The invention discloses a
virtual reality scene modeling method and
system based on
big data, and relates to the technical field of
virtual reality, and the method comprises the steps: matching a model component
library, a texture component
library and an illumination component
library according to scene demand information; constructing a three-dimensional model according to the model component library and the scene demand information; and receiving dynamic configuration parameters of the illumination component library and the texture component library, and performing scene real-time rendering on the three-dimensional model. According to the method, the model component library, the texture component library and the illumination component library are matched, and the three-dimensional model is quickly built according to the model component library and the scene demand information, so that the complexity of modeling operation is reduced; the rendering effect of the three-dimensional model is updated in real time by analyzing the dynamic configuration parameters of the illumination and texture component library, so that visual effects under different illumination conditions are simulated in a virtual environment, the sense of reality of materials and surfaces is improved, rapid feedback and immediate adjustment of the design effect are ensured, and highly-customized and immersive user experience is provided.
