Learning of the Object Oriented Paradigm Through Interactive Video-Games Development

The Object Orientation Paradigm (OOP) is more than Object Oriented languages. Learning the syntax of a language as C++ or Java is a relatively easy task compared with the understanding of the principles of OO Modeling and Design (OOD), which require a high ability of abstract reasoning. Moreover, it is not enough to teach the artifacts of Computer Aided Software Engineering (CASE) as the Unified Modeling Language (UML) if those principles are not properly understood. We wanted to engage the students in a motivating framework, so both the principles of OOD are properly acquired and put in practice with CASE and programming tools

Player identification in American McGee’s Alice : a comparative perspective

In this paper I analyse personal identification in three incarnations of Alice in Wonderland: the original novels, the 1950s Disney animation film and the computer game American McGee’s Alice. After presenting the research corpus, I lay out the analytical framework derived from Kendall Walton’s theory of representational artefacts as props for evoking imagining in games of make-believe. From this perspective, the Alice heritage relies on spectacle rather than plot to entertain. This spectacle differs across media as each medium’s strengths are played out: language-play in the novels, colour/motion/sound in the film and challenges in the game. There are two types of imagining involved: objective, whereby a person imagines a scene outside of himself, and subjective, in which case the imagining revolves around a version of himself. Both the novels and the film primarily evoke objective imagining whereas the game invites the player to be introjected into the Alice character evoking subjective imagining. The picture is not unambiguous, however, as the novels and the film stage a broad array of subjectifying techniques and the game objectifying ones. This gives us some indication as to the nature of representation which, to be of interest, presents a tension between here and there, between the self and an other

Developing an Open-Source Lightweight Game Engine with DNN Support

With the growth of artificial intelligence and deep learning technology, we have many active research works to apply the related techniques in various fields. To test and apply the latest machine learning techniques in gaming, it will be very useful to have a light-weight game engine for quick prototyping. Our game engine is implemented in a cost-effective way, in comparison to well-known commercial proprietary game engines, by utilizing open source products. Due to its simple internal architecture, our game engine is especially beneficial for modifying and reviewing the new functions through quick and repetitive tests. In addition, the game engine has a DNN (deep neural network) module, with which the proposed game engine can apply deep learning techniques to the game features, through applying deep learning algorithms in real-time. Our DNN module uses a simple C++ function interface, rather than additional programming languages and/or scripts. This simplicity enables us to apply machine learning techniques more efficiently and casually to the game applications. We also found some technical issues during our development with open sources. These issues mostly occurred while integrating various open source products into a single game engine. We present details of these technical issues and our solution

Games technology: console architectures, game engines and invisible interaction

This presentation will look at three core developments in games technology. First we will look at the architectural foundations on which the consoles are built to deliver games performance. Millions of consoles are sold and the console performance is improving in parallel. Next we look at the cutting edge features available in game engines. Middleware software, namely game engines, help developers build games with rich features and also simultaneously harness the power of the game consoles to satisfy gamers. The third part focuses on Invisible Game Interaction. The Nintendo Wii games console was an instant success because of the Wiimote. Old and young alike embraced it. The Microsoft Kinect pushed the boundary even further, where the interaction device is slowly becoming invisible and the human body becomes the interface. Finally, we look at novel research developments that go beyond current game interaction devices

Applications of CSP solving in computer games (camera control)

While camera control systems of commercial 3D games have improved greatly in recent years, they are not as fully developed as are other game components such as graphics and physics engines. Bourne and Sattar (2006) have proposed a reactive constraint based third person perspective camera control system. We have extended the capability of their system to handle occlusion while following the main character, and have used camera cuts to find appropriate camera positions for a few difficult situations. We have developed a reactive constraint based third person perspective chase camera control system to follow a character in a 3D environment. The camera follows the character from (near) optimal positions defined by a camera profile. The desired values of the height and distance constraints of the camera profile are changed appropriately whenever the character enters a semi-enclosed or an enclosed area, and the desired value of the orientation constraint of the camera profile is changed incrementally whenever theoptimal camera view is obstructed. Camera cuts are used whenever the main character backs up to a wall or any other obstructions, or comes out of a semi-enclosed or an enclosed area. Two auxiliary cameras to observe the main camera positions from top and side views have been added. The chase camera control system achieved real-time performance while following the main character in a typical 3D environment, and maintained an optimal view based on a user specified/selected camera profile

Game design and development

The project focuses on computer tools suitable for particular game genres and how they are used to develop 3D computer games. As part of learning about the tools, the author developed a 3D computer adventure game called Adventures of Smiley using Macromedia Director MX and 3D Studio Max. The game\u27s purpose is to engage children using a friendly interface while they learn about different topics in various subject areas through lessons and puzzles. The research gathered information about the current game industry, technologies and game genres, which can be used as a reference for the beginning level game programmer. The project documentation and the game are also published on the Internet and can be freely accessed online

3D animation visualization on commercial websites

3D technology became more and more a part of our live. Often we even don’t know it. 3D technology can be found back in medical applications, cinematographic, automotive design, etc... Only one technology seems to have missed the 3D train, namely the World Wide Web. Internet is still not overwhelmed with 3D content, still and animated. This project analyses the reasons, bottlenecks why 3D technology is so slow in conquering the World Wide Web. The research is focused on 3D visualization in commercial websites. Research is done after the difficulties to include 3D content in a HTML environment. By involving a complete website solution, the ISPN-system, a realistic and immersive environment is setup to research where and what kind of issues may occur. The development of the ISPN-system could be a case on his own eventual done in another Msc project or a PhD project. Main goal of the ISPN-system is to provide decent footage material (visual and data) to graphic designers and website developers. An inquiry will be conducted whether this has some sense

A Performance Comparison of VMware GPU Virtualization Techniques in Cloud Gaming

Cloud gaming is an application deployment scenario which runs an interactive gaming application remotely in a cloud according to the commands received from a thin client and streams the scenes as a video sequence back to the client over the Internet, and it is of interest to both research community and industry. The academic community has developed some open-source cloud gaming systems such as GamingAnywhere for research study, while some industrial pioneers such as Onlive and Gaikai have succeeded in gaining a large user base in the cloud gaming market. Graphical Processing Unit (GPU) virtualization plays an important role in such an environment as it is a critical component that allows virtual machines to run 3D applications with performance guarantees. Currently, GPU pass-through and GPU sharing are the two main techniques of GPU virtualization. The former enables a single virtual machine to access a physical GPU directly and exclusively, while the latter makes a physical GPU shareable by multiple virtual machines. VMware Inc., one of the most popular virtualization solution vendors, has provided concrete implementations of GPU pass-through and GPU sharing. In particular, it provides a GPU pass-through solution called Virtual Dedicated Graphics Acceleration (vDGA) and a GPU-sharing solution called Virtual Shared Graphics Acceleration (vSGA). Moreover, VMware Inc. recently claimed it realized another GPU sharing solution called vGPU. Nevertheless, the feasibility and performance of these solutions in cloud gaming has not been studied yet. In this work, an experimental study is conducted to evaluate the feasibility and performance of GPU pass-through and GPU sharing solutions offered by VMware in cloud gaming scenarios. The primary results confirm that vDGA and vGPU techniques can fit the demands of cloud gaming. In particular, these two solutions achieved good performance in the tested graphics card benchmarks, and gained acceptable image quality and response delay for the tested games

Intelligent Cinematic Camera Control for Real-Time Graphics Applications

E-sports is currently estimated to be a billion dollar industry which is only growing in size from year to year. However the cinematography of spectated games leaves much to be desired. In most cases, the spectator either gets to control their own freely-moving camera or they get to see the view that a specific player sees. This thesis presents a system for the generation of cinematically-pleasing views for spectating real-time graphics applications. A custom real-time engine has been built to demonstrate the effect of this system on several different game modes with varying visual cinematic constraints, such as the rule of thirds. To create the cinematic views, we encode cinematic rules as cost functions that are fed into a non-linear least squares solver. These cost functions rely on the geometry of the scene, minimizing residuals based on the 3D positions and 2D reprojections of the geometry. The final cinematic view is found by altering camera position and angle until a local minimum is met. The system was evaluated by comparing video output from a traditional rigidly constrained camera and the results of our algorithm’s optimally solved views. User surveys are then used to qualitatively evaluate the system. The results of these surveys do not statistically find a preference between the cinematic views and the rigidly constrained views. In addition, we present performance and timing considerations for the system, reporting that the system can operate within modern expectations of latency when enough constraints are placed on the non-linear least squares solver
