An image-based virtual environment is generally represented as an extensive field, in scenes showing mainly a landscape, and most objects are beyond the viewer's reach. Additionally, it usually has a single suitable point for observation because of limitations in the capture and representation methods of 3D-image spaces. Therefore, a special technique has to be developed that enables interaction with the environment. This paper describes the concept of a technique to interact with the scene based on a telescope-like virtual tool. The tool enables the user to stereoscopically view a distant object that will appear to be within reach, and to manipulate the object directly by putting a hand in the \"scope\". Hence, the user can handle objects at any distance, seamlessly and from the best viewpoint, without leaving an immersive environment.","PeriodicalId":210571,"journal":{"name":"International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126218734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was implemented by using the Java language and the Java 3D class library to enhance its portability. It3d makes it easy to construct AR applications that are portable and adaptable. It3d consists of three sub-libraries: an input/output library for distributed devices, a 3D widget library for multimodal interfacing, and an interaction-recognition library. The input/output library for distributed devices has a uniform programming interface style for various types of devices. The interfaces are defined by using OMG IDL. The library utilizes multicast peer-to-peer communication to enable efficient device discovery and exchange of events and data. Multicast-capable CORBA functions have been developed and used. The 3D widget library for the multimodal interface has useful 3D widgets that support efficient and flexible customization based on prototype-based object orientation, or a delegation model. The attributes of a widget are used to customize it dynamically. The attributes constitute a hierarchical structure. The interaction-recognition library is used to recognize basic motions in a 3D space, such as pointing, selecting, pinching, grasping, and moving. The library is flexible, and the recognition conditions can be given as parameters. A new recognition engine can be developed by using a new circular event history buffer to efficiently manage and retrieve past events. Development of immersive AR applications using it3d demonstrated that less time is needed to develop the applications with it3d than without it. It3d makes it easy to construct AR applications that are portable and adaptable.","PeriodicalId":210571,"journal":{"name":"International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123947682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These renderings, due to their high-quality image synthesis, can take minutes to hours to render. Nowadays, as the computing power has increased dramatically, the size and complexity of the datasets generated by the super-computer can be overwhelming. It is almost impossible for the visualization techniques to achieve interactive frame rates. Our work focuses on using Image-Based Rendering (IBR) techniques to manage and explore large and complex datasets and virtual scenes on a remote display across the world-wide-web. The key idea for this research is to pre-process the datasets and render key viewpoints on pre-selected paths inside the dataset. We present new techniques to reconstruct approximations to any view along the path, which allows the user to roam around inside the datasets with interactive frame rates. We have implemented the pipeline for generating the sampled key viewpoints and reconstructing panoramic-based IBR models. Our implementation includes an efficient two-phase caching and pre-fetching scheme. The system has been successfully tested on several datasets and satisfying results have been obtained. Analysis of errors is also presented.","PeriodicalId":210571,"journal":{"name":"International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126980550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the benefits of user-object interactions are best realized in interactive environments which require the rapid computation of deformations. In this paper we present a prototype of a system for the simulation of elastic objects in Virtual Environments (VE) under real-time conditions. The approach makes use of the method of finite elements and precomputed Green's functions. The simulation is interactively visualized in fully immersive rear-projection based Virtual Environments such as the CyberStage and semi-immersive ones such as the Responsive Workbench. Using pick-ray interaction techniques the user can interactively apply forces to the object causing its deformation. Our interactive visualization module, embedded in VE system Avango, supports real time deformations of high-resolution 3D model (10,000 nodes) at a speed >20 stereoimages/sec.","PeriodicalId":210571,"journal":{"name":"International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129901589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
