Langevin Particle: A Self-Adaptive Lagrangian Primitive for Flow Simulation Enhancement
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We develop a new Lagrangian primitive, named Langevin particle, to incorporate turbulent flow details in fluid simulation. A group of the particles are distributed inside the simulation domain based on a turbulence energy ... -
Comprehensive Facial Performance Capture
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a system for recording a live dynamic facial performance, capturing highly detailed geometry and spatially varying diffuse and specular reflectance information for each frame of the performance. The result is a ... -
Scalable Remote Rendering with Depth and Motion-flow Augmented Streaming
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In this paper, we focus on efficient compression and streaming of frames rendered from a dynamic 3D model. Remote rendering and on-the-fly streaming become increasingly attractive for interactive applications. Data is kept ... -
Freehand HDR Imaging of Moving Scenes with Simultaneous Resolution Enhancement
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Despite their high popularity, common high dynamic range (HDR) methods are still limited in their practical applicability: They assume that the input images are perfectly aligned, which is often violated in practise. Our ... -
Wavelet Rasterization
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a method for analytically calculating an anti-aliased rasterization of arbitrary polygons or fonts bounded by Bezier curves in 2D as well as oriented triangle meshes in 3D. Our algorithm rasterizes multiple ... -
Contouring Discrete Indicator Functions
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a method for calculating the boundary of objects from Discrete Indicator Functions that store 2- material volume fractions with a high degree of accuracy. Although Marching Cubes and its derivatives are effective ... -
Discovery of Intrinsic Primitives on Triangle Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The discovery of meaningful parts of a shape is required for many geometry processing applications, such as parameterization, shape correspondence, and animation. It is natural to consider primitives such as spheres, ... -
SQuad: Compact Representation for Triangle Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The SQuad data structure represents the connectivity of a triangle mesh by its "S table" of about 2 rpt (integer references per triangle). Yet it allows for a simple implementation of expected constant-time, random-access ... -
Global Structure Optimization of Quadrilateral Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We introduce a fully automatic algorithm which optimizes the high-level structure of a given quadrilateral mesh to achieve a coarser quadrangular base complex. Such a topological optimization is highly desirable, since ... -
Interactive Modeling of City Layouts using Layers of Procedural Content
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In this paper, we present new solutions for the interactive modeling of city layouts that combine the power of procedural modeling with the flexibility of manual modeling. Procedural modeling enables us to quickly generate ... -
Procedural Modeling of Interconnected Structures
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The complexity and detail of geometric scenes that are used in today's computer animated films and interactive games have reached a level where the manual creation by traditional 3D modeling tools has become infeasible. ... -
Guided ProceduralModeling
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Procedural methods present one of the most powerful techniques for authoring a vast variety of computer graphics models. However, their massive applicability is hindered by the lack of control and a low predictability of ... -
Combinatorial Bidirectional Path-Tracing for Efficient Hybrid CPU/GPU Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents a reformulation of bidirectional path-tracing that adequately divides the algorithm into processes efficiently executed in parallel on both the CPU and the GPU. We thus benefit from high-level optimization ... -
Two-Level Grids for Ray Tracing on GPUs
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We investigate the use of two-level nested grids as acceleration structure for ray tracing of dynamic scenes. We propose a massively parallel, sort-based construction algorithm and show that the two-level grid is one of ... -
RTSAH Traversal Order for Occlusion Rays
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We accelerate the finding of occluders in tree based acceleration structures, such as a packetized BVH and a single ray kd-tree, by deriving the ray termination surface area heuristic (RTSAH) cost model for traversing an ... -
Symmetry Hierarchy of Man-Made Objects
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We introduce symmetry hierarchy of man-made objects, a high-level structural representation of a 3D model providing a symmetry-induced, hierarchical organization of the model's constituent parts. Given an input mesh, we ... -
Shape Analysis with Subspace Symmetries
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We address the problem of partial symmetry detection, i.e., the identification of building blocks a complex shape is composed of. Previous techniques identify parts that relate to each other by simple rigid mappings, ... -
Learning Line Features in 3D Geometry
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Feature detection in geometric datasets is a fundamental tool for solving shape matching problems such as partial symmetry detection. Traditional techniques usually employ a priori models such as crease lines that are ... -
Fruit Senescence and Decay Simulation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Aging and imperfections provide important visual cues for realism. We present a novel physically-based approach for simulating the biological aging and decay process in fruits. This method simulates interactions between ... -
Generalized Helicoids for Modeling Hair Geometry
(The Eurographics Association and Blackwell Publishing Ltd., 2011)In computer graphics, modeling the geometry of hair and hair-like patterns such as grass and fur remains a significant challenge. Hair strands can exist in an extensive variety of arrangements and the choice of an appropriate ...
