Aila (editors) MITSUBISHI ELECTRIC Mitsubishi Electric Research Laboratories ISSN 1017-4656 Impressum c 2006 The Eurographics Association ISSN 1017-4656 Produced by: Institute of Computer Graphics and Algorithms Technical University Vienna, A-1040, Austria Cover Design: Katharina Bruckner Print Preparation: Georg Zotti, TU Vienna September 4–8, 2006 Vienna, Austria Graphics meets Games Preface These proceedings contain abstracts of all the items presented in the “Graphics meets Games” track at Eurographics 2006, the 27th Conference of the European Association for Computer Graphics, held in the buildings of the Austrian Academy of Sciences in Vienna, Austria, between the 4th and the 8th of September 2006. Digital games have paved the way for computer graphics to become a mainstream technology. Con- versely, computer graphics has elevated digital games to a popularity never seen before. Eurographics acknowledges this fact by dedicating a whole new program track to the interface between these two disciplines. Read on to learn more about the very first “Graphics meets Games” program, including special in- dustry talks, a panel, physical games, and an exciting competition! We would like to extend our special gratitude to Markus Giegl, who took care of the Graphics meets Games competition, NVIDIA and the European GameTools project for sponsoring the prizes for the competition, and Georg Zotti for his unrelenting efforts to get the proceedings you hold in your hand into print.

    Proceedings of the 2018 Winter Simulation Conference M. Rabe, A.A. Juan, N. Mustafee, A. Skoogh, S. Jain, and B. Johansson, eds. PHYSX AS A MIDDLEWARE FOR DYNAMIC SIMULATIONS IN THE CONTAINER LOADING PROBLEM Juan C. Martínez-Franco David Álvarez-Martínez Department of Mechanical Engineering Department of Industrial Engineering Universidad de Los Andes Universidad de Los Andes Carrera 1 Este No. 19A – 40 Carrera 1 Este No. 19A – 40 Bogotá, 11711, COLOMBIA Bogotá, 11711, COLOMBIA ABSTRACT The Container Loading Problem (CLP) is an optimization challenge where the constraint of dynamic stability plays a significant role. The evaluation of dynamic stability requires the use of dynamic simulations that are carried out either with dedicated simulation software that produces very small errors at the expense of simulation speed, or real-time physics engines that complete simulations in a very short time at the cost of repeatability. One such engine, PhysX, is evaluated to determine the feasibility of its integration with the open source application PackageCargo. A simulation tool based on PhysX is proposed and compared with the dynamic simulation environment of Autodesk Inventor to verify its reliability. The simulation tool presents a dynamically accurate representation of the physical phenomena experienced by cargo during transportation, making it a viable option for the evaluation of dynamic stability in solutions to the CLP. 1 INTRODUCTION The Container Loading Problem (CLP) consists of the geometric arrangement of small rectangular items (cargo) into a larger rectangular space (container), but it is not a simple geometry problem. The arrangements of cargo must maximize volume utilization while complying with certain constraints such as cargo fragility, delivery order, etc.
