Manipulation of Flexible Objects by Geodesic Control
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We propose an effective and intuitive method for controlling flexible models such as ropes and cloth. Automating manipulation of such flexible objects is not an easy task due to the high dimensionality of the objects and ... -
Manufacturing Layered Attenuators for Multiple Prescribed Shadow Images
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a practical and inexpensive method for creating physical objects that cast different color shadow images when illuminated by prescribed lighting configurations. The input to our system is a number of lighting ... -
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 ... -
Mesh Colorization
(The Eurographics Association and John Wiley and Sons Ltd., 2012)This paper proposes a novel algorithm for colorization of meshes. This is important for applications in which the model needs to be colored by just a handful of colors or when no relevant image exists for texturing the ... -
Metering for Exposure Stacks
(The Eurographics Association and John Wiley and Sons Ltd., 2012)When creating a High-Dynamic-Range (HDR) image from a sequence of differently exposed Low-Dynamic-Range (LDR) images, the set of LDR images is usually generated by sampling the space of exposure times with a geometric ... -
Multitouch Gestures for Constrained Transformation of 3D Objects
(The Eurographics Association and John Wiley and Sons Ltd., 2012)3D transformation widgets allow constrained manipulations of 3D objects and are commonly used in many 3D applications for fine-grained manipulations. Since traditional transformation widgets have been mainly designed for ... -
NoRM: No-Reference Image Quality Metric for Realistic Image Synthesis
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Synthetically generating images and video frames of complex 3D scenes using some photo-realistic rendering software is often prone to artifacts and requires expert knowledge to tune the parameters. The manual work required ... -
Novel-View Synthesis of Outdoor Sport Events Using an Adaptive View-Dependent Geometry
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We propose a novel fully automatic method for novel-viewpoint synthesis. Our method robustly handles multicamera setups featuring wide-baselines in an uncontrolled environment. In a first step, robust and sparse point ... -
Perceptually Linear Parameter Variations
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Most visual analysis tasks require interactive adjustment of parameter values. In general, a linear variation of a parameter, using for instance a GUI slider, changes the visual result in a perceptually non-linear way. ... -
Pixel Art with Refracted Light by Rearrangeable Sticks
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Pixel art is a kind of digital art that through per-pixel manipulation enables production of a diverse array of artistic images. In this paper, we present a new way for people to experience and express pixel art. Our digital ... -
Practical Spectral Photography
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce a low-cost and compact spectral imaging camera design based on unmodified consumer cameras and a custom camera objective. The device can be used in a high-resolution configuration that measures the spectrum ... -

Procedural Generation of Parcels in Urban Modeling
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a method for interactive procedural generation of parcels within the urban modeling pipeline. Our approach performs a partitioning of the interior of city blocks using user-specified subdivision attributes and ... -
Procedural Interpolation of Historical City Maps
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We propose a novel approach for the temporal interpolation of city maps. The input to our algorithm is a sparse set of historical city maps plus optional additional knowledge about construction or destruction events. The ... -
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 ... -
Rasterized Bounding Volume Hierarchies
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present the rasterized bounding volume hierarchy (RBVH), a compact data structure that accelerates approximate ray casting of complex meshes and provides adjustable level of detail. During construction, we identify ... -
Rationalization of Triangle-Based Point-Folding Structures
(The Eurographics Association and John Wiley and Sons Ltd., 2012)In mechanical engineering and architecture, structural elements with low material consumption and high loadbearing capabilities are essential for light-weight and even self-supporting constructions. This paper deals with ... -
Real-Time Disparity Map-Based Pictorial Depth Cue Enhancement
(The Eurographics Association and John Wiley and Sons Ltd., 2012)The availability of stereoscopic image material is increasing rapidly. In contrast to the generation of distance information, displaying it is still a challenging task. To overcome the need for special 3D display hardware, ... -
Real-time Realistic Rendering and Lighting of Forests
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Realistic real-time rendering and lighting of forests is an important aspect for simulators and video games. This is a difficult problem, due to the massive amount of geometry: aerial forest views display millions of trees ... -
Real-time Rendering of Dynamic Scenes under All-frequency Lighting using Integral Spherical Gaussian
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We propose an efficient rendering method for dynamic scenes under all-frequency environmental lighting. To render the surfaces of objects illuminated by distant environmental lighting, the triple product of the lighting, ...
