  • The Fondation Louis Vuitton
    THE FONDATION LOUIS VUITTON A new ambition for LVMH's corporate patronage Created by the LVMH group and its Maisons in 2006 on the initiative of Bernard Arnault, the Fondation Louis Vuitton forms part of the art and culture patronage programme developed by the group for over twenty years. It also marks a new step driven by a renewed ambition: – A lasting commitment with the desire to become firmly rooted in a particular place and bring an institution to life over the long term. – A major philanthropic gesture towards the city of Paris with the construction of an exceptional building on municipal state property and the signature of a 55-year occupancy agreement with Paris city council. Driven by a desire to work for the common good, the Fondation Louis Vuitton demonstrates a clear commitment to contemporary art and looks to make it accessible to as many people as possible. To foster the creation of contemporary art on a national and international scale, the Fondation Louis Vuitton calls on a permanent collection, commissions from artists, temporary modern and contemporary art exhibitions and multidisciplinary events. One of its priorities is to fulfil an educational role, especially among the young. A new monument for Paris Frank Gehry has designed a building that, through its strength and singularity, represents the first artistic step on the part of the Fondation Louis Vuitton. This large vessel covered in twelve glass sails, situated in the Bois de Boulogne, on the edge of avenue du Mahatma Gandhi, is attached to the Jardin d'Acclimatation. Set on a water garden created for the occasion, the building blends into the natural environment, amidst the wood and the garden, playing with light and mirror effects.

    Piia Brusi MAKING A GAME CHARACTER MOVE Animation and motion capture for video games Bachelor’s thesis Degree programme in Game Design 2021 Author (authors) Degree title Time Piia Brusi Bachelor of Culture May 2021 and Arts Thesis title 69 pages Making a game character move Animation and motion capture for video games Commissioned by South Eastern Finland University of Applied Sciences Supervisor Marko Siitonen Abstract The purpose of this thesis was to serve as an introduction and overview of video game animation; how the interactive nature of games differentiates game animation from cinematic animation, what the process of producing game animations is like, what goes into making good game animations and what animation methods and tools are available. The thesis briefly covered other game design principles most relevant to game animators: game design, character design, modelling and rigging and how they relate to game animation. The text mainly focused on animation theory and practices based on commentary and viewpoints provided by industry professionals. Additionally, the thesis described various 3D animation and motion capture systems and software in detail, including how motion capture footage is shot and processed for games. The thesis ended on a step-by-step description of the author’s motion capture cleanup project, where a jog loop was created out of raw motion capture data. As the topic of game animation is vast, the thesis could not cover topics such as facial motion capture and procedural animation in detail. Technologies such as motion matching, machine learning and range imaging were also suggested as topics worth covering in the future.

  • Blender Instructions a Summary
    BLENDER INSTRUCTIONS A SUMMARY Attention all Mac users The first step for all Mac users who don’t have a three button mouse and/or a thumb wheel on the mouse is: 1.! Go under Edit menu 2.! Choose Preferences 3.! Click the Input tab 4.! Make sure there is a tick in the check boxes for “Emulate 3 Button Mouse” and “Continuous Grab”. 5.! Click the “Save As Default” button. This will allow you to navigate 3D space and move objects with a trackpad or one-mouse button and the keyboard. Also, if you prefer (but not critical as you do have the View menu to perform the same functions), you can emulate the numpad (the extra numbers on the right of extended keyboard devices). It means the numbers across the top of the standard keyboard will function the same way as the numpad. 1.! Go under Edit menu 2.! Choose Preferences 3. Click the Input tab 4.! Make sure there is a tick in the check box for “Emulate Numpad”. 5.! Click the “Save As Default” button. BLENDER BASIC SHORTCUT KEYS OBJECT MODE SHORTCUT KEYS EDIT MODE SHORTCUT KEYS The Interface The interface of Blender (version 2.8 and higher), is comprised of: 1. The Viewport This is the 3D scene showing you a default 3D object called a cube and a large mesh-like grid called the plane for helping you to visualize the X, Y and Z directions in space. And to save time, in Blender 2.8, the camera (left) and light (right in the distance) has been added to the viewport as default.

  • 'Building' Architects and Use of Open-Source Tools Towards Achievement of Millennium Development Goals
    'Building' Architects and Use of Open-source Tools Towards Achievement of Millennium Development Goals. Oku, Onyeibo Chidozie Department of Architecture Faculty of Environmental Sciences Enugu State University of Science and Technology Email: [email protected] ABSTRACT Millennium Development Goals (MDGs) were established by the United Nations to improve the well-being of humans and their habitat. Whether they are the target beneficiaries or amongst the parties administering services for achieving the MDGs, humans must carry out these activities in a physical environment. Hence, the Seventh Goal of the MDG has an indirect and far-reaching relationship with the others because it deals with the sustainable development of the built environment. Architects deliver consultancy services that span the design, documentation and construction supervision of the built environment. This study sought to determine the extent to which these professionals can do this, with respect to the Seventh Millennium Development Goal, using mainly open-source tools. The study draws from literature reviews, end-user feedback or reports, interviews with developers of applicable open-source products, and statistics from a survey, launched in 2011, for capturing how architects use ICT in their businesses. Analysis of popular open-source technologies for the Architecture, Engineering and Construction (AEC) industry show a concentration of resources in favour of the later stages of the Architect's role, rather than the design and contract-drawing stages. Some of the better-implemented tools are either too cryptic for professionals who communicate in graphical terms, or heavily biased towards software engineering practices. The products that promise Building Information Modelling (BIM) capabilities are still at an early developmental stage.

  • A Procedural Interface Wrapper for Houdini Engine in Autodesk Maya
    A PROCEDURAL INTERFACE WRAPPER FOR HOUDINI ENGINE IN AUTODESK MAYA A Thesis by BENJAMIN ROBERT HOUSE Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Chair of Committee, André Thomas Committee Members, John Keyser Ergun Akleman Head of Department, Tim McLaughlin May 2019 Major Subject: Visualization Copyright 2019 Benjamin Robert House ABSTRACT Game development studios are facing an ever-growing pressure to deliver quality content in greater quantities, making the automation of as many tasks as possible an important aspect of modern video game development. This has led to the growing popularity of integrating procedural workflows such as those offered by SideFX Software’s Houdini FX into the already established de- velopment pipelines. However, the current limitations of the Houdini Engine plugin for Autodesk Maya often require developers to take extra steps when creating tools to speed up development using Houdini. This hinders the workflow for developers, who have to design their Houdini Digi- tal Asset (HDA) tools around the limitations of the Houdini Engine plugin. Furthermore, because of the implementation of the HDA’s parameter display in Maya’s Attribute Editor when using the Houdini Engine Plugin, artists can easily be overloaded with too much information which can in turn hinder the workflow of any artists who are using the HDA. The limitations of an HDA used in the Houdini Engine Plugin in Maya as a tool that is intended to improve workflow can actually frustrate and confuse the user, ultimately causing more harm than good.

  • Efficient Rendering of Caustics with Streamed Photon Mapping
    BULLETIN OF THE POLISH ACADEMY OF SCIENCES TECHNICAL SCIENCES, Vol. 65, No. 3, 2017 DOI: 10.1515/bpasts-2017-0040 Efficient rendering of caustics with streamed photon mapping K. GUZEK and P. NAPIERALSKI* Institute of Information Technology, Lodz University of Technology, 215 Wolczanska St., 90-924 Lodz, Poland Abstract. In this paper, we present the streamed photon mapping method for enhancing the rendering of caustics. In order to achieve a realistic caustic effect, global illumination methods require additional data, which are gathered by creating a caustic map or increasing the number of samples used for rendering. Our method employs a stream of photons with a varying luminance level depending on the material properties of the surface. The application of a concentrated photon stream provides the ability to render caustics effectively without increasing the number of photons in a photon map. Such an approach increases visibility of results, while also allowing for faster computations. Key words: rendering, global illumination, photon mapping, caustics. 1. Introduction 2.

  • Extending Capabilities of Bim to Support Performance Based Design
    www.itcon.org - Journal of Information Technology in Construction - ISSN 1874-4753 EXTENDING CAPABILITIES OF BIM TO SUPPORT PERFORMANCE BASED DESIGN SUBMITTED: January 2017 REVISED: October 2017 PUBLISHED: February 2018 at https://www.itcon.org/2018/2 EDITOR: Amor R. Nusrat Jung, M.Sc.,* VTT Technical Research Centre of Finland and Department of Mechanical Engineering, Aalto University, [email protected]; [email protected] Tarja Häkkinen, PhD., VTT Technical Research Centre of Finland [email protected] Mirkka Rekola, M.Sc., Senate Properties [email protected] SUMMARY: As we advance towards high-performance buildings, it is becoming necessary to reinforce and extend the role of building information modelling (BIM) to better support performance-based design. To achieve an optimally functioning building that fulfils the need of the end-user and is designed in an environmentally conscious manner necessitates considering energy performance, environmental performance, indoor air quality, lighting, and acoustics. To consider these multiple criteria, use of computer-based modelling tools and comprehensive simulation methods becomes essential. These criteria are typically assessed after the main phases of architectural design of the building, and the knowledge is passed on to the engineers for development of the technical design. During the technical design process, the exchange of data between the design model and a selected building performance aspect may occur. This paper investigates the potential of BIM-based models at the core of providing input data required for performance-based simulations (BPS) to enable iterative multi-criteria assessment towards high performance buildings. A comprehensive literature review of 249 documents was conducted to identify the current state of knowledge and provide future directions for design and simulation tools to better quantify and evaluate the performance aspects.
