  Rendering of large, detailed 3D terrains on commodity hardware has become possible through the use of raycasting, data caching and prefetching. Adding dynamic shadows as they appear during a day-night cycle remais a challenge ...

• Pixel Merge Unit 

  Sathe, Rahul; Akenine-Möller, Tomas (The Eurographics Association, 2015)

  Multi-sample anti-aliasing is a popular technique for reducing geometric aliasing (jagged edges) and is supported in all modern graphics processors. With multi-sampling anti-aliasing, visibility and depth are sampled more ...

• An Interactive Editing System for Visual Appearances of Fire and Explosions 

  Dobashi, Yoshinori; Shibukawa, Yuhei; Tada, Munehiro; Sato, Syuhei; Iwasaki, Kei; Yamamoto, Tsuyoshi (The Eurographics Association, 2015)

  Synthetic volumetric fire and explosions are important visual effects used in many applications such as computer games and movies. For these applications, artists are often requested to achieve the desired visual appearance ...

• Target Temperature Driven Dynamic Flame Animation 

  Cui, Qiaodong; Wu, Zhaohui; Xing, Chang; Zhou, Zhong; Wu, Wei (The Eurographics Association, 2015)

  Fire/flame plays an important role in virtual environment. Controlling the flame behavior in an intuitive yet precise manner remains a challenging open problem. In this paper, a target temperature driven simulation method ...

• Individual Time Stepping for SPH Fluids 

  He, Liangliang; Ban, Xiaojuan; Liu, Xu; Wang, Xiaokun (The Eurographics Association, 2015)

  We present a novel adaptive stepping scheme for SPH fluids, in which particles have their own time-steps determined from local conditions, e.g. Courant condition. These individual time-steps are constrained for global ...

• Eye-tracktive: Measuring Attention to Body Parts when Judging Human Motions 

  Ennis, Cathy; Hoyet, Ludovic; O'Sullivan, Carol (The Eurographics Association, 2015)

  Virtual humans are often endowed with human-like characteristics to make them more appealing and engaging. Motion capture is a reliable way to represent natural motion on such characters, thereby allowing a wide range of ...

• Interactive HDR Environment Map Capturing on Mobile Devices 

  Kán, Peter (The Eurographics Association, 2015)

  Real world illumination, captured by digitizing devices, is beneficial to solve many problems in computer graphics. Therefore, practical methods for capturing this illumination are of high interest. In this paper, we present ...

• Sketch-Based Controllers for Blendshape Facial Animation 

  Cetinaslan, Ozan; Orvalho, Verónica; Lewis, John (The Eurographics Association, 2015)

  The blendshape approach is a widely used technique to generate realistic facial animation. However, creating blendshape facial animations using traditional weight editing tools requires either memorizing the function of a ...

• Content-Aware Projection for Tiny Planets 

  Brown, Matthew (The Eurographics Association, 2015)

  Tiny Planets visualise the world looking down at the ground, with physically unrealisable projections that curve the ground plane to look like small worlds. Whilst certain geometries, such as Stereographic, are known to ...

• Fractured Object Reassembly via Robust Surface Registration 

  Mavridis, Pavlos; Andreadis, Anthousis; Papaioannou, Georgios (The Eurographics Association, 2015)

  The reassembly of fractured 3D objects from their parts is an important problem in cultural heritage and other domains.We approach reassembly from a geometric matching perspective and propose a pipeline for the automatic ...

• Quadratic Encoding for Hand Pose Reconstruction from Multi-Touch Input 

  Chung, Se-Joon; Kim, Junggon; Han, Shangchen; Pollard, Nancy S. (The Eurographics Association, 2015)

  One of the most compelling challenges in virtual reality today is to allow users to carry out virtual manipulation tasks using their hands. Multi-touch devices are an interesting interface for this task, as they are widely ...

• Isogeometric Analysis for Modelling and Design 

  Riffnaller-Schiefer, Andreas; Augsdörfer, Ursula H.; Fellner, Dieter W. (The Eurographics Association, 2015)
