Embodiment Construction
[0061] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments.
[0062] A BIM-based parametric modeling method for special-shaped roof tiles imitating Tang and Song ancient buildings, including the following steps:
[0063] Step 1. Construct the overall surface of the roof through the mass frame lines, such as figure 1 shown;
[0064]Step 2: Establish roof tile separation, the purpose of which is to divide the entire roof into grid units corresponding to the position of each tile, and then replace it by the created adaptive parameterized roof tile family association. This step is the core key step of the present invention, and concrete operation is as follows:
[0065] Before establishing the roof tile separation, the parametric roof tile family is first defined by two formulas:
[0066] 1. First create a four-sided characteristic Bezier surface
[0067] Parametric surface modeling uses...

The invention relates to a BIM (Building Information Modeling)-based parametric modeling method for imitated Tang and Song dynasty ancient building special-shaped roof tiles. According to the method, curved surface vector tangent lines of curved surface adaptive characteristic points are generated through a Bezier curve formula and a Bezier curved surface variable formula; roof cylindrical tile members are associated to form parametric roof cylindrical tile groups; a roof structure plane is generated by establishing a roof structure volume; the roof structure plane is divided by utilizing a UV coordinate system to form spatial adaptive point grid units corresponding to cylindrical tiles; and the cylindrical tile groups are loaded and the grid units are associated to form a roof. In addition, the parametric modeling work of the ancient building special-shaped roof is optimized, so that the repeated work of ancient building roof modeling is reduced; and the three-dimensional effect of shape and size under a corresponding parameter setting condition is displayed instantly, and the design is visual, so that design personnel can perform quick modeling quickly. Furthermore, the method is reasonable in design and ingenious in concept, the working efficiency is effectively improved, and the modeling is visual, so that the method has wide promotion and application values.
