The selection of sample materials directly affects the use function and appearance quality of the project. However, at present, the material selection and finalization process is presented in the form of material photos or decoration renderings. Due to poor display effect and insufficient overall consideration of various material selections, the material selection and finalization process needs to be repeatedly confirmed, the cycle is lengthy, and even the construction period is delayed.

S3, import the model after material integration into the panoramic software, perform panoramic rendering and scene interaction, and generate a panoramic scene with material replacement interaction; S4. Provide the panoramic scene to the sample confirmation parties, interactively select materials on the panoramic model, and finalize the sample at one time.
