Fast Ray Tracing of Arbitrary Implicit Surfaces with Interval and Affine Arithmetic
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Existing techniques for rendering arbitrary-form implicit surfaces are limited, either in performance, correctness or flexibility. Ray tracing algorithms employing interval arithmetic (IA) or affine arithmetic (AA) for ... -
A Psychophysical Evaluation of Inverse Tone Mapping Techniques
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In recent years inverse tone mapping techniques have been proposed for enhancing low-dynamic range (LDR) content for a high-dynamic range (HDR) experience on HDR displays, and for image based lighting. In this paper, we ... -
Compression of Human Motion Capture Data Using Motion Pattern Indexing
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In this work, a novel scheme is proposed to compress human motion capture data based on hierarchical structure construction and motion pattern indexing. For a given sequence of 3D motion capture data of human body, the 3D ... -
Efficient Geometry Compression for GPU-based Decoding in Realtime Terrain Rendering
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a geometry compression scheme for restricted quadtree meshes and use this scheme for the compression of adaptively triangulated digital elevation models (DEMs). A compression factor of 8-9 is achieved by employing ... -
BTF-CIELab: A Perceptual Difference Measure for Quality Assessment and Compression of BTFs
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Driven by the advances in lossy compression of bidirectional texture functions (BTFs), there is a growing need for reliable methods to numerically measure the visual quality of the various compressed representations. Based ... -
Tangential Distance Fields for Mesh Silhouette Problems
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We consider a tangent-space representation of surfaces that maps each point on a surface to the tangent plane of the surface at that point. Such representations are known to facilitate the solution of several visibility ... -
Animating Quadrupeds: Methods and Applications
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Films like Shrek, Madagascar, The Chronicles of Narnia and Charlotte s web all have something in common: realistic quadruped animations. While the animation of animals has been popular for a long time, the technical ... -

Resolution Independent NPR-Style 3D Line Textures
(The Eurographics Association and Blackwell Publishing Ltd, 2009)This work introduces a technique for interactive walk-throughs of non-photorealistically rendered (NPR) scenes using three-dimensional (3D) line primitives to define architectural features of the model, as well as indicate ... -
Partial 3D Shape Retrieval by Reeb Pattern Unfolding
(The Eurographics Association and Blackwell Publishing Ltd, 2009) -
Autostereoscopic Rendering of Multiple Light Fields
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Light fields were introduced a decade ago as a new high-dimensional graphics rendering model. However, they have not been thoroughly used because their applications are very specific and their storage requirements are too ... -
Procedural Arrangement of Furniture for Real-Time Walkthroughs
(The Eurographics Association and Blackwell Publishing Ltd, 2009)This paper presents a procedural approach to generate furniture arrangements for large virtual indoor scenes. The interiors of buildings in 3D city scenes are often omitted. Our solution creates rich furniture arrangements ... -
Interactive Pixel-Accurate Free Viewpoint Rendering from Images with Silhouette Aware Sampling
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present an integrated, fully GPU-based processing pipeline to interactively render new views of arbitrary scenes from calibrated but otherwise unstructured input views. In a two-step procedure, our method first generates ... -
Volumetric Billboards
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We introduce an image-based representation, called volumetric billboards, allowing for the real-time rendering of semi-transparent and visually complex objects arbitrarily distributed in a 3D scene. Our representation ... -
Material Space Texturing
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Many objects have patterns that vary in appearance at different surface locations. We say that these are differences in materials, and we present a material-space approach for interactively designing such textures. At the ... -
Editing Object Behaviour in Video Sequences
(The Eurographics Association and Blackwell Publishing Ltd, 2009)While there are various commercial-strength editing tools available today for still images, object-based manipulation of real-world video footage is still a challenging problem. In this system paper, we present a framework ... -

Filling N-Sided Regions by Quad Meshes for Subdivision Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Given an n-sided region bounded by a loop of n polylines, we present a general algorithm to fill such a region by a quad mesh suitable for a subdivision scheme. Typically, the approach consists of two phases: the topological ...
