Medial Kernels
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
We introduce the medial kernel, an association measure which provides for a robust construction of volume-aware distances defined directly on point clouds. The medial kernel is a similarity measure defined as the likelihood ...
Soft Stacking
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
In this paper, we present a continuous approach to ordering 2D images when compositing. Previous methods for stacking image layers require them to appear in a single (though possibly different) order at every point in the ...
Crowd Light: Evaluating the Perceived Fidelity of Illuminated Dynamic Scenes
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
Rendering realistic illumination effects for complex animated scenes with many dynamic objects or characters is computationally expensive. Yet, it is not obvious how important such accurate lighting is for the overall ...
Procedural Texture Preview
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
Procedural textures usually require spending time testing parameters to realize the diversity of appearances. This paper introduces the idea of a procedural texture preview: A single static image summarizing in a limited ...
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 ...
Linear Analysis of Nonlinear Constraints for Interactive Geometric Modeling
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
Thanks to its flexibility and power to handle even complex geometric relations, 3D geometric modeling with nonlinear constraints is an attractive extension of traditional shape editing approaches. However, existing approaches ...
crdbrd: Shape Fabrication by Sliding Planar Slices
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
We introduce an algorithm and representation for fabricating 3D shape abstractions using mutually intersecting planar cut-outs. The planes have prefabricated slits at their intersections and are assembled by sliding them ...
Interaction Retrieval by Spacetime Proximity Graphs
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
In this paper, we propose a new method to index and retrieve animation scenes in which multiple characters closely interact with one another. Such a technique can be an important tool for animators when they want to ...
Analytic Anti-Aliasing of Linear Functions on Polytopes
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
This paper presents an analytic formulation for anti-aliased sampling of 2D polygons and 3D polyhedra. Our framework allows the exact evaluation of the convolution integral with a linear function defined on the polytopes. ...
Unstructured Light Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
We present a system for interactively acquiring and rendering light fields using a hand-held commodity camera. The main challenge we address is assisting a user in achieving good coverage of the 4D domain despite the ...
