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 ... -
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 ... -
Frontmatter
(The Eurographics Association and Blackwell Publishing Ltd, 2009) -
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 ... -
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 ... -
Hydraulic Erosion Using Smoothed Particle Hydrodynamics
(The Eurographics Association and Blackwell Publishing Ltd, 2009)This paper presents a new technique for modification of 3D terrains by hydraulic erosion. It efficiently couples fluid simulation using a Lagrangian approach, namely the Smoothed Particle Hydrodynamics (SPH) method, and a ... -
Image Appearance Exploration by Model-Based Navigation
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Changing the appearance of an image can be a complex and non-intuitive task. Many times the target image colors and look are only known vaguely and many trials are needed to reach the desired results. Moreover, the effect ... -
Implicit Contact Handling for Deformable Objects
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present an algorithm for robust and efficient contact handling of deformable objects. By being aware of the internal dynamics of the colliding objects, our algorithm provides smooth rolling and sliding, stable stacking, ... -
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, ... -
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 ... -
Into the Blue: Better Caustics through Photon Relaxation
(The Eurographics Association and Blackwell Publishing Ltd, 2009)The photon mapping method is one of the most popular algorithms employed in computer graphics today. However, obtaining good results is dependent on several variables including kernel shape and bandwidth, as well as the ... -
LazyBrush: Flexible Painting Tool for Hand-drawn Cartoons
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In this paper we present LazyBrush, a novel interactive tool for painting hand-made cartoon drawings and animations. Its key advantage is simplicity and flexibility. As opposed to previous custom tailored approaches [SBv05, ... -
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 ... -
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 ... -
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 ...
