Construction and hierarchical display control method for 3D interactive villa type

Abstract

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.

Description

technical field [0001] The invention belongs to the field of 3D display, and more specifically relates to a method for constructing and controlling layered display of 3D interactive villa types. Background technique [0002] 1) The traditional villa sales display structure and unit type are usually displayed to consumers through renderings or physical sand table models. Its display effect is not intuitive enough, and it cannot be changed with the perspective of consumers. It cannot give consumers an immersive perception, let alone perceive the changed effect after changing a certain color tone or lighting. [0003] 2) In addition, the use of 3D architectural models is increasingly becoming an important content in the construction of digital cities and digital earth. How to rationally abstract the internal and external structures of buildings from the perspective of multi-detail and multi-level expression, and realize the integrated expression of 3D architectural interior an...
