VIRTUAL WORLDS AND CONSERVATIONAL CHANNEL EVOLUTION AND POLLUTANT TRANSPORT SYSTEMS (CONCEPTS) A Dissertation Submitted to the Faculty of the University of Mississippi in partial fulfillment of the requirements for the Degree of Doctor of Philosophy in the School of Engineering The University of Mississippi by CHENCHUTTA DENAYE CROSS JACKSON July 2012 Copyright © 2012 by Chenchutta Cross Jackson All rights reserved ABSTRACT Many models exist that predict channel morphology. Channel morphology is defined as the change in geometric parameters of a river. Channel morphology is affected by many factors. Some of these factors are caused either by man or by nature. To combat the adverse effects that man and nature may cause to a water system, scientists and engineers develop stream rehabilitation plans. Stream rehabilitation as defined by Shields et al., states that “restoration is the return from a degraded ecosystem back to a close approximation of its remaining natural potential” [Shields et al., 2003]. Engineers construct plans that will restore streams back to their natural state by using techniques such as field investigation, analytical models, or numerical models. Each of these techniques is applied to projects based on specified criteria, objectives, and the expertise of the individuals devising the plan. The utilization of analytical and numerical models can be difficult, for many reasons, one of which is the intuitiveness of the modeling process. Many numerical models exist in the field of hydraulic engineering, fluvial geomorphology, landscape architecture, and stream ecology that evaluate and formulate stream rehabilitation plans. This dissertation will explore, in the field of “Hydroscience”, the creation of models that are not only accurate but also span the different disciplines. The goal of this dissertation is to transform a discrete numerical model (CONCEPTS) into a realistic 3D environment using open source game engines, while at the same time, conveying at least the equivalent information that was presented in the 1D numerical model. ii DEDICATION First, I would like to give all honor and glory to my Almighty God. He has made all my impossible possible. I dedicate this paper to my supportive family Marlon, Kentarvis, Christopher, and Aiden. You guys have made this journey worthwhile. Also I dedicate this to my grandmother Rosie Lee Cross. Without your faith and love for me, I would not be who I am today. iii ACKNOWLEDGMENTS I would like to take the time to express my deepest appreciation to my advisor, Dr. Pamela Lawhead and my committee members, Dr. Dawn Wilkins, Dr. Yixin Chen, Dr. Conrad Cunningham, and Dr. Eddy Langendoen. I would like to also express my gratitude to the University of Mississippi Graduate School for patience and funding as well as the United States Department of Agriculture for their commitment and involvement. I would like to thank my friend Doris Turnage for her support and advice throughout this entire process. Lastly, I would not have gotten this far without the support and help of my loving husband Marlon Jackson. You have stood by my side and loved me through it all. iv TABLE OF CONTENTS ABSTRACT ……………………………………………………………………..……….ii DEDICATION ………………………………………………………………..…………iii

Este trabalho enquadra-se numa perspectiva de poder introduzir o desenvolvimento de experiências virtuais com interacção háptica no ensino, estando definido como objectivo a concepção de um conjunto de metodologias que permitam criar este tipo de experiências de forma simples e rápida. Inicia-se assim o trabalho com uma revisão bibliográfica das áreas envolvidas, nomeadamente simulação por computador, computação gráfica, realidade virtual e interacção háptica. Seguidamente são investigadas e analisadas possíveis soluções actualmente existentes e passíveis de serem aplicadas. Dado que não se encontrou uma solução que satisfizesse as necessidades do problema, apresenta-se uma análise das tecnologias necessárias para conceber uma nova solução: motor gráfico, motor físico e dispositivo háptico. As duas primeiras tecnologias referidas são alvo de uma avaliação, que permite escolher, de entre um conjunto de opções, qual o motor gráfico e físico que melhor se adequa às necessidades.

    Estudo Comparativo Entre Engines De Jogos

    FACULDADE DE TECNOLOGIA, CIÊNCIAS E EDUCAÇÃO Graduação GRADUAÇÃO EM CIÊNCIA DA COMPUTAÇÃO Estudo comparativo entre engines de jogos Carlos Gabriel Agostinho Gonçalo Klinke Adinovam Henriques de Macedo Pimenta (Orientador) RESUMO A evolução das engines está agora se movendo para jogos mais realistas e tecnicamente ricos em vários campos, como a física, sons e renderização. Das primeiras engines até as engines mais atuais voltadas para jogos 3D, o objetivo do desenvolvimento permanece o mesmo: fornecer ao desenvolvedor uma plataforma para criar jogos exclusivos de tal maneira que os desenvolvedores não precisem escrever ou desenvolver o jogo a partir do zero, mas apenas implementar a ideia com a ajuda de uma engine. Desta maneira, muitos desenvolvedores (experientes ou iniciantes) têm encontrado nestas ferramentas a maneira mais simples, rápida e profissional de desenvolver novos jogos. Porém, com tantas engines disponíveis, o desenvolvedor precisa fazer uma escolha considerando os dados mais relevantes ao seu projeto. Este trabalho analisou dados de vários atributos relevantes ao processo de escolha considerando as 10 engines mais populares atualmente, servindo de conhecimento e auxílio à este processo decisório. Palavras-chave: Motores de jogos. Desenvolvimento de jogos. Jogos digitais.

  • Introduction to Opengl

    Introduction to Opengl

    INTRODUCTION TO OPENGL Pramook Khungurn CS4620, Fall 2012 What is OpenGL? • Open Graphics Library • Low level API for 2D/3D rendering with GPU • For interactive applications • Developed by SGI in 1992 • 2009: OpenGL 3.2 • 2010: OpenGL 4.0 • 2011: OpenGL 4.2 • Competitor: Direct3D OpenGL 2.x vs OpenGL 3.x • We’ll teach you 2.x. • Since 3.x, a lot of features of 2.x have been deprecated. • Becoming more similar to DirectX • Deprecated features are not removed. • You can still use them! • Why? • Backward compatibility: Mac cannot fully use 3.x yet. • Pedagogy. Where does it work? What OpenGL Does • Control GPU to draw simple polygons. • Utilize graphics pipeline. • Algorithm GPU uses to create 3D images • Input: Polygons & other information • Output: Image on framebuffer • How: Rasterization • More details in class next week. What OpenGL Doesn’t Do • Manage UI • Manage windows • Decide where on screen to draw. • It’s your job to tell OpenGL that. • Draw curves or curved surfaces • Although can approximate them by fine polygons Jargon • Bitplane • Memory that holds 1 bit of info for each pixel • Buffer • Group of bitplanes holding some info for each pixel • Framebuffer • A buffer that hold the image that is displayed on the monitor. JOGL Java OpenGL (JOGL) • OpenGL originally written for C. • JOGL = OpenGL binding for Java • http://jogamp.org/jogl/www/ • Gives Java interface to C OpenGL commands. • Manages framebuffer. Demo 1 GLCanvas • UI component • Can display images created by OpenGL. • OpenGL “context” • Stores OpenGL states. • Provides a default framebuffer to draw. • Todo: • Create and stick it to a window.
