Method for union design and dispersion presentation to utilize CAD-VR system in Internet}

The present invention relates to a CAD-VR system on the Internet. More specifically, a single user or two or more users are created using virtual reality and CAD using a web browser or a dedicated browser on the Internet. Co-design using CAD-VR system on the Internet to make e-commerce through auction and reverse auction of architecture, interior, furniture, various materials, construction, sale, etc. And a distributed presentation method.

In the past, the seller set the price of the product by applying his / her own criteria, so that neither the seller nor the buyer could set an appropriate price, and only one method of auction or reverse auction was possible for one product.

In addition, it was possible to describe the product only with a picture or text, and even if there was a description of the three-dimensional product, the user could explain the three-dimensional product at an additional cost and effort. All parts had to be created and configured to show on the web.

It is impossible to express the product that the user wants to purchase only by general text or picture and cannot express the product which is not standardized unless it is produced by oneself. Only the user could buy the product.

In addition, the deal was made only for the products whose product information, such as form and function, were determined, and proceeded unilaterally without exchange of opinions between the buyer and seller until the deal was concluded.

Even though they could exchange opinions to make a deal between the buyer and the seller, they would have to exchange the opinions through general chat or 1: 1 in person on the web, and even if they used virtual reality, they would only show a simple three-dimensional effect.

In addition, even if the virtual reality was used, free movement and product information could not be transformed, and the CAD data could not be confirmed accurately, and even if the virtual reality or CAD were used, only one method could be used.

Even if virtual reality or CAD is used, the product can be described in only one way, and it is also limited to the defined product. For users to use virtual reality and CAD or a combination of virtual reality and CAD on the web, You had to download a dedicated browser or program from your service provider's site.

Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to present and navigate CAD data provided by a user or a service provider in real time, and to move to virtual reality. In addition, CAD and VR presentations can be performed using CAD-VR system that allows one or two or more people to exchange opinions through text chat and voice chat while working on CAD data or virtual reality presentation. It is to provide.

Another object of the present invention is to provide a joint design and distributed presentation method using a CAD-VR system on the Internet that can automatically calculate the cost of the construction to present the user convenience, trust between users and a reasonable price will be.

It is another object of the present invention to provide a co-design and distributed presentation method using a CAD-VR system on the Internet that can execute a program directly in a browser used by a user.

9A and 9B are flowcharts illustrating a method of operating the ezCAD DBMS according to the present invention.

Before a user who is connected to the Internet accesses a remote CAD-VR server to operate CAD and VR, it is checked whether one person will work privately or work on joint design and distributed presentation (S7050). .

After operating CAD-VR in single user mode, input new CAD drawings and VR design to modify the CAD drawings and change VR designs or make presentations in real time. The created CAD drawing and the VR design or the service provider searches for the CAD drawing and the VR design created for the member (S7100-S7140).

If there is a desired DB after the search, the process proceeds to the S7130, and if not, the process proceeds to the S7120 (S7150).

After inputting the S7130, the DB is stored in the DB and VR database systems to store or keep the DB, or the deleted DB is fed back to the S7110 or when the DB is not deleted, the process proceeds to the S7130 (S7160-S7180). ).

When a plurality of users connected to the Internet simultaneously access a remote CAD-VR server on the web to operate CAD and VR, or when the CAD-VR is inactivated and terminated, the process proceeds to the S1040, and when not finished, the feedback is returned to the S7100. (S7190-S7200).

By searching for another member who is working by using a service provided by a service provider, an ID of another member, an arbitrary room in operation and an arbitrary working room are searched for (S7210-S7230).

A member collaborates on a CAD drawing and VR design that another member is working on, and inputs a new CAD drawing and makes a VR design to modify the CAD drawing, change the VR design, or present in real time (S7240-S7260).

The member searches for the existing CAD drawings and VR designs or the CAD drawings and VR designs created by the service provider, and if there is a desired DB, proceeds to step S7250 and if not, enters new ones (S7270-S7290).

After the S7260 proceeds to the DB or VR database system to enter or continue to work, or after deleting the working DB or fed back to the S7290 or if the DB is not deleted proceeds to the S7260 (S7310-S7330) ).

When the DB and VR database systems are stored and finished, the process proceeds to the step S1040, and when it is not finished, it is fed back to the S7250 (S7340).

In this way, one or more members can text or voice chat, collaborate, and work on one or more CAD work and designs and presentations in VR. This can be viewed in real time on a web browser or a dedicated browser, and based on this, multiple members can auction or reverse auction sales.
