Description

Modeling method for traditional grille and recording medium for the same}

The present invention relates to a traditional window technology, and more particularly, to a method for modeling a traditional grate having various forms and a recording medium therefor.

Korean traditional windows are made by inserting a grate into a frame having various shapes, such as a wooden frame, and then adding hanji on it. These traditional windows have several features:

First, because the hanji that is added to the grate, that is, the window paper does not withstand the weight of the grate for a long time, the grate must be firmly supported by connecting to the outer frame of the window.

Second, if the space between adjacent grate, that is, the space where only one exists, becomes too wide, the space between the grate should not be too wide or too narrow because the paper is easy to tear.

Third, the grate has a geometrically symmetrical structure for the aesthetic appearance of the window. At this time, the symmetrical structure of the grate refers to a shape that is point symmetrical or line symmetrical from the reference point or reference line.

Because of the characteristics of the traditional windows as described above, the conventional windows are manufactured manually by a person (technician).

The present invention is to provide a traditional grate modeling method that can automatically model the grate of the traditional window having a variety of forms.

In the traditional grate modeling method according to an embodiment of the present invention for solving the above problems, the step of defining a plurality of grid points on each side of the window frame and a plurality of grate defined according to one grate type selected from a plurality of grate forms Generating a virtual grate shape using an extension line extending from each of the grid points of.

The traditional grate modeling method of the present invention and a recording medium therefor have the effect of automatically modeling and generating various grate types of the traditional window, thereby producing a standardized traditional window.
