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 ...
A Programmable Graphics Processor based on Partial Stream Rewriting
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Current graphics processing units (GPU) typically offer only a limited number of programmable pipeline stages, whose usage, data flow and topology are mostly fixed. Although a more flexible, custom rendering pipeline can ...
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. ...
EnvyDepth: An Interface for Recovering Local Natural Illumination from Environment Maps
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
In this paper, we present EnvyDepth, an interface for recovering local illumination from a single HDR environment map. In EnvyDepth, the user quickly indicates strokes to mark regions of the environment map that should be ...
Garment Modeling from a Single Image
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Modeling of realistic garments is essential for online shopping and many other applications including virtual characters. Most of existing methods either require a multi-camera capture setup or a restricted mannequin pose. ...
View-Dependent Realtime Rendering of Procedural Facades with High Geometric Detail
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present an algorithm for realtime rendering of large-scale city models with procedurally generated facades. By using highly detailed assets like windows, doors, and decoration such city models can provide an extremely ...
Geometry-Aware Volume-of-Fluid Method
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present a new framework to simulate moving interfaces in viscous incompressible two phase flows. The goal is to achieve both conservation of the fluid volume and a detailed reconstruction of the fluid surface. To these ...
