It consists of a toolkit for Augmented Reality, named RPR- SORS, which is composed of two artifacts: an API that handles various computer graphics techniques in a novel pipeline approaching illumination, reflectance model, shadowing, composition, and camera effects; and a material editor that accelerates the creation of complex photorealistic materials. An experimental application was developed with the proposed solution, where both the API and material editor were used to accomplish photorealistic effects in an application of Augmented Reality in architecture. The results obtained show that the API provides a flexible infrastructure for the photorealistic Augmented Reality pipeline, and that the material editor facilitates the creation of photorealistic materials and their use for Augmented Reality","PeriodicalId":287558,"journal":{"name":"2011 XIII Symposium on Virtual Reality","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114520559","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}

Boulanger","doi":"10.1109/SVR.2011.35","DOIUrl":"https://doi.org/10.1109/SVR.2011.35","url":null,"abstract":"Optical motion capture is a prevalent technique for capturing and analyzing movement. However, a common problem in optical motion capture is the missing marker problem due to occlusions or ambiguities. Most methods for resolving this problem either require extensive post-processing efforts or become ineffective when a significant portion of markers are missing for extended periods of time. In this paper, we present an approach to reconstruct human motion corrupted in the presence of missing or mis-tracking markers. We propose a data-driven, piecewise linear predicting kalman filter framework to estimate missing marker position, and reconstruct human motion in real time by rigid body tracking solver. It allows us to accurately and effectively reconstruct human motion within a simple extrapolation framework. We demonstrate the effectiveness of our method on real motion data captured using OptiTrack. Our experimental results demonstrate that our method is efficient in recovering human motion.","PeriodicalId":287558,"journal":{"name":"2011 XIII Symposium on Virtual Reality","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126225763","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 is due to the ever increasing demand for oil derivates in the international market. The extraction of this mineral, however, is not an easy process. It poses many hazards which may threaten the environment and the lives of workers at an oil well. In order to reduce the chances of accidents and failures, a continued training to the workers is highly recommended. This paper presents a game which simulates a drilling rig. This game, the players are exposed to various circumstances  in which they can exercise their knowledge about their work and learn what to do in troublesome events. Artificial Intelligence techniques will be applied to the game in order to accomplish that feature. The application will also include instant interactions among several players in a virtual 3D environment.  The game is a web-based, which allows players to remotely execute it on different platforms.","PeriodicalId":287558,"journal":{"name":"2011 XIII Symposium on Virtual Reality","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124534450","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}

Many models to simulate crowds have been developed over the years and can be classified into two big groups (macroscopic and microscopic) according to how the agents are managed. In some macroscopic models the agents are grouped and guided by the potential field of their group. The construction of potential fields is the bottleneck of those models, so it is necessary to use a small number of groups in order for a simulation to run at interactive frame rates. In this article, it is proposed a model based on a macroscopic model, which, mainly, aims at reducing the cost of computing the potential fields of the groups, by using groups discretized according to the needs of the environment. At the same time, it is proposed the addition of groups that can steer the agents of a simulation to momentary goals, which gives the crowd a wider variety of behaviors. Finally, it is proposed the use of a social forces model to prevent collisions between agents and between agents and obstacles.","PeriodicalId":287558,"journal":{"name":"2011 XIII Symposium on Virtual Reality","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124033758","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}
