Real-time interactive systems such as virtual environments have high performance requirements, and profiling is a key part of the optimisation process to meet them. Traditional techniques based on metadata and static analysis have difficulty following causality in asynchronous systems. In this paper we explore a new technique for such systems. Timestamped samples of the system state are recorded at instrumentation points at runtime. These are assembled into a graph, and edges between dependent samples recovered. This approach minimises the invasiveness of the instrumentation, while retaining high accuracy. We describe how our instrumentation can be implemented natively in common environments, how its output can be processed into a graph describing causality, and how heterogeneous data sources can be incorporated into this to maximise the scope of the profiling. Across three case studies, we demonstrate the efficacy of this approach, and how it supports a variety of metrics for comprehensively bench-marking distributed virtual environments.

“…Previously [Zeleznik et al 2000] and more recently [Berthelot et al 2011] used a scene graph as a data structure to intermediate between various 3D applications. Similarly, we rely on a scene graph as a file-format-independent representation that can easily be manipulated and stored in a DB.…”

(a) 3D RCViewer (b) 3D Web ClientFigure 1: We define a novel 3D Repository that supports version tracking and asset distribution built on top of a NoSQL database. In (a), the 3D Revision Control Viewer enables repository inspection, individual revisions retrieval as well as conflict resolution and merging. In addition, the 3D Web Client, (b), remotely visualizes the contents of the repository in a web browser. Model courtesy of Network Rail. AbstractThe maintenance of assets in a large 3D scene can involve many authors with potentially different skills and different modeling tools. The standard paradigm of collaborative editing is sharing of files between various instances of applications. This presents problems, not limited to maintaining consistency of the models and dealing with concurrent edits in the same part of a scene. In this paper, we present a novel framework for non-linear revision control and online distribution of 3D assets. This framework supports concurrent asynchronous 3D editing of models and tracking of multiple revisions so that they can be integrated at a later date. It thus provides similar functionality to file-based revision control systems, but is built around a NoSQL database, hence avoids the constraints of file based storage. The framework supports distributed editing over the Internet and additional lightweight clients in web-browsers with WebGL support.

In today's globalized markets, effectivity in the way that product development information is communicated and transparently interpreted by a diversity of divisions and disciplines in an enterprise has an essential impact on the key factors time, cost and quality. Against the background of current activities in the automotive industry, we have conducted a process chain analysis at multiple OEMs and suppliers, analyzing application potentials of JT as the format of origin specifically for CAx processes, such as Digital Mock-Up, Simulation and Downstream production. In this context, a simple application to investigate and manipulate JT data in terms of structure and properties would provide the means for prototypical integration tests. Connecting containers available in the JT Open Toolkit to those provided in the OpenSceneGraph (OSG) graphics toolkit, the fundamentals of such an application were developed and are presented in this paper.
