Cross-Collection Map Inference by Intrinsic Alignment of Shape Spaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Inferring maps between shapes is a long standing problem in geometry processing. The less similar the shapes are, the harder it is to compute a map, or even define criteria to evaluate it. In many cases, shapes appear as ...
Pseudo-Spline Subdivision Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Pseudo-splines provide a rich family of subdivision schemes with a wide range of choices that meet various demands for balancing the approximation power, the length of the support, and the regularity of the limit functions. ...
As-Conformal-As-Possible Surface Registration
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We present a non-rigid surface registration technique that can align surfaces with sizes and shapes that are different from each other, while avoiding mesh distortions during deformation. The registration is constrained ...
Exploring the Geometry of the Space of Shells
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We prove both in the smooth and discrete setting that the Hessian of an elastic deformation energy results in a proper Riemannian metric on the space of shells (modulo rigid body motions). Based on this foundation we develop ...
Functional Fluids on Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Fluid simulation plays a key role in various domains of science including computer graphics. While most existing work addresses fluids on bounded Euclidean domains, we consider the problem of simulating the behavior of an ...
SUPER 4PCS: Fast Global Pointcloud Registration via Smart Indexing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Data acquisition in large-scale scenes regularly involves accumulating information across multiple scans. A common approach is to locally align scan pairs using Iterative Closest Point (ICP) algorithm (or its variants), ...
Remeshing-assisted Optimization for Locally Injective Mappings
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Constructing locally injective mappings for 2D triangular meshes is vital in applications such as deformations. In such a highly constrained optimization, the prescribed tessellation may impose strong restriction on the ...
Semi-sharp Creases on Subdivision Curves and Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We explore a method for generalising Pixar semi-sharp creases from the univariate cubic case to arbitrary degree subdivision curves. Our approach is based on solving simple matrix equations. The resulting schemes allow for ...
A Variational Taxonomy for Surface Reconstruction from Oriented Points
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
The problem of reconstructing a watertight surface from a finite set of oriented points has received much attention over the last decades. In this paper, we propose a general higher order framework for surface reconstruction. ...
