Download Simulation Software for Free to Help Them to Learn How to Create Electrical Power Networks Project Number: DC MQP 1102 Empowerment Simulation System April 23, 2012 A Major Qualifying Project Report: Submitted to the Faculty of WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Bachelor of Science in Interactive Media and Game Development By: Timothy Kolek Advised by: Professor David Cyganski Abstract Empowerment is a new game being developed by WPI and FIRST, inspired by the FIRST Robotics Competition, aimed at educating high school students about Energy. The project goal was creation of a sandbox for game physics and GUI exploration. It allows a player to configure electrical power networks using 3D models of various (and adjustable) types of generators, consumers, transmission towers and interconnecting power lines. The simulator demonstrates the automatic solution for power distribution, a core component of game state, based upon system parameters and player choices. The simulator was built upon the JMonkey 3 game engine in Java, yielding an operating system agnostic, open source implementation as a basis for the future game system implementation. 2 Table of

  • Nethomura Deployment Platform and Networking Middleware Is Still Evolving
    Networking Middleware and Online-Deployment Mechanisms for Java-based Games Chris Carter1, Dr Abdennour El Rhalibi1, Prof. Madjid Merabti1, Dr Marc Price2 (1) School of Computing & Mathematical Sciences, Liverpool John Moores University, Byrom Street, Liverpool, L3 3AF, UK [email protected]; [email protected]; [email protected] (2) BBC Research and Development. Kingswood Warren, Tadworth, Surrey, KT20 6NP, UK [email protected] Abstract. Currently, web-based online gaming applications are predominately utilising Adobe Flash or Java Applets as their core technologies. These games are often casual, two- dimensional games and do not utilise the specialist graphics hardware which has proliferated across modern PCs and Consoles. Multi-user online game play in these titles is often either non-existent or extremely limited. Computer games applications which grace the current generation of consoles and personal computers are designed to utilise the increasingly impressive hardware power at their disposal. However, these are commonly distributed using a physical medium or deployed through custom, proprietary networking mechanisms and rely upon platform-specific networking APIs to facilitate multi-user online game play. In order to unify the concepts of these disparate styles of gaming, this paper presents two interconnected systems which are implemented using Java Web Start and JXTA P2P technologies, providing a platform-independent framework capable of deploying hardware accelerated cross-platform, cross-browser online-enabled Java games, as part of the Homura Project. Keywords: Web Technologies, Distributed Systems, Java, Homura, NetHomura, Java Monkey Engine, jME, Java Web Start, Deployment, JXTA, Peer to Peer Networking, P2P Games.

  • Advanced 3D Visualization for Simulation Using Game Technology
    Proceedings of the 2011 Winter Simulation Conference S. Jain, R. R. Creasey, J. Himmelspach, K. P. White, and M. Fu, eds. ADVANCED 3D VISUALIZATION FOR SIMULATION USING GAME TECHNOLOGY Jonatan L. Bijl Csaba A. Boer TBA B.V. Karrepad 2a 2623 AP Delft, Netherlands ABSTRACT 3D visualization is becoming increasingly popular for discrete event simulation. However, the 3D visu- alization of many of the commercial off the shelf simulation packages is not up to date with the quickly developing area of computer graphics. In this paper we present an advanced 3D visualization tool, which uses game technology. The tool is especially fit for discrete event simulation, it is easily configurable, and it can be kept up to date with modern computer graphics techniques. The tool has been used in several container terminal simulation projects. From a survey under simulation experts and our experience with the visualization tool, we concluded that realism is important for some of the purposes of visualization, and the use of game technology can help to achieve this goal. 1 INTRODUCTION Simulation is the process of designing a model of a concrete system and conducting experiments with this model in order to understand the behavior of the concrete system and/or evaluate various strategies for the operation of the system (Shannon 1975). Although the simulation experiment can produce a large amount of data, the visualization of a simulated system provides a more complete understanding of its behavior. In the visualization, key elements of the system are represented on the screen by icons that dynamically change position, color and shape as the simulation evolves through time (Law and Kelton 2000).

  • Visual Representation of 3D Language Constructs Specified By
    Visual Representation of 3D Language Constructs Specified by Generic Depictions Jan Wolter University of Paderborn Department of Computer Science F¨urstenallee11, 33102 Paderborn, Germany [email protected] Abstract Several modeling domains make use of three-dimensional representations, e.g., the \ball-and-stick" models of molecules. Our generator framework DEViL3D supports the design and implementation of visual 3D languages for such modeling purposes. The front-end of a language implementation generated by DEViL3D is a dedicated 3D graphical structure editor, which is used to con- struct programs in that domain. DEViL3D supports the language designer to describe the visual appearance of the constructs of the particular language in terms of generic 3D depictions. Their parameters specify where substructures are embedded, and how the graphic adapts to space requirements of nested con- structs. The 3D editor used for such specifications is generated by DEViL3D, too. In this paper, we briefly introduce the research field of 3D visual lan- guages and report about our generator framework and the role that generic depictions play in the specification process for 3D languages. Our results show that our approach is suitable for a wide range of 3D languages. We emphasize this suitability by presenting requirements on the visual appearance for different languages. Key words. three-dimensional depictions, visual languages, visual program- ming, automated generation, 3D interaction techniques.

  • Game Design and Development Course Taught with Alice
    GAME DESIGN AND DEVELOPMENT COURSE TAUGHT WITH ALICE Karen Villaverde, Daniel Jaramillo New Mexico State University 1290 Frenger Mall SH 123, Las Cruces, NM 88003 575-646-3723 [email protected] , [email protected] ABSTRACT In this paper we describe our very positive experience in teaching a game design and development course with Alice as a 3D game development platform. We describe why Alice was chosen as our 3D game development platform, what material was covered, how the course was conducted, the quality of the students’ game projects, features of Alice that students liked for game development, problems that students had when using Alice, and the evaluation of the course. 1. INTRODUCTION We always wanted to teach a game design and development course that would cover the theory behind game design, the use of a 3D game development platform, and also give students enough time to develop two complete games. However, the very steep learning curve of most 3D game development platforms prevented us from doing everything we wanted to do in one semester. Then we decided to give Alice [5] an opportunity. In the spring of 2009, we taught a game design and development course using Alice as our 3D game development platform. The course was fourteen weeks long and was taught in the Computer Science department of New Mexico State University. This was the first time that a game design and development course was taught in our department. The course prerequisite was a data structures and algorithms course. The course was extremely popular and filled up completely on the first day of registration.

KG | 9781430239871 | English | Berlin, Germany Beginning Android 4 Games Development PDF Book Sorry to hear this. Taking a look at how to debug your UE4 project using Android Studio. This post is your one-stop shop to learning Android game development. All of these are really good answer. I know this is easier said than done but it would be nice since libgdx is like the one presented in the original book but on steroids. As you can see then, Android game development can mean many different things depending on your preferred flavour. Difference between RestController and Controller While developing games I learned how to use Physics and Maths in Programming. I already have programming experience in Java but don't have any experience with graphics or animation. Coding in C is necessary for practically any application, and the tool is used by the vast majority of professional game development teams targeting Android. The potential user base and the wide array of available high-performance devices makes Android an attractive target for aspiring game developers. Markus Montola. Android game development tools and options The first thing to decide when starting out with Android game development is what type of game you want to build and what tools you are going to use to do that. When will my order be ready to collect? If I was forced to choose, I would also recommend choosing Unity as the best tool for most developers.
