Nevertheless, the observation of direct outcomes of this theory on mundane objects is impossible because they can only be witnessed when travelling at relative speeds approaching the velocity of light c. These effects are so counterintuitive and contradicting with our daily understanding of space and time that physics students find it hard to learn relativity beyond mathematical equations and to understand the deep implications of the theory. Advances in Computer Graphics and Interaction Technology now make it possible to actually experiment the effects of relativity in a 3D immersive environment. We propose a Virtual Reality framework to study and learn relativity as well as to develop some intuition of the relativistic effects and the quadri-dimensional reality of space-time. More precisely, an innovative rendering engine and a non-Newtonian physics engine are combined to compute relativistic effects. Experiments are proposed within a game-oriented carom billiard environment. Our work improves over previous efforts in the ability i) to render in real-time multiple relativistic objects, each moving with a different velocity vector ii) to enable interactions between objects and iii) to enable the user to interact with the objects and modify the scene dynamically. The originality of our 4D rendering engine lies in its capacity to efficiently store and retrieve non-simultaneous past space-time events that are visible by an observer at a specific location and at a given instant of his proper time.","PeriodicalId":346701,"journal":{"name":"2011 IEEE Virtual Reality Conference","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127878584","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}

Simulator X is targeted at Virtual Reality, Augmented Reality, Mixed Reality, and computer games. It provides a foundation and testbed for a variety of different application models. The current research architecture is based on the actor model to support fine grained concurrency and parallelism. Its design follows the minimize coupling and maximize cohesion software engineering principle. A distributed world state and execution scheme is combined with an object-centered world view based on an entity model. Entities conceptually aggregate properties internally represented by state variables. An asynchronous event mechanism allows intra- and interprocess communication between the simulation actors. An extensible world interface uses an ontology-based semantic annotation layer to provide a coherent world view of the resulting distributed world state and execution scheme to application developers. The world interface greatly simplifies configurability and the semantic layer provides a solid foundation for the integration of different Artificial Intelligence components. The current architecture is implemented in Scala using the Java virtual machine. This choice additionally fosters low-level scalability, portability, and reusability.","PeriodicalId":346701,"journal":{"name":"2011 IEEE Virtual Reality Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129036728","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, a new family of techniques for creating rectangular boxes of arbitrary position, orientation, and size is presented and evaluated. These new techniques are based solely on position data, making them different from typical, existing box shaping techniques. The basis of the proposed techniques is a new algorithm for constructing a full box from just three of its corners. The evaluation of the new techniques compares their precision and completion times in a 9 degree-of-freedom (DoF) docking experiment against an existing technique, which requires the user to perform the rotation and scaling of the box explicitly. The precision of the users' box construction is evaluated by a novel error metric measuring the difference between two boxes. The results of the experiment strongly indicate that for precision docking of 9 DoF boxes, some of the proposed techniques are significantly better than ones with explicit rotation and scaling. Another interesting result is that the number of DoF simultaneously controlled by the user significantly influences the precision of the docking.","PeriodicalId":346701,"journal":{"name":"2011 IEEE Virtual Reality Conference","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115760923","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}
