Research ContextThis enquiry will use three female subjects to examine how an artist might creatively engage with advances in 3D scanning, 3D software applications and 3D rapid printing to achieve a 3D portrait/self-portrait. It will consider whether contemporary body scanning tools can facilitate the capture of a natural stance or dynamic pose, to reveal the emotional states of each female character. Pilot body scans I undertook in Huddersfield, London and Glasgow, suggest that body scanning has the potential to reveal both an inner and outer self. However, current body scanning systems are devised to extract accurate body measurements, which means that the scanning booths and the software that they use have a very narrow focus. To guarantee 'good' data a subject must stand motionless, adopting a pre-defined pose. This is because a number of human factors can adversely affect the scanning process and data collection. These include problems with skin translucency, hair, shadowing and unwanted motion. Aims & ObjectivesThe enquiry will use the TriForm BodyShape Scanner from Wicks and Wilson to capture the female subject in three dimensions. This white light technology is safe and in the pilot tests I undertook it provided the most accurate data. Each female subject will test this technology as a system for capturing mood and gesture. Each scan will create a three-dimensional map containing 1.5 million coordinate points (cloud data), ready for use in 3D software packages. In order to fully develop the potential of each portrait, I will carefully study the cloud data portraits. Traditionally this data is viewed, analysed and cleaned to remove any unwanted information, but I am keen to enhance the portrait using artistic knowledge and intuition. In attempting to reveal both inner and outer aspects of feminine identity I aim to transform the captured data with the assistance of Dr. Unver, a 3D scanning and software specialist based within the Department of Creative Technologies at the University of Huddersfield. This manipulation will take many forms: unwanted movement might be digitally sculpted to reveal gesture; a particular stance or pose that has been adopted might be exaggerated to create a new dramatic emphasis; additional 3D wire frame props might be incorporated to expand the visual narrative of the portrait and suggest emotional states.Through this process I aim to examine whether free and expressive techniques associated with portrait and self-portrait sculpture can be developed digitally in 3D software environments. How does sculpting data differ from sculpting physical materials? Can an intimate process evolve where the traditional sense of touch is recorded by a mouse movement? What possibilities might the digital 3D environment offer to supersede traditional sculpting methodologies? A selection of the modified portraits/self-portraits will be constructed using new Rapid Prototyping technologies. An important objective of the process is to discover how different rapid prototyping procedures and materials will affect the production and construction of the 3D portraits/self-portraits. This enquiry is process driven and will evolve and develop with time. Advisors and peer groups will contribute to the process at identified points. Processes will be repeated, allowing new discoveries to inform future methodologies and working practices to respond to an expanding knowledge base. Potential applications and benefits:Methodologies will be recorded and documentation will be made available via a website/blog. An authored article will be written in a peer-reviewed journal.An academic paper presenting research methodologies and outcomes will be delivered.A series of experimental 3D prototypes and artefacts will be created and used to generate new exhibition proposals. An exhibition of portraits/self-portraits at an internationally recognised gallery.

研究背景本次调查将使用三名女性受试者来研究艺术家如何创造性地参与3D扫描，3D软件应用和3D快速打印的进步，以实现3D肖像/自画像。它将考虑当代身体扫描工具是否可以方便地捕捉自然的姿势或动态的姿势，以揭示每个女性角色的情绪状态。我在哈德斯菲尔德、伦敦和格拉斯哥进行的试点身体扫描表明，身体扫描有可能揭示内在和外在的自我。然而，目前的身体扫描系统被设计为提取准确的身体测量，这意味着扫描亭和他们使用的软件有一个非常狭窄的焦点。为了保证“良好”的数据，拍摄对象必须一动不动地站着，采取预定的姿势。这是因为许多人为因素会对扫描过程和数据收集产生不利影响。这些问题包括皮肤的透明度，头发，阴影和不必要的运动。调查将使用Wicks和Wilson的TriForm BodyShape扫描仪在三维空间中捕捉女性受试者。这种白光技术是安全的，在我进行的初步测试中，它提供了最准确的数据。每位女性受试者都将测试这项技术，作为捕捉情绪和手势的系统。每次扫描将创建一个包含150万个坐标点（云数据）的三维地图，准备在3D软件包中使用。为了充分发挥每个人像的潜力，我会认真研究云数据人像。传统上，这些数据被查看、分析和清理，以删除任何不需要的信息，但我热衷于用艺术知识和直觉来增强肖像。在试图揭示女性身份的内在和外在方面时，我的目标是在Unver博士的帮助下转换捕获的数据，Unver博士是哈德斯菲尔德大学创意技术系的3D扫描和软件专家。这种操作有多种形式：不必要的动作可以通过数字雕刻来显示手势；一个特定的立场或姿势可能会被夸大，以创造一个新的戏剧性的强调；可以加入额外的3D线框道具来扩展肖像的视觉叙事并暗示情感状态。通过这个过程，我的目的是研究与肖像和自画像雕塑相关的自由和表达技术是否可以在3D软件环境中进行数字化开发。雕刻数据与雕刻物理材料有何不同？传统的触觉是通过鼠标的移动来记录的，这种亲密的过程能进化出来吗？数字3D环境有什么可能取代传统的雕刻方法？将使用新的快速成型技术构建一系列修改后的肖像/自画像。该过程的一个重要目标是发现不同的快速原型程序和材料将如何影响3D肖像/自画像的生产和建设。这个调查是过程驱动的，并将随着时间的推移而发展。顾问和同行团体将在确定的点上为这一进程作出贡献。过程将重复，允许新的发现为未来的方法和工作实践提供信息，以应对不断扩大的知识库。潜在的应用和好处：方法将被记录下来，文档将通过网站/博客提供。撰写的文章将被发表在同行评议的期刊上。将提交一篇学术论文，介绍研究方法和成果。将创建一系列实验性的3D原型和人工制品，并用于生成新的展览方案。在国际知名画廊举办的肖像/自画像展览。
