Constructing Isosurfaces with Sharp Edges and Corners using Cube Merging
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
A number of papers present algorithms to construct isosurfaces with sharp edges and corners from hermite data, i.e. the exact surface normals at the exact intersection of the surface and grid edges. We discuss some fundamental ...
Indoor Scene Reconstruction using Primitive-driven Space Partitioning and Graph-cut
(The Eurographics Association, 2013)
We present a method for automatic reconstruction of permanent structures of indoor scenes, such as walls, floors and ceilings, from raw point clouds acquired by laser scanners. Our approach employs graph-cut to solve an ...
Geometric Histograms of 3D Keypoints for Face Identification with Missing Parts
(The Eurographics Association, 2013)
In this work, an original solution to 3D face identification is proposed, which supports recognition also in the case of probes with missing parts. Distinguishing traits of the face are captured by first extracting 3D ...
Creating Contour Gradients using 3D Bevels
(ACM, 2013)
Contour gradients have color contours that follow the shape of the path being filled. Existing algorithms cannot create them in a resolution- and scale-independent way, causing visible rendering artifacts if enlarged. We ...
Animation-Aware Quadrangulation
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Geometric meshes that model animated characters must be designed while taking into account the deformations that the shape will undergo during animation. We analyze an input sequence of meshes with point-to-point correspondence, ...
Surface Patches for 3D Sketching
(ACM, 2013)
3D sketching is an appealing approach for creating concept shapes in the early stages of design. While curve networks alone can convey shape, surfacing the network can dramatically help with visualization and interaction. ...
A Level Set Method for Ductile Fracture
(ACM SIGGRAPH / Eurographics Association, 2013)
We utilize the shape derivative of the classical Griffith's energy in a level set method for the simulation of dynamic ductile fracture. The level set is defined in the undeformed configuration of the object, and its ...
