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 ... -
Complex Barycentric Coordinates with Applications to Planar Shape Deformation
(The Eurographics Association and Blackwell Publishing Ltd, 2009) -
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 ... -
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 ... -
Bidirectional Importance Sampling for Unstructured Direct Illumination
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Recent research in bidirectional importance sampling has focused primarily on structured illumination sources such as distant environment maps, while unstructured illumination has received little attention. In this paper, ... -
Wind projection basis for real-time animation of trees
(The Eurographics Association and Blackwell Publishing Ltd, 2009)This paper presents a real-time method to animate complex scenes of thousands of trees under a user-controllable wind load. Firstly, modal analysis is applied to extract the main modes of deformation from the mechanical ... -
Completion and Reconstruction with Primitive Shapes
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We consider the problem of reconstruction from incomplete point-clouds. To find a closed mesh the reconstruction is guided by a set of primitive shapes which has been detected on the input point-cloud (e.g. planes, cylinders ... -
Heightfield and spatially varying BRDF Reconstruction for Materials with Interreflections
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Photo-realistic reproduction of material appearance from images has widespread use in applications ranging from movies over advertising to virtual prototyping. A common approach to this task is to reconstruct the small ... -
Energy Aware Color Sets
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a design technique for colors with the purpose of lowering the energy consumption of the display device. Our approach is based on a screen space variant energy model. The result of our design is a set of ... -
Learning good views through intelligent galleries
(The Eurographics Association and Blackwell Publishing Ltd, 2009)The definition of a good view of a 3D scene is highly subjective and strongly depends on both the scene content and the 3D application. Usually, camera placement is performed directly by the user, and that task may be ... -
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 ... -
Linear Time Super-Helices
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Thin elastic rods such as cables, phone coils, tree branches, or hair, are common objects in the real world but computing their dynamics accurately remains challenging. The recent Super-Helix model, based on the discrete ... -
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 ... -
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 ... -
Table-based Alpha Compression
(The Eurographics Association and Blackwell Publishing Ltd, 2009) -
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 ... -
Temporal Glare: Real-Time Dynamic Simulation of the Scattering in the Human Eye
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Glare is a consequence of light scattered within the human eye when looking at bright light sources. This effect can be exploited for tone mapping since adding glare to the depiction of high-dynamic range (HDR) imagery on ... -
Importance Sampling Spherical Harmonics
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In this paper we present the first practical method for importance sampling functions represented as spherical harmonics (SH). Given a spherical probability density function (PDF) represented as a vector of SH coefficients, ... -
Adaptive Caustic Maps Using Deferred Shading
(The Eurographics Association and Blackwell Publishing Ltd, 2009) -
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 ...
