Abstract

The present invention provides a BIM-based mobile terminal architectural model rendering performance optimization method and system, including: performing lightweight processing on the first BIM model to obtain a third BIM model; Visible widgets are rendered. The lightweight steps include: exporting the first BIM model to the second BIM model, and saving the component color and material information of the components in the first BIM model; simplifying the solid mesh of the second BIM model, and processing the boundary representation, to obtain the second BIM model Three BIM models. The invention solves the difficulty that the mobile terminal cannot render the BIM model due to insufficient hardware performance, and can render the BIM model on the mobile terminal smoothly and without lag.

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 ...
