Abstract: This article introduces a method for constructing a BIM visualization platform based on a cloud-native environment and explains its key technologies and application directions. Under the application of innovative cloud rendering techniques, it solves several pain points in the traditional BIM visualization process and achieves efficient, high-quality, and elegant rendering of BIM models. The platform aims to provide BIM services as Software as a Service (SaaS) and, in the process of construction and exploration, addresses many technical challenges e.g., multi-source and heterogeneous model conversion, optimization of rendering large models, and high concurrency. It has developed a mature and usable method for constructing a BIM cloud rendering platform. Additionally, on the application and promotion of the platform, taking into account the characteristics of the construction industry, it has conducted a series of explorations in BIM collaboration scenarios, which objectively analyzes and forecasts the development prospects of cloud rendering in BIM visualization considering the current technological conditions.
