Approximate on-Surface Distance Computation using Quasi-Developable Charts
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
There is a vast number of applications that require distance field computation over triangular meshes. State-of-the-art algorithms have quadratic or sub-quadratic worst-case complexity, making them impractical for interactive ...
Affective Modelling: Profiling Geometrical Models with Human Emotional Responses
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
In this paper, a novel concept, Affective Modelling, is introduced to encapsulate the idea of creating 3D models based on the emotional responses that they may invoke. Research on perceptually-related issues in Computer ...
HPCCD: Hybrid Parallel Continuous Collision Detection using CPUs and GPUs
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
We present a novel, hybrid parallel continuous collision detection (HPCCD) method that exploits the availability of multi-core CPU and GPU architectures. HPCCD is based on a bounding volume hierarchy (BVH) and selectively ...
ProcDef: Local-to-global Deformation for Skeleton-free Character Animation
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Animations of characters with flexible bodies such as jellyfish, snails, and, hearts are difficult to design using traditional skeleton-based approaches. A standard approach is keyframing, but adjusting the shape of the ...
Linkless Octree Using Multi-Level Perfect Hashing
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
The standard C/C++ implementation of a spatial partitioning data structure, such as octree and quadtree, is often inefficient in terms of storage requirements particularly when the memory overhead for maintaining parent-to-child ...
An Intuitive Interface for Interactive High Quality Image-Based Modeling
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
We present the design of an interactive image-based modeling tool that enables a user to quickly generate detailed 3D models with texture from a set of calibrated input images. Our main contribution is an intuitive user ...
Optimizing Structure Preserving Embedded Deformation for Resizing Images and Vector Art
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Smart deformation and warping tools play an important part in modern day geometric modeling systems. They allow existing content to be stretched or scaled while preserving visually salient information. To date, these ...
A Shape-Preserving Approach to Image Resizing
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
We present a novel image resizing method which attempts to ensure that important local regions undergo a geometric similarity transformation, and at the same time, to preserve image edge structure. To accomplish this, we ...
Fast, Sub-pixel Antialiased Shadow Maps
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Solving aliasing artifacts is an essential problem in shadow mapping approaches. Many works have been proposed, however, most of them focused on removing the texel-level aliasing that results from the limited resolution ...
Texture Splicing
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
We propose a new texture editing operation called texture splicing. For this operation, we regard a texture as having repetitive elements (textons) seamlessly distributed in a particular pattern. Taking two textures as ...
