Multi-scale Feature Extraction on Point-Sampled Surfaces
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We present a new technique for extracting line-type features on point-sampled geometry. Given an unstructuredpoint cloud as input, our method first applies principal component analysis on local neighborhoods toclassify ...
Efficient Raytracing of Deforming Point-Sampled Surfaces
(The Eurographics Association and Blackwell Publishing, Inc, 2005)
Design Transformations for Rule-based Procedural Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We introduce design transformations for rule-based procedural models, e.g., for buildings and plants. Given two or more procedural designs, each specified by a grammar, a design transformation combines elements of the ...
Discovering Structured Variations Via Template Matching
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
Understanding patterns of variation from raw measurement data remains a central goal of shape analysis. Such an understanding reveals which elements are repeated, or how elements can be derived as structured variations ...
Symmetry in 3D Geometry: Extraction and Applications
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
The concept of symmetry has received significant attention in computer graphics and computer vision research in recent years. Numerous methods have been proposed to find, extract, encode and exploit geometric symmetries ...
Adaptive Space Deformations Based on Rigid Cells
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We propose a new adaptive space deformation method for interactive shape modeling. A novel energy formulation based on elastically coupled volumetric cells yields intuitive detail preservation even under large deformations. ...
Conformal Alpha Shapes
(The Eurographics Association, 2005)
We define a new filtration of the Delaunay triangulation of a finite set of points in Rd, similar to the alpha shape filtration. The new filtration is parameterized by a local scale parameter instead of the global scale ...
Robust Articulated-ICP for Real-Time Hand Tracking
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present a robust method for capturing articulated hand motions in realtime using a single depth camera. Our system is based on a realtime registration process that accurately reconstructs hand poses by fitting a 3D ...
Building and Animating User-Specific Volumetric Face Rigs
(The Eurographics Association, 2016)
Currently, the two main approaches to realistic facial animation are 1) blendshape models and 2) physics-based simulation. Blendshapes are fast and directly controllable, but it is not easy to incorporate features such as ...
Surface Reconstruction using Local Shape Priors
(The Eurographics Association, 2007)
We present an example-based surface reconstruction method for scanned point sets. Our approach uses a database of local shape priors built from a set of given context models that are chosen specifically to match a specific ...
