    • An O(log N) Parallel Time Exact Hidden-LineAlgorithm 

      Dévai, F. (The Eurographics Association, 1987)
      "Parallel algorithms are given for the exact solution of the hidden-line problem. Most of the parallel algorithms proposed for visibility problems in the literature give approximate solutions. and thus cannot yield an upper ...

      Whitaker, Ross T.; Crampton, Chris; Breen, David E.; Tuceryan, Mihran; Rose, Eric (Blackwell Science Ltd and the Eurographics Association, 1995)
      Augmented reality involves the use of models and their associated renderings to supplement information in a real scene. In order for this information to be relevant or meaningful, the models must be positioned and displayed ...
    • Object Completion using k-Sparse Optimization 

      Mavridis, Pavlos; Sipiran, Ivan; Andreadis, Anthousis; Papaioannou, Georgios (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present a new method for the completion of partial globally-symmetric 3D objects, based on the detection of partial and approximate symmetries in the incomplete input dataset. In our approach, symmetry detection is ...
    • Object Detection and Classification from Large-Scale Cluttered Indoor Scans

      We present a method to automatically segment indoor scenes by detecting repeated objects. Our algorithm scales to datasets with 198 million points and does not require any training data. We propose a trivially parallelizable ...
    • Object Hierarchies for Efficient Rendering 

      Mueller, Gordon (Mueller, 2004)
      The efficient synthesis of computer generated images for large three-dimensional modelsis one of the major challenges of computer graphics research. Despite the rapid growth ofavailable computational power of todays ...
    • Object Interaction Using Tabulated Spheres Subsets 

      Newball, Andres A. Navarro; Wyvill, Geoff; McCane, Brendan (The Eurographics Association, 2009)
      Tabulated Sphere Subsets (TSSs) provide a fast way to approximate collision tests between objects whose motion is constrained. A TSS is a subset of a set of spheres that approximate the shape of two objects that might ...
    • An Object Model for Multimedia Programming 

      Arbab, F.; Herman, I.; Reynolds, G.J. (Blackwell Science Ltd and the Eurographics Association, 1993)
      The development of multimedia applications is a complex task. Much of this complexity stems from requirements associated with programming multiple media objects and the control of dependences and inter-relationships between ...
    • AN OBJECT ORIENTED APPROACH TO ENSURE PORTABILITY OF CAD STANDARD PARTS LIBRARIES 

      Pierra, Guy (Eurographics Association, 1990)
      The integration, in CAD systems, of libraries of standard parts is often considered to be one of the key factors for increasing productivity of Computer Aided Design [1] [2] [3]. These libraries must be able to integrate ...
    • Object Partitioning Considered Harmful: Space Subdivision for BVHs 

      Popov, Stefan; Georgiev, Iliyan; Dimov, Rossen; Slusallek, Philipp (The Eurographics Association, 2009)
      A major factor for the efficiency of ray tracing is the use of good acceleration structures. Recently, bounding volume hierarchies (BVHs) have become the preferred acceleration structures, due to their competitive performance ...
    • Object Partitioning for Support-Free 3D-Printing 

      Karasik, Eli; Fattal, Raanan; Werman, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Fused deposition modeling based 3D-printing is becoming increasingly popular due to it's low-cost and simple operation and maintenance. While it produces rugged prints made from a wide range of materials, it suffers from ...
    • Object Repositioning Based on the Perspective in a Single Image 

      Iizuka, S.; Endo, Y.; Hirose, M.; Kanamori, Y.; Mitani, J.; Fukui, Y. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We propose an image editing system for repositioning objects in a single image based on the perspective of the scene. In our system, an input image is transformed into a layer structure that is composed of object layers ...
