Abstract

BIM MEP models are the data support for visualising building information in "smart cities". To address the key visualization issues such as inefficient data scheduling of BIM MEP models, this paper proposes a data organization method for BIM MEP models that combines instantiation technology. The method firstly generates instance groupings based on the instance information of the electromechanical model components, secondly spatially divides and hierarchically clusters the massive component models by using KD trees according to the spatial distribution characteristics of the BIM electromechanical models, and finally combines with instantiation techniques to batch render the BIM electromechanical models. The experimental results show that the framerate of the optimised BIM MEP model is about 50 fps, and the lowest framerate is stable at about 30 fps, which can better ensure the visualization effects of the massive MEP model.
