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 ... -
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 ... -
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 ... -
Feature Preserving Point Set Surfaces based on Non-Linear Kernel Regression
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Moving least squares (MLS) is a very attractive tool to design effective meshless surface representations. However, as long as approximations are performed in a least square sense, the resulting definitions remain sensitive ... -
Interactive Geometric Simulation of 4D Cities
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a simulation system that can simulate a three-dimensional urban model over time. The main novelty of our approach is that we do not rely on land-use simulation on a regular grid, but instead build a complete and ... -
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 ... -
Arches: a Framework for Modeling Complex Terrains
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In this paper, we present a framework for representing complex terrains with such features as overhangs, arches and caves and including different materials such as sand and rocks. Our hybrid model combines a volumetric ... -
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 ... -
Genuinity Signatures: Designing Signatures for Verifying 3D Object Genuinity
(The Eurographics Association and Blackwell Publishing Ltd, 2009)3D computer graphics models and digitally-controlled manufacturing have come together to enable the design, visualization, simulation, and automated creation of complex 3D objects. In our work, we propose and implement a ... -
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 ... -
Wrinkling Captured Garments Using Space-Time Data-Driven Deformation
(The Eurographics Association and Blackwell Publishing Ltd, 2009)The presence of characteristic fine folds is important for modeling realistic looking virtual garments. While recent garment capture techniques are quite successful at capturing the low-frequency garment shape and motion ... -
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 ... -
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 ... -
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 ... -
Fast BVH Construction on GPUs
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present two novel parallel algorithms for rapidly constructing bounding volume hierarchies on manycore GPUs. The first uses a linear ordering derived from spatial Morton codes to build hierarchies extremely quickly and ... -
Fast GPU-based Adaptive Tessellation with CUDA
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Compact surface descriptions like higher-order surfaces are popular representations for both modeling and animation. However, for fast graphics-hardware-assisted rendering, they usually need to be converted to triangle ... -
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 ... -
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 ... -
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 ... -
An Analytical Solution to Single Scattering in Homogeneous Participating Media
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Despite their numerous applications, efficiently rendering participating media remains a challenging task due to the intricacy of the radiative transport equation. As they provide a generic means of solving a wide variety ...
