      This paper describes an augmented reality application that aids users in assembling an object originally in a kit format, i.e. the object is received unassembled, with ordered instructions steps on how to connect each ...
    • Knee Up: an Exercise Game for Standing Knee Raises by Motion Capture with RGB-D Sensor 

      Kiziltas, D.; Celikcan, U. (The Eurographics Association, 2018)
      In this work, we present the design and the implementation of Knee Up, an exergame that promotes knee health via standing knee raises exercises. It allows users to exercise at home and perform the exercise in a gaming ...
    • Knight Lore 20xx: Bringing a Classic Game to Modern Technology 

      Galvany, Ricard; Patow, Gustavo (The Eurographics Association, 2016)
      This paper reports about the experience, problems encountered, and the solutions found to develop Knight Lore 20XX, an experiment of using Computer Graphics techniques to bring a classic game from the 80's to modern technology.
    • Knowledge-based Discovery of Transportation Object Properties by Fusing Multi-modal GIS Data 

      Maroun, Pedro Eid; Mudur, Sudhir; Popa, Tiberiu (The Eurographics Association, 2018)
      3D models of transportation objects like a road, bridge, underpass, etc. are required in many domains including military training, land development, etc. While remote sensed images and LiDaR data can be used to create ...
    • Large Scale Pedestrian Multi-Simulation for a Decision Support Tool 

      Karmakharm, Twin; Richmond, Paul (The Eurographics Association, 2012)
      Ability to simulate pedestrian behaviour on a large scale is essential in identifying potential dangers in public spaces during an evacuation. Multiple designs must be tested with varying parameters and run multiple times ...
    • A Lemon is not a Monstar: Visualization of Singularities of Symmetric Second Rank Tensor Fields in the Plane 

      Liu, J.; Hewitt, W. T.; Lionheart, W. R. B.; Montaldi, J.; Turner, M. (The Eurographics Association, 2008)
      In the visualization of the topology of second rank symmetric tensor fields in the plane one can extract some key points (degenerate points), and curves (separatrices) that characterize the qualitative behaviour of the ...
