Super-Large Building Oriented BIM Lightweight Method

With the development of building information technology, building information modeling (BIM) plays an increasingly important role in the construction industry. Aiming at the handling of large amount of original data, data exchange difficulty, and low efficient rendering for super-large buildings, the data conversion method, geometric data compression algorithm and high-performance transmission and rendering engine for heterogeneous models are studied, and an integrated transmission and rendering engine is designed.
