Data Driven Surface Reflectance from Sparse and Irregular Samples
(The Eurographics Association and John Wiley and Sons Ltd., 2012)In recent years, measuring surface reflectance has become an established method for high quality renderings. In this context, especially non-parametric representations got a lot of attention as they allow for a very accurate ... -
Data-Driven Estimation of Cloth Simulation Models
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Progress in cloth simulation for computer animation and apparel design has led to a multitude of deformation models, each with its own way of relating geometry, deformation, and forces. As simulators improve, differences ... -
Data-Driven Object Manipulation in Images
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a framework for interactively manipulating objects in a photograph using related objects obtained from internet images. Given an image, the user selects an object to modify, and provides keywords to describe it. ... -
Explicit Mesh Surfaces for Particle Based Fluids
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce the idea of using an explicit triangle mesh to track the air/fluid interface in a smoothed particle hydrodynamics (SPH) simulator. Once an initial surface mesh is created, this mesh is carried forward in time ... -
Exploring Shape Variations by 3D-Model Decomposition and Part-based Recombination
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a system that allows new shapes to be created by blending between shapes taken from a database. We treat the shape as a composition of parts; blending is performed by recombining parts from different shapes ... -
Factored Facade Acquisition using Symmetric Line Arrangements
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce a novel framework for image-based 3D reconstruction of urban buildings based on symmetry priors. Starting from image-level edges, we generate a sparse and approximate set of consistent 3D lines. These lines ... -
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 ... -
Generalized Swept Mid-structure for Polygonal Models
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce a novel mid-structure called the generalized swept mid-structure (GSM) of a closed polygonal shape, and a framework to compute it. The GSM contains both curve and surface elements and has consistent sheet-by-sheet ... -
A GPU-based Approach for Massive Model Rendering with Frame-to-Frame Coherence
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Rendering massive 3D models in real-time has long been recognized as a very challenging problem because of the limited computational power and memory space available in a workstation. Most existing rendering techniques, ... -
How Not to Be Seen -- Object Removal from Videos of Crowded Scenes
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Removing dynamic objects from videos is an extremely challenging problem that even visual effects professionals often solve with time-consuming manual frame-by-frame editing. We propose a new approach to video completion ... -
Importance Caching for Complex Illumination
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Realistic rendering requires computing the global illumination in the scene, and Monte Carlo integration is the best-known method for doing that. The key to good performance is to carefully select the costly integration ... -
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 ... -
Interactive Coherence-Based Façade Modeling
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We propose a novel interactive framework for modeling building façades from images. Our method is based on the notion of coherence-based editing which allows exploiting partial symmetries across the façade at any level of ... -
Interactive Editing of GigaSample Terrain Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Previous terrain rendering approaches have addressed the aspect of data compression and fast decoding for rendering, but applications where the terrain is repeatedly modified and needs to be buffered on disk have not been ... -
Interactive Multi-perspective Imagery from Photos and Videos
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Photographs usually show a scene from a single perspective. However, as commonly seen in art, scenes and objects can be visualized from multiple perspectives. Making such images manually is time consuming and tedious. We ... -
Interactive Self-Organizing Windows
(The Eurographics Association and John Wiley and Sons Ltd., 2012)In this paper, we present the design and implementation of a dynamic window management technique that changes the perception of windows as fixed-sized rectangles. The primary goal of self-organizing windows is to automatically ... -
Iterative Image Warping
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Animated image sequences often exhibit a large amount of inter-frame coherence which standard rendering algorithms and pipelines are ill-equipped to exploit, limiting their efficiency. To address this inefficiency we ... -
Light-Field Retargeting
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a first approach to light-field retargeting using z-stack seam carving, which allows light-field compression and extension while retaining angular consistency. Our algorithm first converts an input light field ... -
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 ... -
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 ...
