The invention discloses a method suitable for improving the physical material effect of a BIM
information model. The method comprises the following steps that S1, the BIM model is constructed; s2, attribute parameters such as model component sharing parameter ID are added; s3, exporting a BIM model Mesh
data file and a BIM attribute information report; s4, UV manufacturing is carried out; S5, PBR
texture mapping manufacturing is carried out; s6, exporting the detailed statement; s7, establishing a
database; s8, building a
background data service; s9, importing the PBR physical material model output in the step S4 into a three-dimensional engine, and performing three-dimensional scene effect adjustment in combination with engine characteristics; s10, reading a model component ID through program development, and interactively editing attribute information according to the model ID and
background data service; and S11, finally realizing the BIM model PBR physical material to improve the
simulation effect. According to the method, a BIM attribute information
background data service is built in combination with a
database, and the BIM with a PBR physical material effect is displayed through a three-dimensional
visualization engine, so that the PBR effect of the BIM is improved, and the attribute information integrity of the model is ensured.
