Aimed at enhancing the requests of image quality and stability of the virtual construction scene, taking a tower crane for example. We studied the technology of three-dimensional modeling and optimization of a virtual tower crane, and a method named two-stage model optimization was put forward. This depended on the modeling stage using Solidworks and 3DS Max and the performance optimization stage in EON. The practice of software development indicates that the proposed methods of three-dimensional modeling and optimization could satisfy the performance request of virtual construction system and be popularized to other virtual system.展开更多

As a hydropower project for an example, the terrain model using AutoCAD and 3DS Max combination of building, equipment model in 3DS max using entity model building. In the transporting section, will be built in 3DS max key frame together with the model of import in the EON and set the parameters of the animation node; In digging scene, using multiple place nodes to control of the excavator digging operation ; Interaction part of the scene, using the built-in mouse node （Click Sensor） and keyboard nodes （Keyboard Sensor） implementation scenarios and user interaction. Research shows that through excellent virtual reality software EON to apply virtual reality technology in earthwork construction simulation stage, found possible quality problems and potential safety problems in engineering, through the simulation can be more perfect earthwork construction. Verified, earthwork construction of virtual real earthworks has certain guidance and reference value.展开更多
