Abstract

The invention provides a BIM (Building Information Modeling)-based mobile terminal building model rendering performance optimization method and system. The optimization method comprises the following steps: performing lightweight processing on a first BIM to obtain a third BIM; only rendering members visible in the scene camera perspective in the third BIM. The lightweight processing step comprises the following sub-steps: deriving a second BIM from the first BIM, and storing the color material information of members in the first BIM; simplifying a solid mesh of the second BIM, and processing the boundary representation to obtain the third BIM. According to the invention, the problem that the BIM cannot be rendered due to poor mobile terminal hardware performance is solved; the BIM can be rendered on the mobile terminal smoothly.

Description

technical field [0001] The present invention relates to BIM application technology and IT fields, and more specifically relates to a technical method and system for optimizing rendering of BIM models on a mobile client. Background technique [0002] BIM is Building Information Modeling (Building Information Modeling), which is an innovative method of architectural design, construction and management. BIM breaks through the traditional design method. It is no longer a complicated two-dimensional drawing on the plane. The BIM model uses three-dimensional components to fully visualize the building, increasing intuitiveness and work efficiency. At present, the commonly used BIM modeling software is Autodesk's Revit. However, Revit has very high requirements for hardware equipment. It has very high requirements for the computer's CPU processing capability, GPU display capability, and memory graphics card, which increases the cost of equipment in disguise. [0003] 3D models on ...
