Crafting Ceramics through the Use of Virtual Reality
FormAkademisk - forskningstidsskrift for design og designdidaktikk
This paper reflects ongoing research about how new technology creates new possibilities within crafting and how it can build on traditional techniques within the field of ceramics. The research explores how virtual reality (VR), using Oculus Rift and 3D-printing in clay is suitable to link to the process of throwing vessels within ceramic crafts. The quality of the crafted objects in question is based on the ability of the presented technique to combine throwing and pattern-making as an integrated process while building up the thrown object, here named virtual pattern-throwing. Furthermore, it is argued that this use of VR for throwing makes it possible to recall a hands-on experience and thus weave the quality of the traditional craftsmanship with the virtual within the process of making vessels.
Virtual Pottery: An Interactive Audio-Visual Installation
2012
Virtual Pottery is an interactive audiovisual piece that uses hand gesture to create 3D pottery objects and sound shape. Using the OptiTrack motion capture (Rigid Body) system at TransLab in UCSB, performers can take a glove with attached trackers, move the hand in x, y, and z axis and create their own sound pieces. Performers can also manipulate their pottery pieces in real time and change arrangement on the musical score interface in order to create a continuous musical composition. In this paper we address the relationship between body, sound and 3D shapes. We also describe the origin of Virtual Pottery, its design process, discuss its aesthetic value and musical sound synthesis system, and evaluate the overall experience.
Virtual pottery: a virtual 3D audiovisual interface using natural hand motions
Multimedia Tools and Applications, 2013
In this paper, we present our approach towards designing and implementing a virtual 3D sound sculpting interface that creates audiovisual results using hand motions in real time. In the interface "Virtual Pottery," we use the metaphor of pottery creation in order to adopt the natural hand motions to 3D spatial sculpting. Users can create their own pottery pieces by changing the position of their hands in real time, and also generate 3D sound sculptures based on pre-existing rules of music composition. The interface of Virtual Pottery can be categorized by shape design and camera sensing type. This paper describes how we developed the two versions of Virtual Pottery and implemented the technical aspects of the interfaces. Additionally, we investigate the ways of translating hand motions into musical sound. The accuracy of the detection of hand motions is crucial for translating natural hand motions into virtual reality. According to the results of preliminary evaluations, the accuracy of both motioncapture tracking system and portable depth sensing camera is as high as the actual data. We carried out user studies, which took into account information about the two exhibitions along with the various ages of users. Overall, Virtual Pottery serves as a bridge between the virtual environment and traditional art practices, with the consequence that it can lead to the cultivation of the deep potential of virtual musical instruments and future art education programs.
3DIVS: 3-dimensional immersive virtual sculpting
Proceedings of the …, 1999
Virtual Environments (VEs) have the potential to revolutionize traditional product design by enabling the transition from conventional CAD to fully digital product development. The presented prototype system targets closing the "'digitalgapJZ as introduced by the need for physical models such as clay models or mockups in the traditional product design and evaluation cycle. We describe a design environment that provides an intuitive human-machine interface for the creation and manipulation of three-dimensional (3D) models in a semi-immersive design space, focussing on ease of use and increased productivity for both designer and CAD engineers.
Journal on Computing and Cultural Heritage
Visualizing human motion is a topic that has gained increasing attention in the domain of cultural heritage, due to the need for capturing intangible dimensions, existing for example in theatrical performances, dances, and crafts. In this respect, virtual humans are typically employed to re-enact human motion, executing movements reproduced through predefined animations, or physics simulation engines. In the case of traditional crafts, a defining point is how to model the interaction of virtual humans with craft-related objects and how to transfer it from the physical to the digital world. Toward a more effective and generic modeling and visualization of the interaction of humans with tools and machines utilized in crafts, this article proposes a novel methodology for the modeling and visualization of crafts and presents a platform enabling the authoring and visualization of craft processes. We contribute a way of visualizing craft processes within virtual environments, aiming to in...
Rollouts of Fine Ware Pottery using High Resolution 3D Meshes
2010
A common part of the documentation of archaeological finds is the drawing of so-called rollouts. Rollouts provide a complete and continuous depiction of graphical elements on the surface of rotation-symmetric objects and are especially useful for the iconographic interpretation of figurative vase painting. In the past, rollouts were created either by manual drawing or photographically. We propose a new method to generate rollouts in which the tedious process of manual drawing or the disadvantage of having to decide on a specific projection in advance of any photographical process is replaced by the acquisition of a digital coloured surface model using a structured-light 3D scanner. This model is then used to generate high-quality rollouts with arbitrary projection parameters. To handle curved vessel profiles, we divide the vessel's surface into multiple segments. Each segment is then approximated with a frustum which serves as a developable auxiliary surface. In the rollout generation process, the vessel's surface is projected onto a frustum's mantle, which is then developed into the image plane. The shape of each frustum is selected in such a way that projection distortions are minimized, but interrelated graphical features like figural friezes are still unrolled in one piece. To control distortion effects in rollouts of non-developable surfaces, we investigated the use of cartographic methods. A first implementation of our method generates true-to-scale rollouts from meshes provided as PLY files and writes them to a raster image file. Our program uses off-screen OpenGL in combination with tiled rendering to generate high-resolution images which are suited for professional printing. Exemplary results from the Austrian Corpus Vasorum Antiquorum (CVA) project of the Kunsthistorisches Museum Wien (KHM - Museum of Art History in Vienna) and the Universalmuseum Joanneum Graz (UMJ) are shown.
A Shattered Perfection: Crafting a Virtual Sculpture
In the development of a digital sculpture for a competition entry, a mathematical approach was investigated as a method to develop a variety of forms. This paper covers the initial inspiration for the sculpture, Georg Nees's Gravel Stones, and then the series of approaches that were developed expanding the starting concept. Each step in the process is described including the decisions and alternatives that were explored. The sculpture was entirely built and developed with custom software using a series of related mathematical concepts. The software and related digital representations became the sculpting material and the sculpting tools.
VirSculpt: a virtual sculpting environment
2004
We describe a virtual sculpture environment suited to the needs of artists. In this approach, the user is immersed in a virtual environment by the use of haptic devices and immersive display. The project is focused around four main research topics: the sculpture model, the tools and their actions on the model, the display of the sculpture, and the interface between the artist and its virtual work. First results are presented and future works are discussed.
Integration of Complex 3D Models Into VR Environments – Case Studies from Archaeology
2021
Recently, virtual reality technologies are increasingly being introduced into our lives. The focus of their use is shifting from the entertainment industry to design, healthcare, tourism, architecture, education and more. The advantages of virtual reality technology are especially noticeable in the field of archaeology, as many historical objects have not survived to our time, and their appearance can be reproduced only on the basis of historical sources and archaeological excavations. Most platforms for implementing virtual reality programs are based on game engines that can provide the required level of performance for VR. Such platforms show very good results for architectural objects, which often have many similar elements of simple shapes. Integrating complex objects with unique shapes is usually a problem. In this article, we consider the use of photogrammetric methods to create 3D models of historical objects and the aspects of their integration into a virtual environment bas...
VISUALIZATION OF UNDONE: COMPUTER AIDED ARTISTIC AND INDUSTRIAL CERAMIC VISUALIZATION
Seres 2009 I.Uluslararası Seramik, Cam, Emaye Sır ve Boya Kongresi Bildiri Kitapçığı
Designing with computer has lots of advantages over the traditional designing techniques which had been made on paper. These advantages is the result of the medium we use; virtual reality (VR). Designing process starts on paper using morphological charts in order to fit design and function. After the design process, visualization process will occur which includes drawing of the virtual shape, applying the virtual material, setting correct light and rendering it on computer screen. This process gives designers the ability to focus on details and observe the object without shaping it. This kind of process could be used for designing ceramics.
