Large Scale 3D Terrain Generation is a hot and difficult problem in many applications, such as Geographic Information System (GIS), Virtual Reality (VR) and 3D games. The key issues of 3D terrain Generation are how to store massive terrain data and how to simplify terrain model. For the storage and management of massive terrain data, an organization approach based on terrain partition and tile pyramid...
The image data transferred by embedded network devices directly lacks of extensibility. As different devices have different image formats, so the receivers may have difficulty in interpretation. This article proposes a method based on XML to solve this problem, researches coding and recoding of image and achieve image transferring by integrating the data into XML, finally validates the feasibility...
The scene simulation is an important part of virtual reality system. The creation and development of scene simulation provides powerful methods support to the research of forensic science. In this paper, the visual simulation and forensic science was closely integrated; the composition structure and function of OpenGL performer which is advanced development tools on the field of visual simulation...
