Approximating the Generalized Voronoi Diagram of Closely Spaced Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present an algorithm to compute an approximation of the generalized Voronoi diagram (GVD) on arbitrary collections of 2D or 3D geometric objects. In particular, we focus on datasets with closely spaced objects; GVD ... -
Composition-Aware Scene Optimization for Product Images
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Increasingly, companies are creating product advertisements and catalog images using computer renderings of 3D scenes. A common goal for these companies is to create aesthetically appealing compositions that highlight ... -
Designing Camera Networks by Convex Quadratic Programming
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In this paper, we study the problem of automatic camera placement for computer graphics and computer vision applications. We extend the problem formulations of previous work by proposing a novel way to incorporate visibility ... -
Layer-Based Procedural Design of Façades
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a novel procedural framework for interactively modeling building façades. Common procedural approaches, such as shape grammars, assume that building façades are organized in a tree structure, while in practice ... -
Optimal Spline Approximation via l0-Minimization
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Splines are part of the standard toolbox for the approximation of functions and curves in Rd. Still, the problem of finding the spline that best approximates an input function or curve is ill-posed, since in general this ... -
Template Assembly for Detailed Urban Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We propose a new framework to reconstruct building details by automatically assembling 3D templates on coarse textured building models. In a preprocessing step, we generate an initial coarse model to approximate a point ... -
Woodification: User-Controlled Cambial Growth Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a botanical simulation of secondary (cambial) tree growth coupled to a physical cracking simulation of its bark. Whereas level set growth would use a fixed resolution voxel grid, our system extends the deformable ...
