Abstract
Abstract. HBIM technology makes great contributions to 3D digital preservation and management of the existing traditional architectures, and VR technology has also been gradually emphasized by 3D users in recent years, especially 3D immersive situation makes users more likely to experience the real space field. Taking Han type traditional architecture with relatively complex geometrical structure as an example, this research carries out digital preservation through HBIM technology and tries to switch to VR platform to allow users to enter 3D immersive scene for management and display. It is shown in the research results that the application of integration of HBIM and VR technology to Han type traditional architecture needs to consider 3D digital model of the architecture, and the number of polygon shall be controlled below about 2 million, which can make the operation in VR environment more smooth; the integration of two technologies can achieve the purpose of 3D immersive digital management, which can provide the humanized application close to the real experience for the display of subsequent management of ancient relics and architectural aesthetics.
Highlights
Building information model (BIM) has been considered to be an important tool for architecture design, construction engineering and other related fields, which can produce critical and revolutionary change to the integration of industry; HBIM has the same effect on the preservation and maintenance of historical architecture, and has made great contributions [1], [2]
HBIM is applied to existing construction plan, it conforms to the digital management and applications of traditional architecture, architecture 3D digital is different from the scene of game software, which has the specifications for the precision of space size, and accurate and complete recording of the existing architecture size, appearance and size is the demand necessary for the subsequent application
Autodesk Revit platform is one of software widely used for establishment of HBIM, general VR platform tries to provide the functions compatible to Autodesk Revit to ensure the application of BIM in VR, such as the Unity [9] and COVISE [5], the transposition of Autodesk Revit to Unity must be through the assistance of 3DMAX
Summary
Building information model (BIM) has been considered to be an important tool for architecture design, construction engineering and other related fields, which can produce critical and revolutionary change to the integration of industry; HBIM has the same effect on the preservation and maintenance of historical architecture, and has made great contributions [1], [2]. The research and development of VR wearable hardware allows users to place themselves in 3D digital scene and make interactive experience with virtual digital contents [4] Such development makes BIM users research and integrate the feasibility of BIM and VR, and specific interface information is provided to the conversion between the data format of BIM and the data format of VR, so important achievements are obtained [5]. HBIM is applied to existing construction plan, it conforms to the digital management and applications of traditional architecture, architecture 3D digital is different from the scene of game software, which has the specifications for the precision of space size, and accurate and complete recording of the existing architecture size, appearance and size is the demand necessary for the subsequent application. Users will be placed and close to real 3D space scene for more effective digital management; observe architectural form and structure from different angles and experience the essence of traditional architecture process; Internet provides more convenient way to experience to global interested users
