Abstract :"This thesis is a research project on the similarities and difference in 3D modeling and op- timizations for different sectors of multimedia. The purpose of this project is to analyse three different areas , an d carry out a project for practical comparison purpose s with the creation of a 3D model using different methods of modeling and optimization . The methods used in this project is a workflow step by step process of production , for later comparison and analysis. The result of this project was the creation of an optimized model for game production, the methods used at modeling pipeline and the comparison between different sectors of Mul- timedia illustrate the similarities and di fferen ces in modeling optimization between these sectors. This project is created to illustrate paths taken for modeling optimization in the biggest sectors of 3D production, with comparative results and analysis. "

Abstract: "This thesis aims to study the design possibilities for supporting explorative form-finding in 3D modeling applications. For today's many design professions, 3D forms are achieved partly in engagement with digital environments. Use of software has far exceeded final idea execution, extending to the early phases of design work in which the outcome is not predetermined. This insight led designers of interactive systems support sketching and ideating activities by reducing the risk of experimentation and cognitive effort demanded from user. Yet, there has been less emphasis on traditional design and craft practice that acknowledges engagement with materials and effort spent on work as an integral part of creative process. The notion of exploration in the scope of this thesis attempts to incorporate such aspects. Relevant literature about workshop practice in design and craft has been reviewed, as well as examples of CAD technologies that aid designers. In this light, HCI perspectives on the design of creativity support tools and games have been discussed. The thesis work aimed to concretize this background by building a design strategy and an interactive artifact. A 3D form-finding application concept using objects in modeling space to indirectly manipulate geometry, "kfields", has been developed and evaluated with users at various stages. The thesis concludes by reflecting on the findings of different design stages and proposing further directions for design. Keywords: 3D Modeling, CAD, digital material, form"

Abstract: "Serious Games are increasingly used as a tool for various applications contrary to the traditional enterta inment purpose. Many game engines are available, and Unity3D is another example that presents some features such as rapid prototyping and an easy learning curve. The 3D space where action takes place is sometimes hard to map into a logical memory structure providing flexible access to that information. The problem of tracking players ' path as well as their decision s in 3D environments arises when there is no previous knowledge of the scenario representation and the creation of a memory data structure poses an extra effort for the modeller. The proposed solution in this paper, albeit simple, is a straightforward way to track the location of the video game character and map it when he / she passes certain limits. Th is mechanism proved to represent a key step for ward, addressing the important issue of tracking the decision - making process of players for future analysis and behaviour elicitation."

"Objects in 3D games are typically shell models, a polygon mesh representing the shell or skin of the object. While emulation of the behaviour of shell models under combustion is sucient for many game applications and is fairly well studied, solid objects do in fact burn rather dierently than shell objects. We show how to manipulate shell models so that they appear to burn as solid models. Since our burning objects will be only a small part of a video game, computation speed is of the essence. We demonstrate that our method uses only a fraction of the computational power available by implementing the computation on a modest GPU using CUDA."

"Automated lm editing involves the generation of the position, orientation, motion and selection of virtual cameras in interactive 3D graphics applications. There is a pressing demand for techniques to assist and automate the control of virtual cameras in the computer games industry where the rapid development of personal computers and high performance consoles has led to substantial improvements in the visual delity of games. The goal of this survey is to characterize the spectrum of applications that require automated lm editing, present a summary of state-of-the-art models and techniques, and identify both promising avenues and hot topics for future research"

Abstract: "This paper explores the consequences of using the game engine Unity to construct 3-D models of Pompeian houses, linked to art and spatial databases, as an ongoing research colloquium for advanced undergraduate and graduate students in the humanities. Rather than serving as a neutral piece of visualization software, the game engine functions as critical tool because, more than any other visualization platform, it permits real time, embodied movement through the houses. One outcome of such embodied movement has been the recognition that the traditional vocabulary for describing space in Pompeii is inadequate, and a much more careful methodology is required, using network topology and visibility graph analysis to establish spatial profiles for the rooms. As they construct the models in Unity, students also encounter the contradiction between the texture pipeline used to produce immersion in games and the emphasis on accuracy and scientific objectivity found in cultural heritage discourse, a discourse which paradoxically also stresses immersion. Finally, the game engine encourages students to consider the rhetoric of embodied play in the Pompeian decorative ensembles themselves."

"The evacuation of complex buildings is a challenge under any circumstances. Fire drills are a way of training and validating evacuation plans. However, sometimes these plans are not taken seriously by their participants. It is also difficult to have the financial and time resources required. In this scenario, serious games can be used as a tool for training, planning and evaluating emergency plans. In this paper a prototype of a serious games evacuation simulator is presented. To make the environment as realistic as possible, 3D models were made using Blender and loaded onto Unity3D, a popular game engine. This framework provided us with the appropriate simulation environment. Some experiences were made and results show that this tool has potential for practitioners and planners to use it for training building occupants."
