Building Integrated Information System using Modeling - based VR}

The present invention relates to a system for providing comprehensive building information using modeling-based VR. More specifically, it relates to a building comprehensive information providing system using a modeling-based VR that provides a virtual reality 3D building including sunlight information by time and date of the building through a user terminal.

Recently, as virtual reality technology has reached the level of commercialization under the influence of digital technology development and cost reduction, the demand for digital virtual space is increasing more and more steeply. Dynamic experience of digital virtual space in all business areas is being newly applied and pioneered as a new business model.

However, the content cannot keep up with the current pace of development of VR equipment, both qualitatively and quantitatively. However, in the exhibition field including architecture, the concept of virtual space experience has been applied for several years, and the demand is steadily increasing as one of the essential elements in the building sale market.

Also, in general, a model house is a pre-built model house to show to people who want to buy a house when building such as an apartment building.

The production of the model house is to sign a tenancy contract by recruiting people who want to buy a house before the apartment the builders are building is completed.

The model house is recently operated in virtual reality. The model house through virtual reality is highly realistic and provides buyers with an interior view that is close to reality so that they can check how the space is divided.

And people who want to buy a house want to check the exterior, that is, the exterior view, usually seen from the floor where they bought it.

The reason why a person who wants to buy a house wants to check the external view is that the external view is different for each dong and floor, which are the location of the building.

In other words, people want to check that the external view is different for each building and floor where the room is located.

The reason that the external view varies by building and floor is that the light enters for a short time or the exterior of the sea or mountain is covered depending on the location of the building corresponding to the building and the height of the room. because it happens a lot.

The conventional system for providing an external view does not provide the amount of sunlight or the view according to the date and time, so there is a problem that a person who wants to purchase a house cannot know the exact amount of sunlight and the view.
