Technical Field
The invention relates to the technical field of intelligent operation and maintenance, in particular to an informationization and real-scene virtual simulation method for a building model.
Background
In the conventional building model display, a sand table is usually adopted for display. It can be understood that the sand table has poor effect on the detail processing of the virtual building space due to the constraint of the space when the virtual building (model) is displayed, and the building space simulation effect is poor due to the lack of effective rendering and animation presentation modes. The most classical application scenario is the sand table display of a community in the sales center of a large building. Due to the reasons, the sand table is difficult to truly present in buildings, green areas and public places, and in addition, another indoor display sand table is needed for indoor display, and even though the display effect is still far from that of real scenes (sample house) through the display.
