Realistic Computer Simulation For Construction Process Of Structures

According to the research for realistic simulation of construction process, this work designs and implements a realistic simulation system of construction process. The system has a highly realistic virtual environment, which can simulate the construction process realistically and dynamically. The system enables users to create 3D model of construction machinery and can be integrated into the demonstration animation of construction plan. It also allows users to walk through the virtual environment during the construction process, and inquire about real-time information, such as relative position, displacement, internal force changes and elastic deformation of components in every phase of construction process. It can be used as a dynamic realistic visualization tool to facilitate us to analyze the construction process. This paper has mainly done the following research:(1) Establish a highly realistic virtual construction environment, which allows users to add customized three-dimensional model. Collision detection of the virtual object enhances the sense of immersion of the environment, allowing users to walk through the virtual scene following an arbitrary path.(2) Establish more realistic three-dimensional models of construction machines, and simulate their behavior, so that the simulation of construction process will be more realistic.(3) Provide 3D3S (a common structural analysis software) data interface, on the basis of which we develop the animation data format. The data of key frame of animation is saved as that new format, for the purpose of playback of the animation.(4) Take a new mechanism to implement the key frame animation of construction process. In order to solve the problem of insufficient memory when load files in one time, we load the key-frame files in batches. Propose the method to integrate machinery animation into the animation of the structure.
