A Stylized Approach for Pencil Drawing from Photographs
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a stylized scheme that produces pencil drawings in a range of styles from an image. To produce controllable pencil drawing effects and remedy the problems of existing convolution-based schemes, we develop a swing ... -
Tessellation-Independent Smooth Shadow Boundaries
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We propose an efficient and light-weight solution for rendering smooth shadow boundaries that do not reveal the tessellation of the shadow-casting geometry. Our algorithm reconstructs the smooth contours of the underlying ... -
Parameterization-Aware MIP-Mapping
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a method of generating mipmaps that takes into account the distortions due to the parameterization of a surface. Existing algorithms for generating mipmaps assume that the texture is isometrically mapped to the ... -
Geometry Presorting for Implicit Object Space Partitioning
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a new data structure for object space partitioning that can be represented completely implicitly. The bounds of each node in the tree structure are recreated at run-time from the scene objects contained therein. ... -
Matting and Compositing for Fresnel Reflection on Wavy Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2012)This paper introduces a framework that can extract an alpha matte from a single image with Fresnel reflection, and that can composite other objects with the image such that plausible reflections are included. Our method ... -
Artistic Illumination Transfer for Portraits
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Relighting a portrait in a single image is still a challenging problem, particularly when only a single artistic reference photograph or painting is provided. In this paper, we propose an artistic illumination transfer ... -
Intrinsic Images by Clustering
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Decomposing an input image into its intrinsic shading and reflectance components is a long-standing ill-posed problem. We present a novel algorithm that requires no user strokes and works on a single image. Based on simple ... -
Progressive Virtual Beam Lights
(The Eurographics Association and Blackwell Publishing Ltd., 2012)A recent technique that forms virtual ray lights (VRLs) from path segments in media, reduces the artifacts common to VPL approaches in participating media, however, distracting singularities still remain. We present Virtual ... -
Quantized Point-Based Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Point-based global illumination (PBGI) uses a dense point sampling of the scene's surfaces to approximate indirect light transport and is intensively used in 3D motion pictures and special effects. Each point caches the ... -
Pre-convolved Radiance Caching
(The Eurographics Association and Blackwell Publishing Ltd., 2012)The incident indirect light over a range of image pixels is often coherent. Two common approaches to exploit this inter-pixel coherence to improve rendering performance are Irradiance Caching and Radiance Caching. Both ... -
Per-Vertex Defocus Blur for Stochastic Rasterization
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present user-controllable and plausible defocus blur for a stochastic rasterizer. We modify circle of confusion coefficients per vertex to express more general defocus blur, and show how the method can be applied to ... -
Polynomial Optics: A Construction Kit for Efficient Ray-Tracing of Lens Systems
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Simulation of light transport through lens systems plays an important role in graphics. While basic imaging properties can be conveniently derived from linear models (like ABCD matrices), these approximations fail to ... -
Preface and Table of Contents

Guided Image Filtering for Interactive High-quality Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Interactive computation of global illumination is a major challenge in current computer graphics research. Global illumination heavily affects the visual quality of generated images. It is therefore a key attribute for the ... -
Coherent Out-of-Core Point-Based Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We describe a new technique for coherent out-of-core point-based global illumination and ambient occlusion. Point-based global illumination (PBGI) is used in production to render tremendously complex scenes, so in-core ... -
A Ray Tracing Approach to Diffusion Curves
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Diffusion curves [OBW*08] provide a flexible tool to create smooth-shaded images from curves defined with colors. The resulting image is typically computed by solving a Poisson equation that diffuses the curve colors to ... -
Direct Ray Tracing of Phong Tessellation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)There are two major ways of calculating ray and parametric surface intersections in rendering. The first is through the use of tessellated triangles, and the second is to use parametric surfaces together with numerical ... -
Importance Point Projection for GPU-based Final Gathering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a practical importance-driven method for GPU-based final gathering. We take as input a point cloud representing directly illuminated scene geometry; we then project and splat the points to microbuffers, which ... -
Least Squares Vertex Baking
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We investigate the representation of signals defined on triangle meshes using linearly interpolated vertex attributes. Compared to texture mapping, storing data only at vertices yields significantly lower memory overhead ... -
Efficient Packing of Arbitrarily Shaped Charts for Automatic Texture Atlas Generation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Texture atlases are commonly used as representations for mesh parameterizations in numerous applications including texture and normal mapping. Therefore, packing is an important post-processing step that tries to place and ...
