The invention, which belongs to the 3D display field, discloses a construction and hierarchical display control method for a 3D interactive villa type. The method comprises: step one, preparing relevant data of a two-dimensional plane CAD survey map; step two, carrying out construction and integration of a three-dimensional building
element model; to be specific, step 2.1, carrying out construction of a villa model type and an external vertical face; step 2.2, carrying out shadow baking on a building external vertical face and an outdoor model; and step 2.3, carrying out integrated guiding of a three-dimensional building
element model; and step three, carrying out controlling and displaying of a three-dimensional villa building hierarchical model. According to the invention, with the existing two-dimensional plane CAD survey map of the
urban building, an internal-external integrated model of the building is constructed by using the 3D technology, thereby realizing three-dimensional villa
model building and hierarchical display control as well as user interaction in a three-dimensional field. The provided method is suitable for fields of the
building design, the villa house displaying, and 3D house selling and the like.
