Mixing Fluids and Granular Materials
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Fluid animations in computer graphics show interactions with various kinds of objects. However, fluid flowing through a granular material such as sand is still not possible within current frameworks. In this paper, we ... -
Modal Locomotion: Animating Virtual Characters with Natural Vibrations
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a general method to intuitively create a wide range of locomotion controllers for 3D legged characters. The key of our approach is the assumption that efficient locomotion can exploit the natural vibration modes ... -
Motion Compression using Principal Geodesics Analysis
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Due to the growing need for large quantities of human animation data in the entertainment industry, it has become a necessity to compress motion capture sequences in order to ease their storage and transmission. We present ... -
Out-of-core Data Management for Path Tracing on Hybrid Resources
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a software system that enables path-traced rendering of complex scenes. The system consists of two primary components: an application layer that implements the basic rendering algorithm, and an out-of-core ... -
A Part-aware Surface Metric for Shape Analysis
(The Eurographics Association and Blackwell Publishing Ltd, 2009)The notion of parts in a shape plays an important role in many geometry problems, including segmentation, correspondence, recognition, editing, and animation. As the fundamental geometric representation of 3D objects in ... -
Physically Guided Animation of Trees
(The Eurographics Association and Blackwell Publishing Ltd, 2009)This paper presents a new method to animate the interaction of a tree with wind both realistically and in real time. The main idea is to combine statistical observations with physical properties in two major parts of tree ... -
Physics-driven Multi Dimensional Keyframe Animation for Artist-directable Interactive Character
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Various forms of art and entertainment involve many different characters, and advances in human interfaces have necessitated physical interactions in order to develop an improved sense of reality. In this paper we propose ... -
Positional, Metric, and Curvature Control for Constraint-Based Surface Deformation
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a geometry processing framework that allows direct manipulation or preservation of positional, metric, and curvature constraints anywhere on the surface of a geometric model. Target values for these properties ... -
Predicting Display Visibility Under Dynamically Changing Lighting Conditions
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Display devices, more than ever, are finding their ways into electronic consumer goods as a result of recent trends in providing more functionality and user interaction. Combined with the new developments in display ... -
Range Scan Registration Using Reduced Deformable Models
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present an unsupervised method for registering range scans of deforming, articulated shapes. The key idea is to model the motion of the underlying object using a reduced deformable model. We use a linear skinning model ... -
Scalable real-time animation of rivers
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Many recent games and applications target the interactive exploration of realistic large scale worlds. These worlds consist mostly of static terrain models, as the simulation of animated fluids in these virtual worlds is ... -
Shadowing Dynamic Scenes with Arbitrary BRDFs
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a real-time relighting and shadowing method for dynamic scenes with varying lighting, view and BRDFs. Our approach is based on a compact representation of reflectance data that allows for changing the BRDF at ... -
Shape Decomposition using Modal Analysis
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We introduce a novel algorithm that decomposes a deformable shape into meaningful parts requiring only a single input pose. Using modal analysis, we are able to identify parts of the shape that tend to move rigidly. We ... -
Simplification of Articulated Meshes
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a method for simplifying a polygonal character with an associated skeletal deformation such that the simplified character approximates the original shape well when deformed. As input, we require a set of example ... -
Simulation of two-phase flow with sub-scale droplet and bubble effects
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a new Eulerian-Lagrangian method for physics-based simulation of fluid flow, which includes automatic generation of sub-scale spray and bubbles. The Marker Level Set method is used to provide a simple geometric ... -
Spectral-Based Group Formation Control
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Given a pair of keyframe formations for a group consisting of multiple individuals, we present a spectral-based approach to smoothly transforming a source group formation into a target formation while respecting the clusters ... -
A Statistical Model of Human Pose and Body Shape
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Generation and animation of realistic humans is an essential part of many projects in today s media industry. Especially, the games and special effects industry heavily depend on realistic human animation. In this work a ... -
Structure from silhouettes: a new paradigm for fast sketch-based design of trees
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Modeling natural elements such as trees in a plausible way, while offering simple and rapid user control, is a challenge. This paper presents a method based on a new structure from silhouettes paradigm. We claim that ... -
Structure-Preserving Reshape for Textured Architectural Scenes
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Modeling large architectural environments is a difficult task due to the intricate nature of these models and the complex dependencies between the structures represented. Moreover, textures are an essential part of ... -
Symmetry Detection Using Feature Lines
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In this paper, we describe a new algorithm for detecting structural redundancy in geometric data sets. Our algorithm computes rigid symmetries, i.e., subsets of a surface model that reoccur several times within the model ...
