Three-dimensional modeling of virtual hoisting machinery is the critical works to structure the system of virtual construction,and the foundation to realize intelligent and interactive virtual hoisting. 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.
