Craft Physics Interface

Hansson, Henrik January 2007 (has links)
<p>This is a masters thesis (20p) in computer science at the University of Linköping. This thesis will give an introduction to what a physics engine is and what it consist of. It will put some engines under the magnifying glass and test them in a couple of runtime tests. Two cutting edge commercial physics engines have been examined, trying to predict the future of physics engines. From the research and test results, an interface for physics engine independency has been implemented for a company called Craft Animations in Gothenburg, Sweden.</p>

Hybrid Mobile Robot System: Interchanging Locomotion and Manipulation

Ben-Tzvi, Pinhas 30 July 2008 (has links)
This thesis presents a novel design paradigm of mobile robots: the Hybrid Mobile Robot system. It consists of a combination of parallel and serially connected links resulting in a hybrid mechanism that includes a mobile robot platform for locomotion and a manipulator arm for manipulation, both interchangeable functionally. All state-of-the-art mobile robots have a separate manipulator arm module attached on top of the mobile platform. The platform provides mobility and the arm provides manipulation. Unlike them, the new design has the ability to interchangeably provide locomotion and manipulation capability, both simultaneously. This was accomplished by integrating the locomotion platform and the manipulator arm as one entity rather than two separate and attached modules. The manipulator arm can be used as part of the locomotion platform and vice versa. This paradigm significantly enhances functionality. The new mechanical design was analyzed with a virtual prototype that was developed with MSC Adams Software. Simulations were used to study the robot’s enhanced mobility through animations of challenging tasks. Moreover, the simulations were used to select nominal robot parameters that would maximize the arm’s payload capacity, and provide for locomotion over unstructured terrains and obstacles, such as stairs, ditches and ramps. The hybrid mobile robot also includes a new control architecture based on embedded on-board wireless communication network between the robot’s links and modules such as the actuators and sensors. This results in a modular control architecture since no cable connections are used between the actuators and sensors in each of the robot links. This approach increases the functionality of the mobile robot also by providing continuous rotation of each link constituting the robot. The hybrid mobile robot’s novel locomotion and manipulation capabilities were successfully experimented using a complete physical prototype. The experiments provided test results that support the hypothesis on the qualitative and quantitative performance of the mobile robot in terms of its superior mobility, manipulation, dexterity, and ability to perform very challenging tasks. The robot was tested on an obstacle course consisting of various test rigs including man–made and natural obstructions that represent the natural environments the robot is expected to operate on.

The chimaera project: an online database of animal motions

Gele, Julie Katherine 15 May 2009 (has links)
Digital animators will save vast amounts of project time by starting with a completed skeleton and some base animations. This result can be accomplished with Web 2.0 technologies by creating a repository of skeletons and animations that any animator may use for free. While free Maya™ skeletons currently exist on the Internet, the websites housing them have only brief features and functions for browsing and interacting with these files. None of these websites contain downloadable animations for the provided skeletons. The Chimaera Project improves the field of Web 2.0 sites offering free rigs by offering many new features and freedoms to the animation community. Users may upload and download Maya™ skeletons, share comments and tips with each other, upload animations associated with the skeletons, and search or browse the skeletons in a variety of ways. The skeletons include descriptions and information provided by the creator and are categorized by class, order, and species. Users may access a freely provided script called “zooXferAnim” to import and export animations into text files to be uploaded and downloaded on the website. Many animations per skeleton may be uploaded. The Chimaera Project extends the Web 2.0 community by creating an interactive resource for animators to contribute and share content in a better, more organized format than previously seen on the Internet.

Výkonnostní testy pro chytré TV, set-top boxy a herní konzole / Performance Benchmark for Smart TV Platforms, Set-Top Boxes and Game Consoles

Madaj, Tomáš January 2018 (has links)
Cílem této práce je vytvořit nástroj pro vývoj aplikací  na určité minoritní platformy, primárně Smart TV a HbbTV. Ty jsou implementovány v klienském JavaScriptu. Cílovou skupinou jsou tedy vývojáři takových aplikací, nikoli koncoví uživatelé. Zmíněný nástroj bude mít za cíl zjednodušit a urychlit vývojové procesy, hlavně ladění výkonu aplikací.

Webová aplikace pro grafickou vizualizaci geografických časových řad / Web Application for Graphical Visualization of Geospatial Time Series

Rykala, Kryštof January 2021 (has links)
Geografická data se stala nedílnou součástí každodenního života. Nejběžnější vizualizací geografických dat je statická tematická mapa. Ta ovšem vizualizuje pouze jeden časový okamžik, případně několik z nich, agregovaných dohromady. Bez času navíc není možné vizualizovat geografické jevy, jako je vývoj různých geografických charakteristik (např. růst emisí uhlíku nebo šíření viru). Cílem této práce je vytvoření nástroje pro vytváření vizualizací geografických časových řad, které umožní data prezentovat a studovat. Řešení je vyvinuto jako nástroj aplikace Geovisto. Vyvinutý nástroj umožňuje uživatelům vytvářet vlastní vizualizace a animace geografických časových řad a zároveň je konfigurovatelný pro použití s obecnými daty. Uživatelé se znalostí programování mohou vytvářet nové Geovisto nástroje (např. tematické mapy) a pomocí nástroje pro práci s časem sami implementovat animace do nových tematických map.

Exploring the performance gap: How animation implementation affects the CPU and RAM usage in mobile applications : Among cross-platform and native development approaches

Ametova, Sabina, Lindström, Tim January 2023 (has links)
Mobile applications are a critical part of everyday life. Animations in mobile applications demand optimized performance, which developers are persistently striving to achieve. This study examines the performance of mobile applications developed using native approaches for iOS and Android, as well as the Flutter framework for cross-platform approach, while executing animations. This was motivated by the fact that while cross-platform development offers advantages in terms of development efficiency, it often results in decreased performance. Since the field of mobile development is continuously evolving, it is important to explore new capabilities of mobile technologies. The purpose of this study is to understand the differences in CPU and RAM usage between native and cross-platform applications by examining two types of animation implementations, thereby aiming to identify the causes of the performance gap and propose solutions to decrease the performance gap. This study involved experiments, a literature study and an analysis of the results to address the research questions and fulfill the purpose. The findings of this study showed that the cross-platform approach resulted in higher CPU and RAM usage than the native approaches. However, the performance gap was less noticeable in one of the animation implementations. Thus indicating that the performance of mobile applications can be significantly influenced by the choice of animation implementation. Therefore, a strategic approach to mitigating the performance gap could involve careful selection of Flutter widgets or the incorporation of efficient libraries.
