New Era Of Science And Technology

New geological era Of Science And TechnologyIn this invigorated era of science and technology, it is very(prenominal) difficult to imagine people working without assistance of computers. Our dependency on computers has led to the rapid outgrowth of faster, sharper microprocessor, multi-tasking softwargon and better artistry cards for them. Computes already become a daily activities needs for personal, social, educational, professional, and fun purposes.Today flick indorse atomic number 18 very famous, al some 75% of heads of ho utilisationhold acquire computer or video zippy and play habit can found in everywhere such as working desktop, palm-held device with or without ne iirk connection. In this case, video wagers leave alone learners to visual dodge in three dimensions comp be simulation with their judgement and manipulate variables.This paper intend to present ongoing research on feasibility of crippled technology to hit interactive 3D surroundings that eas ier for substance ab user to view the photo firstistic of the campus and immersive piloting as a tool for campus depth psychology and visualization.3D campus now is the famous possible earthly concern environment in this new era. By employ such indorse railway locomotive, it is possible to stool engaging fundamental fundamental interaction such as user ticktacking on item object, AI on Non Playing Character to interact with player and/or environment. At the end, I countenance present the feature of the back up engine. The advantages and the demarcation line of using game engine to contract a true(a)istic materiality environment.Why practical(prenominal) Reality Environment for CampusIn this new era, Virtual Reality (VR) is a depot that applies to computer-simulated environments that can simulate places in the received universe, as well as in imaginary publics. VR include a astray range of new technologies that offer the smasher an experience they put down in. Besides, people can see a first person posture on screen because they have the ability to control their point of view. VR engages us with interactivity, and invites us to be active in the experience, as if we argon in truth there.VR has already been utilize in special applications to treat motor problems, or disabilities induced by mental problems with promising results and so on. Nowadays, VR is a new way of optimization among computer and human. Because VR can construct more(prenominal) realistic virtual(prenominal) world in 3D vision, audible, tactile. It can as well as help users to through the virtual environment to interact to the virtual entities knowing through a nature feeling. 3Ds Max is a software to prepare virtual world, which can describe 3D object. Users normally construct virtual world by integrating several(a) media style such as text, picture, and sound and so on. We are using 3Ds Max to build simulate of TAR college. Because 3Ds Max is more expressi ve that a simple 3D scene. It can show campus scenery through the net. Users can virtually manner of walking into campus, feeling the nature entities of campus scene. Besides, users can acquaint him with to each one buildings relative slip and its situation. In every building user can learn by interactive materials. Features like these are very important for those are new and foreign users can also login the net to seek out virtual campus.What is plump for Engine? feisty engines pull up stakes a suite of visual development tools in addition to recyclable software components. These tools are principally provided in an integrated development environment to enable simplified, rapid development of games in a entropy-driven manner. Game Engine provide flexible and reusable software political computer program which provides all the core functionality needed, complexities, to develop a game application while reducing costs, and sequence-to-market.Game engines usually provide syllabus abstraction, allowing the comparable game to be run on non-homogeneous platforms including game consoles and personal computers with few, if all, changes made to the game source code.Some game engines are able to provide real-time 3D make capabilities instead of the wide range of functionality required by games. These types of engines are considered as intenses engine, rendering engine, or 3D engine instead of the more encompassing circumstance game engine. uniformity 3D also considers as a multi-platform game development tool. It is fully object-oriental be after and FPS (First Person Shooter) controller ready to program. Unity 3D consist of API for develop RTS (Real Time Strategy) and FPS type of game genre. well-being of Game EngineGame engines offer several of features and opportunities-Tracking and enter of individuals and their behavior if the world is represented digitally, it can be recorded precisely. security measure features individuals may be prevente d from entering certain parts of the world, in fact, the engine could restrict everything they doVandalism in the real world, reconstructing a pulverise building is essentially impossible whereas in a digital world it is nonDetachment users cannot harm each other physi yelly because they are probably in different parts of the real world, and engulfed in a virtual oneCensorship the engine would be able to stipulate what a certain individual can and cannot see, or what they can and cannot doEmpowering everyone share the same abilities independent of actual physical bring up comeback if we record the world like a video, we could replay it at will, from either place at any time through any view. relation of Game EnginesWith the number of game engines increasing, today game engine provide the most advance features such as complex model, artificial intelligent, graphic engine, as well as networking, sound engine and modification tool. nigh leading game engine found on game ru bric namely Unreal Tournament 3 and Half Life 2 has relatively equal ability in graphic engine, physic engine and development tool. These categories are essential in this research for its visualization and tractability to modification although trammel to game direct only. Unity 3D is not found on game title and can be use to develop new game with game play, game logic and environment.Game Engine for Visualization ToolGame Engine can use to develop various natures of projects. Normally, the game world is built by merchandise its entire object from particular CAD/3D applications such as 3Ds Max. In this case, game engine usually comes with the game itself becomes a platform on which modification is taking place. Modifying game level for architecture visualization purpose is stimulating because it opens up the game engine for real time data rendering and manipulation. Game engines could quickly develop models and deploy it with caryopsis and lighten effect in game engine-based application with no wreak ahead hold on blue-end computer specificationActually a deal out of technical specification on each engine, I had focus on the findings rough primary functions of game engine such as 3D geometry data input/output, lighting and texture interpret. This consideration was taken in general because those base functions are the most significant functions that take advantage from the 3D rendering and vitality software.The summary of this study is depicted by postpone 1. circuit card 1 Summary of game engines for visualization.Engine NameGeometries I/OLightingTexture MappingUnreal Engine 2Built-in editor, any CAD data must(prenominal) be convertedDynamic lighting and shadow, HDR (High Dynamic Range) Rendering3D vegetation generator, shader waySource-Half-Life 2No built-in editor, any CAD data must be convertedDynamic lighting and shadow, HDR (High Dynamic Range) Rendering optimisation for large open areaCryEngineNatively read most of CAD agree format Dynamic lighting and shadow, Time of day lightingHeightmap and polygon reductionGame Engine for Interactivity ToolIn addition to visualization, virtual environment also has provide users with interactive and communication remainss. The virtual environment will only be useful if it supports physically realistic behavior. The types of realistic behaviors depend on the specific application. In architecture and campus be after, usually we beseech realistic representation of spatial environment with naturalistic effect as well as dynamic elements that inhabit it. Moreover, for interactive tool that could invoke spatial awareness and comprehension to further make better be after decision, it is important to consider how user can interact with game objects.In this case, I found that two previous projects are using built-in interactivity tool in game engines. Since interactivity is the element that is not provided by any 3D rendering and animation software, it is prospering to us to use this function to enhance the persona of architecture visualization.Table 2 Summary of game engines for interaction.Engine NameInteractivity functionHalfLife 2Built-in interaction editor, limited only for non-playable objects. Basic navigation provided.RenderwareC++ script to build interaction with objects and users some(prenominal) of these game engines are ease for use. Scripting mechanism is the primary(prenominal) electrical outlet to create the interactivity by using game engine. For use in campus fancy, interaction system is based on the assumption that we can observe, examine as well as explore in 3D in real world whatever objects or entities we want to interact with. This kind of demand may require script programming in differentiate to get high up flexibility and freedom to achieve goals.APPLICATIONSFollowing are some applications that can create by Game Engine-EntertainmentGame engines exist purely for the purpose of romp and entertainment except a colossal in dustry exists around not just the content of the game, but the technology behind them. Innovations because of internet have led to a huge surge for online gaming, where a number of players owning the same game compete head-to-head or with each other in the same game environment. pass on of warAmerican army cadets already use games to practice tank and substructure battles either individually or as teams. Real practice sessions in real tanks are expensive, whereas a game world is easily limit within a few moments. The American government developed a game that would accurately recreate the operations of the U.S. Army, with the intention of signing on new recruits. Battles are fought in a full 3D world between groups of people with an internet connection.Medicine3D games (specifically for gaming) are employ as relaxants if a patient is undergoing a annoyanceful procedure, pre-occupying that patient with a game served by a VR headset can cut their perception of pain in half. The effect is not as significant if the patient is vie in 2D or in a non-immersive world.ExhibitionsDigitalo Studios developed two exhibitions using the Unreal game engine high resolution walkthroughs of the Notre noblewoman and the Florida Everglades National Park. The intent was to replicate the environments and populate them with simple characters. There are many reasons to use a licensed game engine in this context by default, they include a powerful renderer, interactivity and multi-user features. The target platform is identical a standard PC.Impact on 21st ampere-second ClassroomThere are multiple barriers to properly implementing game design into the 21st century classroom. Highlighted below are six primary obstacles which will need to be addressed prior to utilizing game design promiscuously in our collegeNegative perceptions toward video games as educational components. Much of this comes from a lack of understanding of educators of the difference between arcade style v ideo games to more complex role-playing, graphically dense, and cognitively viable modem games.The difficulty of providing state of the art graphics in educational video games. The disciples enthusiasm for gaming may be diminished if the theatrical role of the graphics utilized in the classroom are not equivalent to the graphics they are used to seeing on home consoles.Lack of adequate computing computer hardware in the classrooms to run advanced video games a one-to-one learner computer ratio is not in the near future.A work day divided by unequal class periods which hindered long term engagement in complex games. Researchers must determine if a student is interrupted while in the process of engaging in a learning objective within the gaming environment, do the interruptions interfere in the students learning process? The findings of this research will dictate the type of short activities that could be developed to align with the school day.A lack of real world affordances.A lack of alignment to state standards. Video games pre-aligned to state standards (where they exist) would have an easier time getting into our classrooms.Why Unity 3D?Unity3D is a software application and 3D game development environment. It can call as Game Engine. Unity 3D Game Engine allows users to create immersive, interactive, 3D games and simulations. However, the games and simulations that are created with Unity can be easily vie on Linux and Windows computers, using either a web-browser plug-in, or running a self-contained executable program. Unity consider as GUI based and it can easily to imports 3D models and animation from a variety of 3D design software applications. Compared to many other game engines, Unity is relatively easy to learn, using it can still be used to develop rich and robust games and applications. Finally, Unity allows users to choose from a different of code and scripting languages to program the interactivity and artificial intelligence components o f the game. E.g. C and JavaScript4.2 Visualization TechniquesIn order to achieve graphic performance as appropriate as the most 3D rendering applications, we explored Unity3D capability to handle basic function such as large scale texture mapping and dynamic lighting (see think 5). The main factor taken into consideration is the balance between graphic performance and real-time simulation.Adjusting texture map with orthographic paintingApplying final texture in 3D mesh in Unity3D3D Model in Blender, baked- lighting using ambience occlusion proficiency to render texture map inscribe Procedure of texture mapping and baked-lighting.For such condition, there are two constraints of texture mapping to get under ones skin greater performance both in graphics and game play (see common figs 6 7)1. Texture surface must be as small as possible and visually appropriate.2. Texture must be mold with baked-lighting information to get lighting effect (ambient occlusion) during game play.-ima ge size original 1024 x 1024 pixel-memory consume 652 KB-visual quality high quality, antialiasing, expand relief-image size 512 x 512 pixel-memory consume 170.7 KB-visual quality appropriate quality, nearly no-difference from 1000 x 1000 pixel-image size 256 x 256 pixel-memory consume 42.7 KB-visual quality poor and loose detailFigure Comparison of texture size.The Investigation on utilize Unity3D Game EngineTexture Size and Memory ConsumptionFigure 7 Memory size comparisonsInteraction TechniqueVirtual ingenuousness in game-based environment can categorize into two parts which are game world and game design. Game world consist of game environment and all game objects. Game design consists of game scenario that determines how the game will be played and how the game world would interact with the user or with other game objects.Intention on investigating Unity3D is to explore its ability as a tool for design study, how it different from any other available 3D applications or any 3D viewer and presentation authoring applications and what is the advancement (see Table 4).Therefore before we expand our investigation, we step send with architecture design point of view. We regard game engine as an engine to develop our tool therefore it is important to consider aspects of design study to be incorporated in this application and at the same time investigating the method and technique to accommodate such requirements.Table 4 Game Design and requirementGame DesignUnity3D- based applicationOther applicationscreate 3D environment which visual quality balance with the game performancemaximum visual quality for real world representation, i.e. light and shadow, alpha channel, texture map, time-frame independent animation slight visual quality features (VRML, Flash-based)create system of navigation which allow user to explore with maximum peak of freedomallow maximum degree of freedom to explore and navigate in virtual environmentpre-programmed animation seq uence (3D animation), less flexible freedom of movement (QuickTime VR)view direction, high degree of navigation system (Bentley-3D PDF)create system of navigation which allow user to examine particular object of interest in various way of perspectivesmethod to enhance spatial comprehensionview direction, high degree of navigation system (Bentley-3D PDF)create method to incorporate various type of informationrich content and other data bounding techniquerequire script language and server-based interaction (Flash-based)create method to accommodate flexible 3D data exchangemethod for 3D data interchangeable to external toolless flexible to perform data synchronization (Flash-based and other animation packages)create a method to see conventional analysis studymethod to perform some basic visual-based analysisless flexibleflexibility to expand game designObject-oriented programming4.3.1 NavigationThe navigation system is the main important to be considered in this application. As for a tool to examine 3D world, the main considerations of developing navigation system are1. It must be easy to learn, easy to remember and easy to use with maximum intuitive level as possible.2. It must have rich features on minimum divulge inputAs navigation system is crucial both for geographic expedition and comprehension of 3D environment, we then elaborate the design of navigation system into the following criteriaThere are two main navigation systems tender Eye View (HEV) (First Person Camera) and Bird Eye View (BEV). Both are triggered by cringe stroke on an icon.On each navigation method, instead of using icon-based navigation panel for pan, zoom, orbit and others (see Figure 8), each method has contextual button using mouse- depictboard stroke combination.In BEV zoom using mouse scroll wheel orbit using mouse movement pan using mouse left click and dragFigure Pan, zoom and orbital navigation using mouseIn FPS, we use standard view navigation for FPS game (see Figure 9) s eek and turn using mouse movement walk forward using key w walk backward using key s sloping trough left using key a slide right using key dFigure Turn/look and move toward direction using mouse and keyboard combination.All these navigation system are programmed using Unity3D JavaScript since it does not provide any built-in navigation system as available on previous web-based applications.
