[0065] The roof object modeler obtains the roof polygon node coordinates group_draw_roof and the ceiling polygon node coordinates group_draw_ceiling from the drawing plane node picker, and projects the roof polygon node coordinates group_draw_roof and the ceiling polygon node coordinates group_draw_ceiling respectively t...

Embodiment 3

[0075] Step 1. Pick up the polygon node coordinates.

[0076] The drawing plane node picker captures the coordinates of each node of the roof polygon and the node coordinates of the ceiling polygon drawn in the drawing plane, and records them in the order of operations, assuming that the coordinates of the roof polygon nodes recorded from the drawing plane are group_draw_roof and the polygon node coordinates of the ceiling are group_draw_ceiling; the way to draw the plane node picker to capture the polygon vertex coordinates of the roof and ceiling can be, but not limited to, be obtained from the operation interface of the computer or mobile device or by file import. The recording method of the polygon vertex coordinates of the suspended ceiling can be but not limited to the cache method of array or linked list;

[0077] Step 2. Build an information model.

[0078]The roof object modeler obtains the roof polygon node coordinates group_draw_roof and the ceiling polygon node co...

The method and the system can realize the purposes of drawing one or more arbitrary polygons in a roof polygon of a two-dimensional design planar graph and directly generating the suspended ceiling 3D model, and are high in efficiency, low in cost and easy to promote.

Description

technical field [0001] The present invention relates to the field of 3D model design, more specifically, to a system and method for generating a 3D model of a suspended ceiling based on a drawing plane polygon. Background technique [0002] The suspended ceiling is an important part of the overall living room, so the design of the suspended ceiling occupies a very important position in the entire living room decoration. At present, the 3D design and modeling capabilities for suspended ceilings are generally provided in professional 3D modeling software such as 3D MAX and CAD. With the improvement of people's knowledge level and the development of Internet informationization, consumers hope to improve themselves For this reason, consumers are required to learn professional knowledge such as 3D MAX and CAD. The cost is very high. Therefore, reducing the operational difficulty of ceiling 3D design and modeling to meet the DIY demands of ordinary consumers will be Technological...
