The present invention relates to a web-based cyber model house, and in particular, a type of VR language that enables a provider and a consumer to bi-directionally communicate in real time on the web, which supplements the shortcomings of the existing panorama virtual reality. Web-based cyber model house implementation system and method using inturntool and JavaScript and suitable to implement cyber model house where consumers can select the finishing materials and preview in advance. It is about.

In general, consumers of existing sample houses have played a pivotal role in apartment selection. However, as the society came from the industrial society to the information society, each household was equipped with a high-speed leased line, and as of 2006, it became the fourth-largest IT powerhouse of high-speed Internet subscribers, with 26.4 persons per million among OECD countries.

The change of personality and personalization of consumers living in this information society was made by changing the purchasing method of Pangyo New Town, etc., and it is made by changing the form of sample houses in the future. The construction company introduced VR (Virtual Reality), a graphic data language that expresses 3D space on the Web, which can replace the functions of existing model houses to keep up with the changing needs of consumers.

However, this real-world-based Panorama VR (a program that allows you to rotate the 360 degrees around an axis and look at the entire photo through Zoom In / Out) is difficult to expect limited space creation, landscape and living information. The reality is that it is insufficient to meet consumer dispositions and needs.

In the prior art, first, classify and classify virtual reality, and consider a case study of previous studies. Second, it looks at the outline and advantages and disadvantages of the Virtual Reality Modeling Language (VRML). Third, the overview and advantages and disadvantages of Panorama VR format, which is the mainstream of the existing Cyber Model House, will be examined.

1. Overview of Virtual Reality and Previous Research

Virtual Reality is a combination of Reality and Virtuality, first named by Jarrow Lanier of VPL Research in the United States in 1989. This technology is a computer system that can be used as a pre-construction building or virtualized environment. It is to simulate the situation and to have a real experience and feeling.

Virtual reality can be said to be the reality that humans feel in the cyber space created by computers. It is a medium of 3D environment artificially created by computer that can freely search, adjust, and experience backgrounds and objects in real time.It can be divided into Impressive VR System, Desktop / Vehicle VR, Augmented Reality, etc. Prior Art Document Information [1] Yoon, Eun-Kyu, Lee, Jun-Kyu (2002), "A Study on the Application Characteristics of Virtual Reality Model House," Korean Institute of Interior Design Journal, No. 33, p.106.

Immersive VR is a virtual reality where users can wear basic equipment and completely immerse themselves in the three-dimensional space created by computer and experience and interact with the world defined in it. System. The Desktop / Vehicle VR method uses the traditional monitor screen as a perspective screen, and the Third VR format allows users to enter the room where the video camera is installed and communicate their movements to the camera to interact with the virtual objects created by the computer. This technique is shown again on the screen by the synthesis method ([2]). Desktop / Vehicle VR format is most commonly used in existing cyber model houses. When the Desktop / Vehicle VR format is divided into three categories, the panorama format using QTVR (Quicktime Virtual Reality) is most commonly used, and the format using X3D (Extensible Three Dimension), which is an alternative to VRML, is proposed in the present invention. Format using TURNTOOL etc. ([3])

Various virtual reality technologies are implemented in various forms in various fields according to each type.In architecture, it is used for communication between API (Application Programming Interface), operating system (OS) and application program composed of OPEN GL and DirectX in Korea. Study on virtual architecture simulation using game engine based on the language or message format ([4]), study on web-based participant model house based on X3D ([5]), internet virtual model house using QTVR Development research [6]. In the industry, Ssangyong is operating 3D e-catalogue through Showroom on the Internet homepage, and Sony Korea operates VAIO Notebook 3D e-catalogue through the internet homepage. Toyota Motor Co., Ltd. installed 'exclusive zone', a CAVE-type e-catalog, at the 2005 Seoul Motor Show, and realized each model's specifications such as the exterior color and interior of the vehicle through actual 3D simulation. Information provided. In broadcasting, augmented reality is used for soccer games, election broadcasts and weather forecasts. In medical field, special projector, 3D immersive head mounted display (HMD), virtual distance measurement system, automatic recording and stereo sound system, one-way mirror, are used for training of patients' social skills at Yonsei University Severance Mental Health Hospital. VR clinic using the back is running. In the field of research, Seemore, a visual supercomputing system, KISTI's immersive visualization system, has been in operation since 2003. CAVE operates Reality Studio at KIST's Video Media Center.

2. Cyber Model House using VRML

VRML (Virtual Reality Modeling Language) is a language for modeling 3D world, multimedia such as sound and video on the World Wide Web. It is a space where a large number of observers can experience the desired space directly as their intention wherever the Internet is connected by utilizing the Internet Virtual Reality (IVR) ([7]).

VRML is a language specification for displaying three-dimensional virtual space. Just as HTML (HyperText Markup Language) documents tag scripted files, VRML surrounds each object with a tag called a node. VRML is surprisingly simple compared to three-dimensional having a significant amount of data. Save the file with the extension * .wrl by entering the script in text format in the normal editor.

The 3D spatial description file (* .wrl) of the VRML format installed on the WWW server on the Internet is transmitted from the general user, and the text format data is converted into the 3D data from the VRML browser mounted on the computer of the VRML user. By rendering, the three-dimensional virtual space is displayed on the display. Accordingly, the displayed 3D virtual space can be moved and controlled through an input device such as a mouse operation or a keyboard. You can also link to an object in three-dimensional space, and by clicking on the object with the mouse, you can control the object and read two-dimensional HTML files.

In the architectural field, VRML can be used to efficiently advertise already-prepared buildings, and CAD (Computer Aided Design) data can be effectively utilized by using converters. In addition, VRML can be simulated for the building before completion so that users can virtually walk inside the building after completion. The use of VRML's technology proves that the virtual housing market can be fully realized. Products designed in places where CAD data transfer is relatively far away can be shown in advance to the client in three dimensions, reducing communication from lack of communication. In particular, the Internet makes it easier to exchange information with foreign countries, and can be used for overseas operations and design checks. In addition, it is expected that the field of application will be gradually expanded with the idea of everyone.

The advantages of VRML are: First, VRML has been recognized as a standard for representing 3D graphics on the Internet by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). .

Second, it supports image based 3D image and modeling based 3D.

Third, VRML can be freely expressed on the web by anyone with a free license.

Fourth, VRML does not require a special editor in the form of html, and can be written and edited in any text editor.

The shortcomings of VRML are first, the slow processing speed of VRML. Although VRML expresses it in an extremely simple format compared to the old three-dimensional data representation method, current network performance and rendering performance does not show satisfactory file loading speed. This may not be the direct responsibility of VRML, but it will also require the development of a more speedy architecture. Second, there are factors that reduce the user's immersion represented by the quality of the screen. Although VRML provides a mechanism for interacting with the virtual world, it is not yet satisfactory and requires the addition of many functions and improved performance.

3. Cyber Model House using Panorama VR

Panorama VR is a technology that allows you to experience image-based space on the web. Panorama VR's representative technology is QTVR, which is based on Quicktime, Apple's video processing technology. QTVR is based on photo still images.

1 is a conceptual diagram showing the operation principle of a conventional QTVR.

As shown in Fig. 1, the most commonly used is QTVR in Panorama VR format. QTVR has a center point in the same shape as shown in FIG. The camera at this center point is the viewer's view of the virtual space. From this point the viewer can see anywhere in the circular panorama. QTVR can produce the result on the basis of live-action, and in order to obtain a picture for a scene, it is necessary to rotate the camera at a predetermined angle and take a picture 360 degrees as shown in FIG. 2 ([6]).

2 is a conceptual diagram illustrating a photographing principle of a conventional panoramic VR camera.

The QTVR used in the conventional VR model house is composed of a simple six-sided cube that enables the virtual reality observer to view any room on the basis of due diligence due to the characteristics of the program. It is a form of putting a realistic picture on each side of the cube and watching as the camera rotates at the center point.

3 is a diagram illustrating an example of a conventional QTVR cyber model house.

Looking at the advantages of the QTVR cyber model house: First, QTVR is image-based and has lower latency than modeling-based web 3D technology.

Second, QTVR implements virtual reality with rendered photo images, which results in less computer load than other methods.

However, the shortcomings of the QTVR cyber model house are as follows.

First, the QTVR Cyber Model House can be manufactured only after the prototype house is built on the basis of due diligence. In addition, according to Article 8, Paragraph 2 (Operation of Cyber Sample Housing) of the Ministry of Construction and Transportation Notice No. 2005-397, cyber sample houses shall have a list of finishing materials and photographs for each material. However, in the case of QTVR, false information can be delivered based on live-action photography of sample houses.

Second, due to the nature of QTVR, the camera is fixed to the center point, so it can only rotate and slightly move up and down about the axis. In addition, when the edge of the corner is severe and the map is not a high-resolution image in a bitmap method, a crack occurs.

Third, QTVR attaches the 2D image to the 3D surface and constrains the surface so that the 2D image is strong and the space is weak.

Combining the features of the conventional VRML-based cyber model house and the Panorama VR-based cyber model house, it can be seen that there is a problem that the streaming time that a person can psychologically wait is long and the control is difficult in the virtual space. In addition, it is possible to produce only when offline sample houses are built on the basis of due diligence, which cannot take advantage of the cost saving characteristics, which is the advantage of cyber model houses, and puts a heavy burden on consumers.

Accordingly, the present invention has been proposed to solve the above-mentioned general problems, and an object of the present invention is to provide a bidirectional communication between a provider and a consumer in real time on the web, which compensates for the shortcomings of the conventional panorama VR. The present invention provides a web-based cyber model house implementation system and a method for implementing a cyber model house using an intern tool and JavaScript, and selecting a finishing material and previewing the quotation.

The object of the present invention is to focus on the supplier-centric characteristics of the conventional cyber model house through the analysis of the Cyber Model House based on QTVR (Quicktime Virtual Reality), which is a kind of Panorama VR format that is mostly used in domestic construction companies. Rather, he wanted to develop a user-centric web-based cyber model house.

This will be described in detail as follows.

1. Web-based Cyber Model House Implementation System

In the present invention, the virtual model house is made on a web basis, which means that various other multimedia elements that can be supported on the web can be utilized. Based on the VRML technology discussed so far, this article introduces an example of building a two-way cyber model house for users and administrators using TURNTOOL in real time on the web.

2. How to implement a web-based cyber model house

7 is a flowchart illustrating a web-based cyber model house implementation method according to an embodiment of the present invention.

This will be described in detail below.

2-1. Object Modeling and Mapping

Modeling is the first step in development. A virtual 3D model was created based on the arbitrary apartment design drawings. The production tool used Autodesk's 3DS max. TURNTOOL provides a 3DS max plug-in integrated interface, the most representative of 3D solutions, and is relatively easier to use than other VR tools and has a strong compression force, making it more natural to run on the web.

When modeling, the model was modeled on the basis of CAD for accurate proportion, and each module was manufactured for individual event control later. Also, for later database application, the name of the object is stored in a certain format in each unit.

FIG. 8 is a conceptual diagram illustrating an object modeling process in FIG. 7.

2-2. Lighting Plan and Render to Texture

In VR, lighting planning is an important factor in determining the quality of the result along with the Render to Texture. Illumination simulated artificial lighting and natural light using an IES (light distribution data file provided by a lighting company) file as shown in FIG. 9 and a radiosity solution (a technique for precisely calculating the mutual light reflection between objects).

FIG. 9 is a view illustrating an IES light distribution data file used in the lighting plan of FIG. 7.

Render to Texture was a matter of careful attention to the lighting data values on the Map. After several trials and errors, the most appropriate lighting value was found and applied to the map. Since the map plays a pivotal role in material change in future events, alpha channel and object name management were important. In the case of the material replaced after the appropriate lighting value and radiosity solution, Z-buffer (adjust the depth value between objects) was used to create the material to which the lighting value was applied.

FIG. 10 is a diagram illustrating an example of an IES file plan by 3DS MAX in the lighting plan of FIG. 7.

2-3. TURNTOOL event control and JavaScript control

TURNTOOL is able to exchange data between user and provider by interlocking database using JavaScript.

The supplier gave a few examples using TNTDoCommand (the string that executes the TURNTOOL command in the scene), and constructed a system that allows the user to go around and select the appropriate type to determine if additional selections are needed.

FIG. 11 is a diagram illustrating an example of a TNT script in HTML during turn tool event control and JavaScript control in FIG. 7.

3. Example of using web-based cyber model house

3-1. Running a web based cyber model house

12 is a view showing an example of a web-based VR model house homepage implemented by the present invention, Figure 13 is a view showing an example of an execution window of the web-based VR model house implemented by the present invention.

As shown in Fig. 13, when looking at the user interface of the web-based cyber model house, it is classified into three types: screen, finishing material, and quotation application window (see Fig. 12).

The upper part of the window was implemented using TURNTOOL as a virtual space experience place, and implemented two spaces, the main room and the living room.

FIG. 14 is a diagram illustrating an example of a screen window in a turn tool execution window in FIG. 13.

This virtual space is a part that can control the space with the user interface and experience the sense of space, and the material can be applied to the space in advance to be configured and visually checked according to the user's taste.

15 is a view showing an example of the finishing material window in the turn tool execution window in FIG.

So in the middle of the finishing material window is the part where the user directly selects the finishing material. Finishing materials were constructed by randomly selecting wallpaper and flooring materials of the parent company, which are widely distributed in the market. You can select this part and visually check it in the screen window. In the virtual space window where the user interface can be adjusted, the user can experience the sense of space according to the material so that the user's taste can be visually confirmed in advance.

FIG. 16 is a diagram illustrating an example of an interior quotation application window in the turntool execution window in FIG. 13.

In the interior quotation application window located at the bottom, the user can check the quotation value for the finishing material selected in the middle finishing material window. In the interior quotation application window, an estimate of the area of the virtual space and its area is created. Since the types of wallpaper and flooring materials are different, the estimate is applied differently when selecting each material. We have implemented a different summator. Therefore, by using the cyber model house implemented by the present invention, users can personalize their own space through the virtual model house according to their tastes and obtain estimates accordingly.

17 is a view showing an example including an estimate window as an execution window of the web-based VR model house implemented by the present invention.

On the other hand, when looking for the future development direction of the web-based cyber model house, it is difficult to construct a wide range of DBs due to limited DB collection. For example, a lighting company releases an IES file when it releases a light. IES file is a lighting DB file that is used as a basis for illuminance calculation in space simulation. On the basis of the IES lighting DB file, the embedded company will be able to release the embedded DB file such as the IES file. The supplier will be able to make various choices by constructing a huge DB and setting up the accurate accumulated price. In the case of lighting, it is also possible to plan interior lighting using Flash ActionScript and JavaScript.

As such, the present invention implements a cyber model house that uses a turn tool and JavaScript, which is a kind of VR language, to enable two-way communication between suppliers and consumers in real time on the web, and allows consumers to select the finishing materials and preview the quotation. Will be done.

As described above, the web-based cyber model house implementation system and method according to the present invention is a turn tool which is a kind of VR language to enable the communication between the provider and the consumer in real time on the web that compensates for the shortcomings of the existing panorama VR. Using JavaScript, it is possible to implement a cyber model house that allows consumers to select the finishing materials and preview the quotation.

First, the TURNTOOL-based cyber model house can save significantly on production cost and time compared to the photo-based QTVR, and can provide new kinds of information that QTVR could not provide.

Second, the biggest issue of the cyber model house is how similar it is to reality. The web, especially the TURNTOOL based cyber model house, has a greater sense of space than the real-world based QTVR, and reduces the selection error of consumers by material selection through the material selection window. There are advantages to it.

Third, the current offline sample home is a one-way way in which the supplier unilaterally shows the consumer. However, the web-based cyber model house proposed by the present invention is a cyber model house capable of two-way communication between a supplier and a consumer, and a wider choice of consumers than the conventional offline method and the QTVR model house. There is an advantage to see.

Although the above has been described as being limited to the preferred embodiment of the present invention, the present invention is not limited thereto and various changes, modifications, and equivalents may be used. Therefore, the present invention can be applied by appropriately modifying the above embodiments, it will be obvious that such application also belongs to the scope of the present invention based on the technical idea described in the claims below.
