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 ...

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)
Out-of-Core and Dynamic Programming for Data Distribution on a Volume Visualization Cluster
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Ray directed volume-rendering algorithms are well suited for parallel implementation in a distributed cluster environment. For distributed ray casting, the scene must be partitioned between nodes for good load balancing, ...
