      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 ...
    • LeoMCAD: A Lego-based Mechanical CAD system 

      García, Francisco González; Martín, Jesús Amador Pérez; Patow, Gustavo A. (The Eurographics Association, 2018)
      Mechanical Design (MCAD) tools are used for creating 3D digital prototypes used in the design, visualization, and simulation of products. In this paper we present LeoMCAD, a Lego-based mechanical system designed to be used ...
    • Level of Detail for Physically Based Fire 

      Gundersen, Odd Erik; Tangvald, Lars (The Eurographics Association, 2007)
      In this paper, we propose a framework for implementing level of detail for a physically based fire rendering running on the GPU. The physics of the fire is simulated using a fluid solver and combustion modelling, and the ...
