Abstract

BRLO-Tree (Block-R-Tree-Loose-Octree) is presented in this paper based on the R-Tree and Loose-Octree. The aim of the structure is to visualize the large scale and complex dynamic scenes in a 3D (three-dimensional) GIS (Geographic Information System). A new method of clustering rectangles to construct R-tree based on an improved K-means algorithm is put forward. Landform in 3D GIS is organized by R-Tree. The block is used as the basic rendering unit. The 3D objects of each block are respectively organized by a Loose-Octree. A series of techniques, based on this data structure, such as LOD (Level of Detail), relief impostors are integrated. The results of the tests show that BRLO-Tree cannot only support the large scale 3D GIS scene exhibition with wandering and fighting, but it can also efficiently manage the models in a dynamic scene. At the same time, a set of integrated techniques based on BRLO-Tree can make the rendering pictures more fluence and the rendering time vastly improved.

’ perspectives. The findings will not only benefit the Panorama DL, but also all end-user oriented digital presentations of Dunhuang heritage, such as interactive media presentations or 3D immersive exhibitions. The methods used in this study also provide a reference for future evaluations of digital platforms of cultural heritage in Dunhuang and beyond.The Dunhuang Mogao Cave Panorama DL is available on the Dunhuang Research Academy website http://en.dha.ac.cn/ . It includes 17 scenes: the surroundings of the academy, the exhibition center outside the Grottoes, and 14 caves

Further Development of Information Technology Transfer Concept for Adaptation and Exploitation of European Research Results in the Baltic Sea Region Countries

This paper describes further development of information technology transfer concept for adaptation and exploitation of European research results in the Baltic Sea Region (BSR) countries. Riga Technical University (RTU) and Vilnius University (VU) as the partners of BSR Interreg Programme project BONITA (Baltic Organisation and Network of Innovation Transfer Associations) participate in the research which aims to develop a generic innovation & technology transfer concept (ITTC) to improve the collaboration between academia and industry. Particular attention in the paper is paid to the successfully proven concept of small and specialized exhibitions (the so-called "showrooms") run by technology suppliers and technology transfer facilitators. The creation of the distributed multi-organisational showroom-network environment in the framework of BONITA project for the purpose of technology & innovation transfer improvement is described.
