Key words virtual reality e-commerce network
1 Introduction
Virtual Reality (Virtual Reality) through multimedia technology and simulation technology combined to generate realistic visual, listening, tactile integration of the virtual environment, the user in a natural way to experience and interact with the objects in the virtual environment. However, most of the current e-commerce is based on the Web, real interactive virtual force feedback in which the popularity of a visual helmet and digital gloves and other equipment now 0 is extremely difficult (technical reasons,hogan scarpe, financial reasons). But the conventional input-output devices to the keyboard, mouse and monitor network constitute an interactive environment in the client browser virtual reality technology matures and perfect, Web 3D technology network the same virtual reality technology to simulate natural to experience realistic and interactive strong as the goal, to a considerable extent, efficient economy to achieve the goal of virtual reality systems.
Network virtual reality technologies emerge, not only promote the universal application of virtual reality technology, but also to e-commerce has brought a new application space to improve the quality of e-commerce. Fully understand the importance of virtual reality technology in e-commerce, to study the characteristics of the network virtual reality technology and its application of the law,Abercrombie Pas Cher, so as to further promote the development of e-commerce, e-commerce has become an important topic. The
2 virtual reality in e-commerce
2.1 characteristics of virtual reality technology.
Telepresence: users feel immersed in the virtual environment rendered in the browser.
More aware: The user perception of information in various forms such as vision, hearing.
Interactively: the user can close to the natural habit, with conventional input output devices on the object or scene in the virtual environment action and get feedback.
Authenticity: the movement of objects in the virtual environment close to comply with the laws of physics.
High efficiency: the creation and display of three-dimensional space in the virtual environment, not overly dependent on the client's hardware performance and real-time rendering, the small amount of data transfer required and can be streamed. The virtual reality
2.2's role in e-commerce. Due to the above characteristics of the network virtual reality technology, it is in the e-commerce playing a unique role:
realistic strong: narrowing the differences between online shopping and real shopping environment, is a virtual smart shopping mall close to the reality of the scene.
Stimulate buying enthusiasm: Online Products aims not only to showcase products, but more importantly, by allowing customers to learn more about the products and increase the purchase rate. Virtual network virtual reality technology can be generated by the user in the buying process assumptions, presented the results or effects. This will help to stimulate the enthusiasm of the user's purchase.
Expand the connotation of e-commerce: the INTERNET as commercial traffic channel is widely accepted, network virtual reality technology connotation is greatly broaden and extend the application of e-commerce. Virtual reality
3 network technology
network virtual reality technologies are mostly based on Web 3D [1] [2] [3] technology, Web 3D technology by the real-time 3D modeling and dynamic display of two parts. Real-time 3D modeling and dynamic display typically divided into two types, one is based on the geometric model, another is based on the image. Both technical solutions have their own characteristics, the former can easily create 3D space at any angle of observation, but computationally intensive, and thus higher hardware requirements modeling process is more difficult for complex models; latter uses image mosaic way to achieve real-time modeling, development of low cost, small amount of calculation and the results are realistic, but the large amount of data.
Network virtual reality technology in order to continue the development of this particular network environment, not only has the distinctive technical features, but also try to avoid weaknesses, to form the respective technical style, this is for our e-commerce The selection of the most appropriate network virtual reality technology has laid a good foundation for different display contents. In view of this, it is very necessary to research and comparative analysis of all major network virtual reality technology.
3.1VRML (Virtual Reality Modeling Language - Virtual Reality Modeling Language) [4] is dedicated to established online virtual reality design language, which uses geometric model-based real-time modeling and dynamic display methods. The VRML scene model can be used to establish the real world, and create fictional three-dimensional space. VRML provides a so-called 6 +1 degree view, i.e. the scene and rotation scene is moved along the three axial directions, but also can create a hyperlink with other 3D space.
VRML file is a text file, it can generate a text editor to write the file extension name. Wrl. Due to the more complex and strict the VRML language syntax rules greatly rely on manual writing VRML files workload establish some 3D modeling tools (such as 3DS MAX) visualization VRML files and automatically generate 3D space to improve the efficiency of the development but the VRML file data generated so than manual written documents is much larger.
VRML applied to construct a virtual three-dimensional environment, while somewhat inadequate to express the reality of the real world scenes and objects.
3.2QuickTime VR. QuickTime is Apple developed digital image film and television technical specifications, which contains a variety of media data compression / decompression technology. QuickTime VR is one of a new media data format. It contains the object Television (Object Movie), several forms the panoramic Television the (Panoramic Movie) and multi-node image (Multi-Node Scene), the file extension is the. Mov.
Past QuickTime Mac series on digital video specification, thus making QuickTime VR development tools are mostly run on a Mac, the lack of development tools on the PC, Windows, and now has appeared on many Windows QuickTime VR professional development tools, such as VR ToolBox, making the QuickTime VR film developed for e-commerce more convenient and efficient.
3.3Cult3D the Cycore network based on Java development,gucci borse, virtual reality technology, it has a unique way of rendering dynamic display extremely high quality image and does not rely on a 3D accelerator card and other hardware, the generated files (. Co) data a small amount may retain texture modeling tool created and can design a variety of interactive 3D objects and add sound, particularly suitable for expression of 3D objects on the network.
Cult3D technology itself has no ability to create 3D models, which rely on specialized 3D modeling tool software to create 3D models and 3D models exported by the plug-in installed software. 3DS MAX and Maya 3D modeling software that supports this feature. Action and interaction of 3D objects designed in of Cult3D the interactive features designed software Cult3D Designer file output for network compression.
Cult3D technology weaknesses is not easy to express a 360 ° panoramic virtual environments. 3.4Viewpoint Viewpoint company's network of virtual reality technology, whose official name is the VET (Viewpoint Experience Technology), and the and its predecessor famous MetaStream technology. Viewpoint developed virtual reality file a small amount of data that can flow download, dynamic display good image quality and real-time interactive control to change the texture maps are widely used on the Internet to express 3D objects. Viewpoint technology can be automatically adjusted according to the network conditions and display the 3D object detail and playback frame rate, and therefore its ability to adapt to network bandwidth.
Usually developed Viewpoint virtual reality file is exported from 3DS MAX ASE file import ASE files in the core application Viewpoint Viewpoint Scene Builder and corresponding 3D scene elements (such as: Material, animation, interactive action edit and design, final output the Viewpoint data file that can be played in the browser (. mts mtx) and the scene defined information).
3.5Flash Macromedia's the vector animation technology development. Flash animation online streaming technology, can install the Flash Player browser-smooth playback of Flash animation. In Flash animation, not only in the development environment to draw vector objects,sac longchamp, and can also import external vector graphics files, bitmap image files, sound files in multiple formats can even edit video files. Flash now been widely used for development of network interactive vector animation, however, to use it can also be a network of virtual reality development.
