Collaborative Visualization of a Warfare Simulation Using a Commercial Game Engine

The requirement about reusable 3D visualization tool was continuously raised in various industries. Especially in the defense modeling and simulation field, there are abundant researches about reusable and interoperable visualization system, since it has a critical role to the efficient decision making by offering diverse validation and analyzing process. Also to facilitate the effectiveness, many current operating systems are applying VRVirtual Reality and ARAugmented Reality technologies aggressively. In this background, we conducted the research about the design for the collaborative visualization environment for the warfare simulation through commercial game engine. We define the requirements by analyzing advantages and disadvantages of existing tools or engines like SIMDIS or Vega, and propose the methods how to utilize the functionalities of commercial game engine to satisfy the requirements. The implemented prototype offers collaborative visualization environment inside the CAVE environment, which is the facility for immersive virtual environment, by cooperating with handheld devices.

Development of v-DMU Based on e-Science Using COVISE and SAGE

Virtual digital mock-up (v-DMU) refers to all of the activities in the design, analysis, and visualization of the product in a 3D virtual environment that lead to a lower cost and a higher quality. In the early days, designers exchanged CAD files directly in collaborations. Recently, DMU systems have been used for relatively effective designs that generally support distributed and collaborative design capability by sharing the design data via the Internet. However, a range of problems can arise in such a case. In the case of large-scale products such as aircrafts or ships, the data size can be on a scale so large that it requires large amount of space on the workstation and requires considerable time for exchanges. Moreover, security problems often occur in the process of data exchanges. For a company and a nation, this can be crucial. The immersive visualization of product design data is becoming more important in collaborative design. As a solution to these issues, this paper proposes a new approach using the technology of the remote visualization of CAD data. This involves the streaming of rendered graphics using COVISE and SAGE. This paper also introduces the implementation of v-DMU based on e-Science by remote visualization.

The Virtual Factory Layout Simulation System using Legacy Data within Mixed Reality Environment

ABSTRACT Digital virtual manufacturing is a technology that aims for the rapid development of products and the verification of production-process in ways that are more efficient by integrating digital models within the entire manufacturing process. These digital models utilize various information technologies, such as 3D CAD and simulations. Mixed reality, which represents graphical objects for only needed parts against real scene, can bring a more enriched sense of reality to an existing virtual manufacturing system that is in a pure virtual environment, and it can reduce the time and money needed for modeling the environment. This paper suggests a method for planning virtual factory layouts based on mixed reality using legacy datathat are already constructed in the real field. To do this, we developed the method to acquire simulation data from legacy data and process this acquired data for visualization based on mixed reality. And then we construct display system based on mixed reality, which can simulate virtual factory layout with processed data. Developed system can reduce errors related with factory layout by verifying the location and application of equipments in advance before arrangement of real ones at the practical job site.Keywords:Legacy Data-Processing, Mixed Reality, Digital Virtual Manufacturing, Virtual Manufacturing Simulation, Safety Sign Panel
