3D Timeline: Reverse Engineering of a Part-based Provenance from Consecutive 3D Models
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel tool for reverse engineering of modeling histories from consecutive 3D files based on a timeline abstraction. Although a timeline interface is commonly used in 3D modeling packages for animations, it has ... -
4D Video Textures for Interactive Character Appearance
(The Eurographics Association and John Wiley and Sons Ltd., 2014)animation from a database of 4D actor performance captured in a multiple camera studio. 4D performance capture reconstructs dynamic shape and appearance over time but is limited to free-viewpoint video replay of the same ... -
Accurate and Efficient Lighting for Skinned Models
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In the context of real-time, GPU-based rendering of animated skinned meshes, we propose a new algorithm to compute surface normals with minimal overhead both in terms of the memory footprint and the required per-vertex ... -
Adaptive Texture Space Shading for Stochastic Rendering
(The Eurographics Association and John Wiley and Sons Ltd., 2014)When rendering effects such as motion blur and defocus blur, shading can become very expensive if done in a naïve way, i.e. shading each visibility sample. To improve performance, previous work often decouple shading from ... -
Analogy-Driven 3D Style Transfer
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Style transfer aims to apply the style of an exemplar model to a target one, while retaining the target s structure. The main challenge in this process is to algorithmically distinguish style from structure, a high-level, ... -
Art-Photographic Detail Enhancement
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel method for enhancing details in a digital photograph, inspired by the principle of art photography. In contrast to the previous methods that primarily rely on tone scaling, our technique provides a ... -
Automatic Generation of Tourist Brochures
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a novel framework for the automatic generation of tourist brochures that include routing instructions and additional information presented in the form of so-called detail lenses. The first contribution of this ... -
Clean Color: Improving Multi-filament 3D Prints
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Fused Filament Fabrication is an additive manufacturing process by which a 3D object is created from plastic filament. The filament is pushed through a hot nozzle where it melts. The nozzle deposits plastic layer after ... -
Coded Exposure HDR Light-Field Video Recording
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Capturing exposure sequences to compute high dynamic range (HDR) images causes motion blur in cases of camera movement. This also applies to light-field cameras: frames rendered from multiple blurred HDR lightfield ... -
Compressing Dynamic Meshes with Geometric Laplacians
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper addresses the problem of representing dynamic 3D meshes in a compact way, so that they can be stored and transmitted efficiently. We focus on sequences of triangle meshes with shared connectivity, avoiding the ... -
Content-Aware Surface Parameterization for Interactive Restoration of Historical Documents
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present an interactive method to restore severely damaged historical parchments. When damaged by heat in a fire, such manuscripts undergo a complex deformation and contain various geometric distortions such as wrinkling, ... -
Crack-free Rendering of Dynamically Tesselated B-Rep Models
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We propose a versatile pipeline to render B-Rep models interactively, precisely and without rendering-related artifacts such as cracks. Our rendering method is based on dynamic surface evaluation using both tesselation and ... -
Crowd Sculpting: A Space-time Sculpting Method for Populating Virtual Environments
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We introduce "Crowd Sculpting": a method to interactively design populated environments by using intuitive deformation gestures to drive both the spatial coverage and the temporal sequencing of a crowd motion. Our approach ... -
Deformation with Enforced Metrics on Length, Area and Volume
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Techniques have been developed to deform a mesh with multiple types of constraints. One limitation of prior methods is that the accuracy of demanded metrics on the resultant model cannot be guaranteed. Adding metrics ... -
Designing Large-Scale Interactive Traffic Animations for Urban Modeling
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Designing and optimizing traffic behavior and animation is a challenging problem of interest to virtual environment content generation and to urban planning and design. While some traffic simulation methods have appeared ... -
Detection and Reconstruction of Freeform Sweeps
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We study the difficult problem of deciding if parts of a freeform surface can be generated, or approximately generated, by the motion of a planar profile through space. While this task is basic for understanding the geometry ... -
Dual-Color Mixing for Fused Deposition Modeling Printers
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this work we detail a method that leverages the two color heads of recent low-end fused deposition modeling (FDM) 3D printers to produce continuous tone imagery. The challenge behind producing such two-tone imagery is ... -
Efficient Enforcement of Hard Articulation Constraints in the Presence of Closed Loops and Contacts
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In rigid body simulation, one must distinguish between contacts (so-called unilateral constraints) and articulations (bilateral constraints). For contacts and friction, iterative solution methods have proven most useful ... -
Efficient Monte Carlo Rendering with Realistic Lenses
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In this paper we present a novel approach to simulate image formation for a wide range of real world lenses in the Monte Carlo ray tracing framework. Our approach sidesteps the overhead of tracing rays through a system of ... -
ExploreMaps: Efficient Construction and Ubiquitous Exploration of Panoramic View Graphs of Complex 3D Environments
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We introduce a novel efficient technique for automatically transforming a generic renderable 3D scene into a simple graph representation named ExploreMaps, where nodes are nicely placed point of views, called probes, and ...
