Primitive Trees for Precomputed Distance Queries
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We propose the primitive tree, a novel and compact space-partition method that samples and reconstructs a distance field with high accuracy, even for regions far from the surfaces. The primitive tree is based on the octree ...
Global Selection of Stream Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Stream surfaces are well-known and widely-used structures for 3D flow visualization. A single surface can be sufficient to represent important global flow characteristics. Unfortunately, due to the huge space of possible ...
Geometry-Aware Volume-of-Fluid Method
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present a new framework to simulate moving interfaces in viscous incompressible two phase flows. The goal is to achieve both conservation of the fluid volume and a detailed reconstruction of the fluid surface. To these ...
A Correlated Parts Model for Object Detection in Large 3D Scans
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
This paper addresses the problem of detecting objects in 3D scans according to object classes learned from sparse user annotation. We model objects belonging to a class by a set of fully correlated parts, encoding dependencies ...
Fleshing: Spine-driven Bending with Local Volume Preservation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Several design and animation techniques use a one-dimensional proxyC (a spine curve in 3D) to control the deformation or behavior of a digital model of a 3D shape S. We propose a modification of these ''skinning'' techniques ...
Sifted Disks
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We introduce the Sifted Disk technique for locally resampling a point cloud in order to reduce the number of points. Two neighboring points are removed and we attempt to find a single random point that is sufficient to ...
Exploring Local Modifications for Constrained Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Mesh editing under constraints is a challenging task with numerous applications in geometric modeling, industrial design, and architectural form finding. Recent methods support constraint-based exploration of meshes with ...
Circular Arc Snakes and Kinematic Surface Generation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We discuss the theory, discretization, and numerics of curves which are evolving such that part of their shape, or at least their curvature as a function of arc length, remains unchanged. The discretization of a curve as ...
Landmark-Guided Elastic Shape Analysis of Spherically-Parameterized Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We argue that full surface correspondence (registration) and optimal deformations (geodesics) are two related problems and propose a framework that solves them simultaneously. We build on the Riemannian shape analysis of ...
Mutable Elastic Models for Sculpting Structured Shapes
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
In this paper, we propose a new paradigm for free-form shape deformation. Standard deformable models minimize an energy measuring the distance to a single target shape. We propose a new, ''mutable'' elastic model. It ...
