Rapid and Easy 2D and 3D Interior Design Method On The Wire and Wireless Internet}

The present invention relates to a drawing design method using a graphic system, and more particularly, to a method for conveniently creating two-dimensional and three-dimensional drawings in a wired / wireless Internet environment.

When interior design or drawing must be made, the CAD system or the image editing system should be used in the past, but it has been difficult to use, it takes a lot of time, and it has been difficult to use an additional 3D dedicated system for 3D work.

In order to create a floor plan in the prior art, a CAD system must first be used to create a two-dimensional plane in a conventional manner using basic menus such as line segments or arcs. Rooms, toilets, restaurants, libraries, etc. (hereinafter, collectively referred to as rooms), which are basically included in the two-dimensional plane, generally have a constant thickness and consist of four right-sided planes. The prior art has been pointed out as a problem that the use method is difficult and time-consuming because it has to take the way that each of the four sides having a predetermined thickness to be drawn to create such a room.

Next, in the prior art, only a part of the information created in 2D may be used to convert the 2D plan created as described above into 3D, and in order to add work in 3D again, a separate 3D dedicated CAD system should be used. Or using an image editing system. Therefore, it has been pointed out that the problem is that the use of several systems alternately, the method of using the system is difficult, the operation is impossible without the design experience, and the time is long and the size of the stored result becomes large.

Due to the problems of the prior art, there has been a demand for a method of providing all the above operations within a system and provided on the web so that anyone can work easily and quickly anywhere.

In addition, a two-dimensional detail drawing and a three-dimensional virtual drawing are required for complete detail of the building structure. The two-dimensional drawing design uses a two-dimensional CAD program (for example, AutoCAD or UniCAD). To do this, use a 3D rendering program (eg 3D Studio MAX). By the way, according to the prior art, there is a problem that the two-dimensional conceptual design which is the basis of the two-dimensional detailed design and the three-dimensional conceptual design which is the basis of the three-dimensional virtual photorealistic drawing must be separately produced.

The present invention has been made to solve the problems of the prior art, it is possible to complete a two-dimensional floor plan by performing a simple operation in two dimensions in a wired / wireless Internet environment and automatically converts the completed two-dimensional drawings to three-dimensional It is an object of the present invention to provide a 2D / 3D drawing simultaneous design method for completing a three-dimensional stereoscopic view.

In addition, an object of the present invention is to provide a 2D / 3D drawing simultaneous design method that can be connected to the 2D detailed design work and 3D virtual due diligence work from the 2D / 3D drawing created using the 2D / 3D drawing simultaneous design method.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flow chart schematically showing each step of the plan view design method of the present invention.

As described above, the present invention provides a design method for conveniently creating a 2D / 3D drawing on the Internet.

First, as a first step, an external wall that is the basis of an interior object is generated (S110).

For example, the generation of a room having four sides (walls) having a predetermined thickness will be described with the drawing work for the four walls as described above. In other words, the four points forming the four sides are inputted, connected to the points and the points, and given a predetermined thickness, four walls have been taken.

In contrast, the present invention provides a method of creating a room consisting of four walls having a predetermined thickness with only two point inputs.

2A to 2D are diagrams for explaining a wall generating method of a two-point input method according to the present invention. First, as shown in FIG. 2A, two points are input from the user to specify two points in a diagonal direction among four corners of the room so as to create two points, that is, a room having a desired shape and size.

Based on the two selected points, find the width and length of the room. As shown in FIG. 2B, when the first two points selected by the user are P ₁ and P ₂ and the other two points are P ₃ and P ₄ , the equation for calculating the width and length of the room is as follows.

sizeX = | (P₂- P₁) R | (Where sizeX is the width of the room, R = (1,0))

sizeY = | (P₂- P₁) N | (Where sizeY is the length of the room, N = (0,1))

Subsequently, the remaining two points (P ₃ , P ₄ ) of the four points forming the room are derived by the following equation.

P₃ = P₁ + sizeY * N

P₄ = P₁ + sizeX * R

When four points are determined in this way, these four points are connected to form a room of a predetermined thickness.

In addition, the present invention can be configured to show the width and height information to the user when the width and height is obtained by the equation (1), so that the user can modify the width and height as desired. That is, for example, a chat room as shown in FIG. 2C may be provided to notify the width and length, and a desired length may be input to the width and length columns.

When the new horizontal length (sizeX ') and the vertical length (sizeY') are input, P2 is changed, and then the room is determined by deriving the remaining points by the above equation (2).

The equation for determining the new P ₂ (called P ₂ ') from the width and length of the room is:

P ₂ '= P₁ + sizeX' * R + sizeY '* N

Regarding the wall thickness, for example, a desired thickness may be selected and input by the wall thickness check box provided in the chat room of FIG. 2C, and the wall thickness may be configured to include the obtained four points and to have a selected wall thickness.

FIG. 2D shows an example of the creation of a room with four walls having a predetermined thickness created by the two point input of FIG. 2A.

Next, in order to complete a single floor plan, since a plurality of rooms or wall structures are usually completed, additionally, a plurality of other wall structures included in or connected to a side of a room (wall structure) generated in the above-described manner must be additionally generated. do.

3 is a preferred example of a two-dimensional floor plan in which room creation is completed by the method of the present invention, showing a plan view of an apartment consisting of a combination of a plurality of rooms and an interior space such as a living room.

Referring to the drawing, when creating a new room, a room or wall that overlaps or connects to an already created wall is configured to create only the remaining wall (face) smoothly by using an existing wall instead of creating a new wall (face). You can create any plane. That is, the room 300 corresponding to the whole is first generated, and then additionally generated rooms 310, 320, 330, 340, and 350 to represent other rooms. At this time, the walls may be connected to each other or broken. For example, in the case of a room 350 having a different material or structure from an adjacent wall, the wall may be separated from the adjacent wall.

The present invention may further comprise the process of creating a continuous wall.

Since the room generating method is capable of forming only a right angle wall or a closed room structure, it is preferable to provide a method of continuously generating a continuous wall, that is, a straight wall consisting of two points or an arc wall consisting of three points. At this time, the room or wall overlapping or connected to the generated wall is automatically connected.

For example, a circular arc wall will be described in more detail. First, three points of a start point, an end point, and an intermediate point are input from a user, and the points are connected to generate an arc. Set the length, thickness, and height of the next wall. 4 shows an example of a dialog box provided when creating a continuous wall according to the present invention. Finally, create an arc wall with a set length, thickness, and height. The creation of a straight wall of two points is also carried out in the same way.

As a second step, a door or window is inserted (S 120).

Select the image of the door or window you want in the system and drag and drop it to the desired position to insert it. Since most doors and windows are created on the wall, the inserted wall is automatically drilled by the size or thickness of the door or window. In this case, the door or window brings the already defined contents. In the two-dimensional state, only the two-dimensional contents are imported and the three-dimensional contents are replaced by the three-dimensional contents by referring to the information on the corresponding three-dimensional contents in the database.

Next, as a third step, a floor and a ceiling are generated (S 130).

When the system selects the desired floor or ceiling material and places it in the desired location by dragging and dropping, it automatically searches for the walls surrounding the location and creates an outer boundary that forms the floor or ceiling. Provides a way to create a ceiling. The ceiling is made by raising the wall from the floor, but it is not visible in two dimensions.

5 is a reference view for explaining an example of the floor generating method according to the method of the present invention. Referring to the drawing, if a desired material is selected from the menus 510, 520, and 530 of the menu box 500 provided in advance and dragged to the desired part of the plan view, the boundary around the dropped point is automatically extracted and the drop point The interior of the closed curve that surrounds is transformed into the bottom 360 of the selected material 510. By dragging and dropping with a mouse like this, all rooms or living rooms can be converted into floors of a desired material.

As a next fourth step, the two-dimensional plan generated in this way is converted into three-dimensional (S 140).

When the two-dimensional drawing generated in the above three steps is converted into three-dimensional, the wall forms a three-dimensional shape having a predetermined thickness, length, and height. In the case of doors or windows, they are replaced with 3D content stored in the database and displayed on the screen. 6 and 7 show an example of a two-dimensional plan view and a corresponding three-dimensional plan view generated by the method of the present invention.

As a final fifth step, the two-dimensional plan and the three-dimensional stereogram are stored as a file or image of a specific format (S 150).

The created drawings may be stored in a self-defined format, and the 2D plan and 3D stereograms may be stored as a single file. Two-dimensional and three-dimensional stereograms stored in a single file will be referred to simply as 2D / 3D drawings. In addition, the present invention can be configured to store only two-dimensional data and position information in consideration of the size of the data. According to such a configuration, since only two-dimensional data and location information are stored and subsequently read, the three-dimensional data is generated from the stored two-dimensional data and location information, so the storage capacity is very small, and the storage and transmission on the Internet are efficient. It can also be saved as an image so anyone can easily see the result.

The 2D / 3D drawing functions as a conceptual design drawing, and in reality, the design of a building structure cannot end in the conceptual design and should lead to 2D detailed design work and 3D virtual due diligence work. However, it is not possible to add the functionality of detailed design and virtual due diligence to the system of conceptual design. Not only does it fit the characteristics of the system, but it is also complicated and difficult to use for users.

In the case of the 2D detailed design, the details of the facilities such as the electrical wiring, piping, and heating, as well as the design of the structure, must be included in the drawings, which is complicated enough to make it without all the functions of the 2D CAD program. Virtual photorealism in 3D is too complex to create without knowledge of the modeling capabilities and layout of 3D rendering programs, but it requires a sense of design to render it closer to photorealistic rendering. As these two programs have different uses or usages, it is impossible to integrate the two programs, but it is meaningless. Also, it takes a lot of time and money to write well, so it's not easy to write both. For this reason, programs that produce detailed schematics and virtual photorealistic drawings have to use dedicated programs.

Therefore, in the prior art, detailed drawings were produced with a 2D CAD program and 3D virtual photorealistic drawings had to be produced separately with a 3D rendering program, which was inefficient and time consuming. Accordingly, the present invention further provides a method of converting a file format of a conceptual design file based on the 2D / 3D drawing, so that a detailed design drawing and a virtual photorealistic drawing can be directly produced from the 2D / 3D drawing.

Since all three systems are different, drawing conceptual, 2D detailed, and 3D virtual designs can be several times more expensive and costly, and ensure the consistency of data (e.g., location, color, size, etc.). Problems can arise. However, if the drawings from the conceptual design are used in both the detailed design and the 3D virtual photorealistic drawing, it can save a lot of time and money, and at least ensure the data consistency of the conceptual design.

Specifically, the format of a 2D / 3D drawing file is first converted to a dwg or uniCAD mdw file format for 2D detailed drawings, and then a 3D rendering program for 3D virtual photorealistic drawings. The 3Ds file format in 3D Studio MAX can be used to convert detailed drawings to complete detailed designs and virtual photorealistic drawings using their own unique features in each program.

8 is a conceptual diagram of a 2D detailed view and a 3D virtual photorealistic drawing method according to a conventional method. As you can see, it can be seen that drawing from the beginning in 2D CAD programs and 3D rendering programs is quite inefficient.

9 is a conceptual diagram of a 2D detailed design and 3D virtual photorealistic drawing method according to the method of the present invention. Referring to the drawings, according to the present invention, since 2D / 3D drawings, ie, 2D detailed schematics and 3D virtual photorealistic views, are created from conceptual designs, except for parts that require extremely detailed precision. Improvement can be seen.

FIG. 10 is a view for explaining a file format conversion method from a 2D / 3D drawing according to the present invention to a file for a 2D CAD program (for example, UniCAD) and a 3D rendering program (for example, 3D Studio Max).

The 2D / 3D drawing of the present invention is a line object representing a straight line, an arc object representing an arc or a curve, a wall object representing a wall, for example, a door, a window, a furniture, a TV. , 2D symbol objects representing beds, closets, etc. as 2D and 3D symbols, and 3D symbol objects and layer objects for convenience by grouping certain objects and maintaining their properties. .

First, a file format conversion method of a 2D / 3D drawing file into a detailed design file includes the following object conversion process. Among the objects constituting the 2D / 3D drawing file, the line object, the arc object, the wall object, the 2D symbol object, and the line object, the arc object, and the layer object, which have planar properties with respect to the two-dimensional plan, are the same type. Keep it. Since the wall object with the following three-dimensional properties consists of a line object and an arc object in a plane, it is separated into a line object and an arc object through an explode process. For the 2D symbol object, one of the method of maintaining the symbol shape as it is and decomposing the line object and the arc object may be selected. As described above, the file format is changed to a 2D detailed design file using a predetermined library required for converting the object and converting the file into a corresponding 2D program file.

The file format conversion method of the next 2D / 3D drawing file into the virtual photorealistic file includes the following object conversion process. Among the objects constituting the 2D / 3D drawing file, three-dimensional attributes are wall objects, 3D symbol objects, and layer objects. The double wall object is converted into a mesh object by converting the mesh data into a mesh object for the three-dimensional surface composition, and it is preferable to change it into a triangular mesh mesh object consisting of a mesh of a triangle shape. For the next 3D symbol object, it is decomposed and mashed into a mesh object. For the next layer object, keep it the same and change it to a group object. As described above, the file format is changed to a 3D virtual photorealistic file using a predetermined library required for converting the object and converting the file into a corresponding 3D program file.

Based on the format-detailed detailed design file and the virtual photo-realistic file, the 2D and 3D dedicated programs are used to complete the detailed design and the virtual photorealistic drawing. In other words, a detailed 2D CAD program file is added to the file format for the converted 2D CAD program, and detailed construction information such as wall details, piping, electrical wiring, heating, and water supply and drainage are created. The final virtual photorealistic view is created by adding operations such as high quality texture mapping or ray tracing rendering such as lightmap. FIG. 11 shows an example of a conceptual design diagram in 3D form among 2D / 3D drawings, and FIG. 12 shows a virtual photorealistic view completed using a file converted from the 2D / 3D drawings of FIG. 11.

It will also be understood that various modifications and variations can be made by those skilled in the art without departing from the spirit and scope of the invention.

According to the configuration of the present invention as described above, it is possible to simply design the two-dimensional and three-dimensional drawings of the floor plan required for the interior design work without special education or knowledge.

In addition, according to the present invention, it is possible to obtain an effect that it is possible to provide a design method capable of easily and quickly interior design and 2D and 3D drawing work without additional work in another system.
