Constrainable Multigrid for Cloth
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present a new technique which can handle both point and sliding constraints in the multigrid (MG) framework. Although the MG method can theoretically perform as fast as O(N), the development of a clothing simulator based ...
Enhancing Bayesian Estimators for Removing Camera Shake
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
The aim of removing camera shake is to estimate a sharp version x from a shaken image y when the blur kernel k is unknown. Recent research on this topic evolved through two paradigms called MAP(k) and MAP(x,k). MAP(k) only ...
Dynamic Comics for Hierarchical Abstraction of 3D Animation Data
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Image storyboards of films and videos are useful for quick browsing and automatic video processing. A common approach for producing image storyboards is to display a set of selected key-frames in temporal order, which has ...
Topology Aware Data-Driven Inverse Kinematics
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Creating realistic human movement is a time consuming and labour intensive task. The major difficulty is that the user has to edit individual joints while maintaining an overall realistic and collision free posture. Previous ...
Synthesizing Two-character Interactions by Merging Captured Interaction Samples with their Spacetime Relationships
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Existing synthesis methods for closely interacting virtual characters relied on user-specified constraints such as the reaching positions and the distance between body parts. In this paper, we present a novel method for ...
Robust Image Denoising Using a Virtual Flash Image for Monte Carlo Ray Tracing
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We propose an efficient and robust image-space denoising method for noisy images generated by Monte Carlo ray tracing methods. Our method is based on two new concepts: virtual flash images and homogeneous pixels. Inspired ...
Improving Memory Space Efficiency of Kd-tree for Real-time Ray Tracing
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Compared with its competitors such as the bounding volume hierarchy, a drawback of the kd-tree structure is that a large number of triangles are repeatedly duplicated during its construction, which often leads to inefficient, ...
Level-of-Detail Streaming and Rendering using Bidirectional Sparse Virtual Texture Functions
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Bidirectional Texture Functions (BTFs) are among the highest quality material representations available today and thus well suited whenever an exact reproduction of the appearance of a material or complete object is required. ...
Non‐Local Image Reconstruction for Efficient Computation of Synthetic Bidirectional Texture Functions
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Visual prototyping of materials is relevant for many computer graphics applications. A large amount of modelling flexibility can be obtained by directly rendering micro‐geometry. While this is possible in principle, it is ...
Massively Parallel Hierarchical Scene Processing with Applications in Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present a novel method for massively parallel hierarchical scene processing on the GPU, which is based on sequential decomposition of the given hierarchical algorithm into small functional blocks. The computation is ...
