With the multiplication of sensors in these systems, new constraints emerged, especially how to preserve the 3D interaction continuity. An approach for answering this is to process the huge amount of incoming data and how to estimate a correct interpretation from it. However data processing is often a complex approach. In this paper, we present to you a framework that can be used such an upper-layer on the hardware layer to provide data processing and data fusion to a virtual reality application and so provide an adaptative behaviour to the system.","PeriodicalId":182702,"journal":{"name":"Proceedings of The 7th ACM SIGGRAPH International Conference on Virtual-Reality Continuum and Its Applications in Industry","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127566679","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}

According to their architecture and Direct3D9 application execution flow on single node, we present transparent shader-based Direct3D9 application parallelization strategy. We has divided graphics cluster into two types of logical node, i.e. resource distributing node (D-Node) and resource rendering node (R-Node). Among them, D-Node is responsible for converting Direct3D9 application to six kinds of rendering resource, including command stream, vertex shader, pixel shader, vertex stream, index stream and texture stream, R-Node is responsible for reconstructing Direct3D9 interface rendering command based on the description information and resource data of received rendering resource. Each R-Node distributes rendering task by computing the bounding box of multi-stream based scene data in the screen space. Experimental results have shown that this strategy can realize transparent shader-based Direct3D9 application parallelization and support high-resolution tiled display. In contrast to single node rendering, four nodes parallel rendering based on graphics cluster can not only promote rendering performance but also achieve average speedup at 2.9.","PeriodicalId":182702,"journal":{"name":"Proceedings of The 7th ACM SIGGRAPH International Conference on Virtual-Reality Continuum and Its Applications in Industry","volume":"641 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121985365","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}

The 3D avatar is reconstructed from multi-view images of the player with image-based modeling and rendering techniques. The 3D avatar can be dynamically reconstructed and rendered in real time by using the Hardware-accelerated Visual Hull(HAVH) method. The visual appearances and physical activities of the player are projected onto the avatar. The player can see themselves in the virtual 3D space and interact with the virtual objects through the bodily movements of the avatar in the gaming world.

Instead of using the whole hologram plate resolution or carrying out point-wise judgment, this approach pre-divides the object space into subspaces and calculates an effective hologram plate region for each subspace according to interference fringe spatial frequency and grating diffraction energy distribution. As both the very low and very high spatial frequency portions are filtered out, the quality of the reconstructed image is even better in terms of sharpness. This space subdivision based approach also makes parallel CGH computing more straightforward. A simple load-balancing strategy is given.","PeriodicalId":182702,"journal":{"name":"Proceedings of The 7th ACM SIGGRAPH International Conference on Virtual-Reality Continuum and Its Applications in Industry","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131105106","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}

This paper provides a practical approach to do occlusion registration which is a key cue for users to understand the scene. We apply our method to Video-based Augmented Reality where detecting occlusion relationship is challenging because virtual objects are simply superimposed on images of real scenes. By estimating the dense depth of real objects from stereo, results show our approach can efficiently and correctly register virtual and real objects.","PeriodicalId":182702,"journal":{"name":"Proceedings of The 7th ACM SIGGRAPH International Conference on Virtual-Reality Continuum and Its Applications in Industry","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125660758","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 this paper we present new haptic guides for object selection. It is utilized to augment the Follow-Me 3D interaction technique dedicated to object selection and manipulation. We divide the VE into three different zones (free manipulation, visual and haptic assistance zones). Each one of the three zones is characterized by a specific interaction granularity which defines the properties of the interaction in the concerned zone. This splitting of VE is aimed to have both precision and assistance (zones of visual and haptic guidance) near the object to reach or to manipulate and to maintain a realistic and free interaction in the VE (free manipulation zone). The haptic and visual guides assist the user in object selection. The paper presents two different models of the haptic guides, one for free and multidirectional selection and the second for precise and single direction selection. The evaluation and comparison of these haptic guides are given and their effect on the user's performance in object selection in VE is investigated.","PeriodicalId":182702,"journal":{"name":"Proceedings of The 7th ACM SIGGRAPH International Conference on Virtual-Reality Continuum and Its Applications in Industry","volume":"24 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123049762","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}
