Practical Real-Time Lens-Flare Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present a practical real-time approach for rendering lens-flare effects. While previous work employed costly ray tracing or complex polynomial expressions, we present a coarser, but also significantly faster solution. ... -
Temporally Coherent Adaptive Sampling for Imperfect Shadow Maps
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We propose a new adaptive algorithm for determining virtual point lights (VPL) in the scope of real-time instant radiosity methods, which use a limited number of VPLs. The proposed method is based on Metropolis-Hastings ... -

A Shape-Aware Model for Discrete Texture Synthesis
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present a novel shape-aware method for synthesizing 2D and 3D discrete element textures consisting of collections of distinct vector graphics objects. Extending the long-proven point process framework, we propose a shape ... -
Spherical Visibility Sampling
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Many 3D scenes (e.g. generated from CAD data) are composed of a multitude of objects that are nested in each other. A showroom, for instance, may contain multiple cars and every car has a gearbox with many gearwheels located ... -
A Topological Approach to Voxelization
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present a novel approach to voxelization, based on intersecting the input primitives against intersection targets in the voxel grid. Instead of relying on geometric proximity measures, our approach is topological in ... -
Automatic Cinemagraph Portraits
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Cinemagraphs are a popular new type of visual media that lie in-between photos and video; some parts of the frame are animated and loop seamlessly, while other parts of the frame remain completely still. Cinemagraphs are ... -
Probabilistic Visibility Evaluation for Direct Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2013)The efficient evaluation of visibility in a three-dimensional scene is a longstanding problem in computer graphics. Visibility evaluations come in many different forms: figuring out what object is visible in a pixel; ... -
Line-Sweep Ambient Obscurance
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Screen-space ambient occlusion and obscurance have become established methods for rendering global illumi- nation effects in real-time applications. While they have seen a steady line of refinements, their computational ... -
Photon Beam Diffusion: A Hybrid Monte Carlo Method for Subsurface Scattering
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present photon beam diffusion, an efficient numerical method for accurately rendering translucent materials. Our approach interprets incident light as a continuous beam of photons inside the material. Numerically ... -
Computational Simulation of Alternative Photographic Processes
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present a novel computational framework for physically and chemically-based simulations of analog alternative photographic processes. In the real world, these processes allow the creation of very personal and unique ... -
Optimizing Disparity for Motion in Depth
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Beyond the careful design of stereo acquisition equipment and rendering algorithms, disparity post-processing has recently received much attention, where one of the key tasks is to compress the originally large disparity ... -
Generating Pointillism Paintings Based on Seurat's Color Composition
(The Eurographics Association and Blackwell Publishing Ltd., 2013)This paper presents a novel example-based stippling technique that employs a simple and intuitive concept to convert a color image into a pointillism painting. Our method relies on analyzing and imitating the color ... -
Interactive Lighting Design with Hierarchical Light Representation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Lighting design plays a crucial role in indoor lighting design, computer cinematograph and many other applications. Computer-assisted lighting design aims to find a lighting configuration that best approximates the ... -
Sorted Deferred Shading for Production Path Tracing
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Ray-traced global illumination (GI) is becoming widespread in production rendering but incoherent secondary ray traversal limits practical rendering to scenes that fit in memory. Incoherent shading also leads to intractable ... -
An Area-Preserving Parametrization for Spherical Rectangles
(The Eurographics Association and Blackwell Publishing Ltd., 2013)We present an area-preserving parametrization for spherical rectangles which is an analytical function with domain in the unit rectangle [0;1]2 and range in a region included in the unit-radius sphere. The parametrization ... -
Exponential Soft Shadow Mapping
(The Eurographics Association and Blackwell Publishing Ltd., 2013)In this paper we present an image-based algorithm to render visually plausible anti-aliased soft shadows in real time. Our technique employs a new shadow pre-filtering method based on an extended exponential shadow mapping ... -
Factorized Point Based Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2013)The Point-Based Global Illumination (PBGI) algorithm is composed of two major steps: a caching step and a multiview rasterization step. At caching time, a dense point-sampling of the scene is shaded and organized in a ...
