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

      Dévai, F. (The Eurographics Association, 1987)

    • Object Calibration for Augmented Reality 

      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 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 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 ...
    • Object Snapping Method using Multi-Resolution Fuzzy Grid Snapping Technique 

      Dematapitiya, Sumudu; Kawazoe, Masatoshi; Khand, Qamar Uddin; Saga, Sato (The Eurographics Association, 2005)
      We propose the automatic snapping of objects using the Multi-resolution Fuzzy Grid Snapping (MFGS) for a sketch based CAD system. The sketch based CAD system, which has already been realized, identifies sketch drawings as ...
    • Object Space EWA Surface Splatting: A Hardware Accelerated Approach to High Quality Point Rendering 

      Ren, Liu; Pfister, Hanspeter; Zwicker, Matthias (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      Elliptical weighted average (EWA) surface splatting is a technique for high quality rendering of point-sampled 3D objects. EWA surface splatting renders water-tight surfaces of complex point models with high quality, ...
    • Object-aware Gradient-Domain Image Compositing 

      Eisemann, Martin; Kokemüller, Jan; Magnor, Marcus (The Eurographics Association, 2011)
      We describe an approach to suppress bleeding artifacts without altering the boundary location in gradient-domain compositing, a technique to create seamless composites. While gradient-domain compositing has become a stan- ...
    • An Object-Oriented Approach to Process Monitoring 

      Hütter, Ronald (Eurographics Association, 1988)
