Factored Facade Acquisition using Symmetric Line Arrangements
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce a novel framework for image-based 3D reconstruction of urban buildings based on symmetry priors. Starting from image-level edges, we generate a sparse and approximate set of consistent 3D lines. These lines ... -
Fast and Robust Normal Estimation for Point Clouds with Sharp Features
(The Eurographics Association and Blackwell Publishing Ltd., 2012)This paper presents a new method for estimating normals on unorganized point clouds that preserves sharp features. It is based on a robust version of the Randomized Hough Transform (RHT). We consider the filled Hough ... -
Fast Generation of Approximate Blue Noise Point Sets
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Poisson-disk sampling is a popular sampling method because of its blue noise power spectrum, but generation of these samples is computationally very expensive. In this paper, we propose an efficient method for fast generation ... -
Fast Grasp Synthesis for Various Shaped Objects
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Human-like grasp planning is difficult because a human hand has a high number of degrees of freedom, and there are many grasping styles depending on the shape of an object and purpose. We propose a fast grasp synthesis ... -
Feature-Preserving Displacement Mapping With Graphics Processing Unit (GPU) Tessellation
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Displacement mapping reconstructs a high‐frequency surface by adding geometric details encoded in the displacement map to the coarse base surface. In the context of hardware tessellation supported by GPUs, this paper aims ... -
Feature-Preserving Reconstruction of Singular Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Reconstructing a surface mesh from a set of discrete point samples is a fundamental problem in geometric modeling. It becomes challenging in presence of 'singularities' such as boundaries, sharp features, and non-manifolds. ... -
Finding Surface Correspondences Using Symmetry Axis Curves
(The Eurographics Association and Blackwell Publishing Ltd., 2012)In this paper, we propose an automatic algorithm for finding a correspondence map between two 3D surfaces. The key insight is that global reflective symmetry axes are stable, recognizable, semantic features of most real-world ... -
Flexible Developable Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We introduce a discrete paradigm for developable surface modeling. Unlike previous attempts at interactive developable surface modeling, our system is able to enforce exact developability at every step, ensuring that users ... -
From A Medial Surface To A Mesh
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Medial surfaces are well-known and interesting surface skeletons. As such, they can describe the topology and the geometry of a 3D closed object. The link between an object and its medial surface is also intuitively ... -
Fur Shading and Modification based on Cone Step Mapping
(The Eurographics Association and Blackwell Publishing Ltd., 2012)This paper presents an algorithm for the real time rendering of fur without adding fur-specific geometry, such as shells, to the object. It is based on Cone Step Mapping and introduces a local distortion of the view vector ... -
Gamut Mapping Spatially Varying Reflectance with an Improved BRDF Similarity Metric
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Recent spatially varying reflectance (svBRDF) printing systems can reproduce an input document as a combination of matte, glossy and metallic inks. Due to the limited number of inks, this reproduction process incurs some ... -
Generalized Model-Based Human Motion Recognition with Body Partition Index Maps
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Content-based human motion analysis has captured extensive concerns of researchers from the domains of computer animation, human-machine interaction, entertainment, etc. However, it is a non-trivial task due to the spatial ... -
Generalized Swept Mid-structure for Polygonal Models
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce a novel mid-structure called the generalized swept mid-structure (GSM) of a closed polygonal shape, and a framework to compute it. The GSM contains both curve and surface elements and has consistent sheet-by-sheet ... -
Geodesic Polar Coordinates on Polygonal Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Geodesic Polar Coordinates (GPCs) on a smooth surface -
Geometry Presorting for Implicit Object Space Partitioning
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a new data structure for object space partitioning that can be represented completely implicitly. The bounds of each node in the tree structure are recreated at run-time from the scene objects contained therein. ... -
A Global Parity Measure for Incomplete Point Cloud Data
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Shapes with complex geometric and topological features such as tunnels, neighboring sheets, and cavities are susceptible to undersampling and continue to challenge existing reconstruction techniques. In this work we introduce ... -
GPU Shape Grammars
(The Eurographics Association and Blackwell Publishing Ltd., 2012)GPU Shape Grammars provide a solution for interactive procedural generation, tuning and visualization of massive environment elements for both video games and production rendering. Our technique generates detailed models ... -
A GPU-based Approach for Massive Model Rendering with Frame-to-Frame Coherence
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Rendering massive 3D models in real-time has long been recognized as a very challenging problem because of the limited computational power and memory space available in a workstation. Most existing rendering techniques, ... -
Graph Bundling by Kernel Density Estimation
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a fast and simple method to compute bundled layouts of general graphs. For this, we first transform a given graph drawing into a density map using kernel density estimation. Next, we apply an image sharpening ... -
Growing Least Squares for the Analysis of Manifolds in Scale-Space
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We present a novel approach to the multi-scale analysis of point-sampled manifolds of co-dimension 1. It is based on a variant of Moving Least Squares, whereby the evolution of a geometric descriptor at increasing scales ...
