Comparing and Evaluating Real Time Character Engines for Virtual Environments

As animated characters increasingly become vital parts of virtual environments, then the engines that drive these characters increasingly become vital parts of virtual environment software. This paper gives an overview of the state of the art in character engines, and proposes a taxonomy of the features that are commonly found in them. This taxonomy can be used as a tool for comparison and evaluation of different engines. In order to demonstrate this we use it to compare three engines. The first is Cal3D, the most commonly used open source engine. We also introduce two engines created by the authors, Piavca and HALCA. The paper ends with a brief discussion of some other popular engines

Real time physics-based augmented fitting room using time-of-flight cameras

Ankara : The Department of Computer Engineering and the Graduate School of Engineering and Science of Bilkent University, 2013.Thesis (Master's) -- Bilkent University, 2013.Includes bibliographical references leaves 63-72.This thesis proposes a framework for a real-time physically-based augmented cloth tting environment. The required 3D meshes for the human avatar and apparels are modeled with speci c constraints. The models are then animated in real-time using input from a user tracked by a depth sensor. A set of motion lters are introduced in order to improve the quality of the simulation. The physical e ects such as inertia, external and forces and collision are imposed on the apparel meshes. The avatar and the apparels can be customized according to the user. The system runs in real-time on a high-end consumer PC with realistic rendering results.Gültepe, UmutM.S

Support tools for 3D game creation

Nowadays, tools for developing videogames are a very important part of the development process in the game industry. Such tools are used to assist game developers in their tasks, allowing them to create functional games while writing a few lines of code. For example, these tools allow the users to import the content for the game, set the game logic, or produce the source code and compile it. There are several tasks and components regarding the development of videogames that may become unproductive, therefore, it’s necessary to automate and/or optimize such tasks. For example, the programming of events or dialogs can be a task that consumes too much time in the development cycle, and a tedious and repetitive task for the programmer. For this reason, the use of tools to support these tasks can be very important to increase productivity and help on the maintenance of the various processes that involve the development of videogames. This dissertation aims to demonstrate the advantages of the use of these kind of tools during the development of videogames, presenting a case study involving the development of a Serious Game entitled Clean World.Atualmente, as ferramentas para o desenvolvimento de jogos são uma parte bastante importante de todo o processo de desenvolvimento. Estas ferramentas servem para assistir os criadores de jogos nas tarefas que realizam, permitindo-lhes a criação de jogos funcionais escrevendo poucas linhas de código. Desenvolver um videojogo sem a utilização de ferramentas especializadas é um processo complexo e que consome bastante tempo, daí a existência de ferramentas que permitem ao utilizador importar os conteúdos para o jogo, definir a lógica de jogo, produzir o código fonte e compilá-lo. Este tipo de software é normalmente utilizado por quem se dedica à criação de jogos como hobby, ou por profissionais que procuram otimizar o processo de desenvolvimento de jogos. Existem várias componentes ao nível do desenvolvimento de videojogos que se tornam pouco produtivas, se não forem automatizados e/ou otimizadas. Por exemplo, a programação de eventos ou de diálogos pode ser uma tarefa que consome demasiado tempo no ciclo de desenvolvimento, para além de ser uma tarefa entediante e repetitiva no ponto de vista do programador. Por este motivo, a utilização de ferramentas pode ser muito importante no que diz respeito ao aumento da produtividade e manutenção dos vários processos que envolvem o desenvolvimento de videojogos. Nesta dissertação pretendemos demonstrar as vantagens da utilização dessas mesmas ferramentas durante o desenvolvimento de videojogos, através da apresentação de um caso de estudo que envolve o desenvolvimento de um Serious Game intitulado Clean World. Em Clean World, foram identificadas determinadas tarefas que se mostraram demasiado repetitivas e entediantes quando programadas por inteiro, como é o caso da adição, modificação ou remoção de componentes como diálogos, quest ou items. Tendo em conta este problema concreto, foram criadas algumas ferramentas de forma a aumentar a produtividade no desenvolvimento do jogo, tornando tarefas repetitivas e entediantes em processos simples e intuitivos. O conjunto de ferramentas é constituído por: Item Manager, Quest Manager, Dialog Manager e Terrain Creator

Scare Tactics

It is the purpose of this document to describe the design and development processes of Scare Tactics. The game will be discussed in further detail as it relates to several areas, such as market analysis, development process, game design, technical design, and each team members’ individual area of background research. The research areas include asymmetrical game design, level design, game engine architecture, real-time graphics, user interface design, networking and artificial intelligence. As part of the team’s market analysis, other games featuring asymmetric gameplay are discussed. The games described in this section serve as inspirations for asymmetric game design. Some of these games implement mechanics that the team seeks to emulate and expand upon in Scare Tactics. As part of the team’s development process, several concepts were prototyped over the course of two months. During that process the team adopted an Agile methodology in order to assist with scheduling, communication and resource management. Eventually, the team chose to expand upon the prototype that became the basis of Scare Tactics. Game design and technical design occur concurrently in the development of Scare Tactics. Designers conduct discussions where themes, settings, and mechanics are conceived and documented. Mechanics are prototyped in Unity and eventually ported to a proprietary engine developed by our team. Throughout the course of development, each team member has had to own an area of design or development. This has led to individual research performed in several areas, which will be discussed further in this document

Scalable Real-Time Rendering for Extremely Complex 3D Environments Using Multiple GPUs

In 3D visualization, real-time rendering of high-quality meshes in complex 3D environments is still one of the major challenges in computer graphics. New data acquisition techniques like 3D modeling and scanning have drastically increased the requirement for more complex models and the demand for higher display resolutions in recent years. Most of the existing acceleration techniques using a single GPU for rendering suffer from the limited GPU memory budget, the time-consuming sequential executions, and the finite display resolution. Recently, people have started building commodity workstations with multiple GPUs and multiple displays. As a result, more GPU memory is available across a distributed cluster of GPUs, more computational power is provided throughout the combination of multiple GPUs, and a higher display resolution can be achieved by connecting each GPU to a display monitor (resulting in a tiled large display configuration). However, using a multi-GPU workstation may not always give the desired rendering performance due to the imbalanced rendering workloads among GPUs and overheads caused by inter-GPU communication. In this dissertation, I contribute a multi-GPU multi-display parallel rendering approach for complex 3D environments. The approach has the capability to support a high-performance and high-quality rendering of static and dynamic 3D environments. A novel parallel load balancing algorithm is developed based on a screen partitioning strategy to dynamically balance the number of vertices and triangles rendered by each GPU. The overhead of inter-GPU communication is minimized by transferring only a small amount of image pixels rather than chunks of 3D primitives with a novel frame exchanging algorithm. The state-of-the-art parallel mesh simplification and GPU out-of-core techniques are integrated into the multi-GPU multi-display system to accelerate the rendering process
