    • Accelerating kd-tree Searches for all k-nearest Neighbours 

      Merry, Bruce; Gain, James; Marais, Patrick (The Eurographics Association, 2013)
      Finding the k nearest neighbours of each point in a point cloud forms an integral part of many point-cloud processing tasks. One common approach is to build a kd-tree over the points and then iteratively query the k nearest ...
    • A Correlated Parts Model for Object Detection in Large 3D Scans 

      Sunkel, Martin; Jansen, Silke; Wand, Michael; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      This paper addresses the problem of detecting objects in 3D scans according to object classes learned from sparse user annotation. We model objects belonging to a class by a set of fully correlated parts, encoding dependencies ...
    • Hierarchical Quad Meshing of 3D Scanned Surfaces 

      Bukenberger, Dennis R.; Lensch, Hendrik P. A. (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      In this paper we present a novel method to reconstruct watertight quad meshes on scanned 3D geometry. There exist many different approaches to acquire 3D information from real world objects and sceneries. Resulting point ...
    • Intelligent Interactive Volume Classification 

      Grau, Sergi; Puig, Anna; Escalera, Sergio; Salamó, Maria (The Eurographics Association, 2013)
      This paper defines an intelligent and interactive framework to classify multiple regions of interest from the original data on demand, without requiring any preprocessing or previous segmentation. The proposed intelligent ...
    • Layer-Based Procedural Design of Façades 

      Ilcík, Martin; Musialski, Przemyslaw; Auzinger, Thomas; Wimmer, Michael (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 ...
    • Massively Parallel Batch Neural Gas for Bounding Volume Hierarchy Construction 

      Weller, René; Mainzer, David; Srinivas, Abhishek; Teschner, Matthias; Zachmann, Gabriel (The Eurographics Association, 2014)
      Ordinary bounding volume hierarchy (BVH) construction algorithms create BVHs that approximate the boundary of the objects. In this paper, we present a BVH construction that instead approximates the volume of the objects ...
    • A New Fast and Robust Collision Detection and Force Computation Algorithm Applied to the Physics Engine Bullet: Method, Integration, and Evaluation 

      Sagardia, Mikel; Stouraitis, Theodoros; Silva, Joao Lopes e (The Eurographics Association, 2014)
      We present a collision detection and force computation algorithm based on the Voxelmap-Pointshell Algorithm which was integrated and evaluated in the physics engine Bullet. Our algorithm uses signed distance fields and ...
    • Semantizing Complex 3D Scenes using Constrained Attribute Grammars 

      Boulch, Alexandre; Houllier, Simon; Marlet, Renaud; Tournaire, Olivier (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We propose a new approach to automatically semantize complex objects in a 3D scene. For this, we define an expressive formalism combining the power of both attribute grammars and constraint. It offers a practical conceptual ...
