields from arbitrary complex ... -
Light Field Synthesis from a Single Image using Improved Wasserstein Generative Adversarial Network
(The Eurographics Association, 2018)We present a deep learning-based method to synthesize a 4D light field from a single 2D RGB image. We consider the light field synthesis problem equivalent to image super-resolution, and solve it by using the improved ... -
Light Field Techniques for Reflections and Refractions
(The Eurographics Association, 1999)Reflections and refractions are important visual effects that have long been considered too costly for interactive applications. Although most contemporary graphics hardware supports reflections off curved surfaces in the ... -
Light Field Video Compression and Real Time Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Light field imaging is rapidly becoming an established method for generating flexible image based description of scene appearances. Compared to classical 2D imaging techniques, the angular information included in light ... -
A Light Hierarchy for Fast Rendering of Scenes with Many Lights
(Blackwell Publishers Ltd and the Eurographics Association, 1998)We introduce a new data structure in the form of a light hierarchy for efficiently ray-tracing scenes with many light sources. An octree is constructed with the point light sources in a scene. Each node represents all the ... -
Light Montage for Perceptual Image Enhancement
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Recent photography techniques such as sculpting with light show great potential in compositing beautiful images from fixed-viewpoint photos under multiple illuminations. The process relies heavily on the artists experience ... -
Light Optimization for Detail Highlighting
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper we propose an effective technique for the automatic arrangement of spot lights and other luminaires on or near user-provided arbitrary mounting surfaces in order to highlight the geometric details of complex ... -
Light Propagation Maps on Parallel Graphics Architectures
(The Eurographics Association, 2012)Light going through a participating medium like smoke can be scattered or absorbed by every point in the medium. To accurately render such a medium we must compute the radiance resulting at every point inside the medium ... -
Light Source Detection in Photographs
(The Eurographics Association, 2009)Common tasks related to image processing or augmented reality include rendering new objects into existing images, or matching objects with unknown illumination. To facilitate such algorithms, it is often necessary to infer ... -
Light Space Perspective Shadow Maps
(The Eurographics Association, 2004)In this paper, we present a new shadow mapping technique that improves upon the quality of perspective and uniform shadow maps. Our technique uses a perspective transform specified in light space which allows treating all ... -
Light Waving: Estimating Light Positions From Photographs Alone
(The Eurographics Association and Blackwell Publishing, Inc, 2005) -
Light-Field DVR on GPU for Streaming Time-Varying Data
(The Eurographics Association, 2018)Direct Volume Rendering (DVR) of volume data can be a memory intensive task in terms of footprint and cache-coherency. Rayguided methods may not be the best option to interactively render to light-fields due to feedback ... -
Light-Field Retargeting
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a first approach to light-field retargeting using z-stack seam carving, which allows light-field compression and extension while retaining angular consistency. Our algorithm first converts an input light field ... -
Light-Guided Tree Modeling of Diverse Biomorphs
(The Eurographics Association, 2015)Creation of tree models faithful to light environment is an important task in computer graphics as well as in botanical research, such as horticulture and forestry. In this paper, we propose an approach to model virtual ... -
Lightcut Interpolation
(The Eurographics Association, 2016)Many-light rendering methods replace multi-bounce light transport with direct lighting from many virtual point light sources to allow for simple and efficient computation of global illumination. Lightcuts build a hierarchy ... -
Lighting and Occlusion in a Wave-Based Framework
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present novel methods to enhance Computer Generated Holography (CGH) by introducing a complex-valued wave-based occlusion handling method. This offers a very intuitive and efficient interface to introduce optical elements ... -
Lighting Design: A Goal Based Approach Using Optimisation
(The Eurographics Association, 1999)There is a need for reliable lighting design applications because available tools are limited and inappropriate for interactive or creative use. Architects and lighting designers need those applications to define, predict, ... -
Lighting Layout Optimization for 3D Indoor Scenes
(The Eurographics Association and John Wiley & Sons Ltd., 2019)As the number of models for 3D indoor scenes are increasing rapidly, methods for generating the lighting layout have also become increasingly important. This paper presents a novel method that creates optimal placements ... -
Lighting Simulation of Augmented Outdoor Scene Based on a Legacy Photograph
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We propose a novel approach to simulate the illumination of augmented outdoor scene based on a legacy photograph. Unlike previous works which only take surface radiosity or lighting related prior information as the basis ... -
Lighting-Up Geometry: Accurate 3D Modelling of Museum Artifacts with a Torch and a Camera
(The Eurographics Association, 2006)This paper addresses the problem of obtaining complete, very detailed reconstructions of shiny objects such as glazed ceramics. We present an algorithm which uses silhouettes of the object, as well as images obtained under ...
