Home interior design based on

HONG KONG, June 01, 2022 (GLOBE NEWSWIRE) — WIMI Hologram Academy, in partnership with the Holographic Science Innovation Center, has written a new technical paper outlining their exploration of the application of computer animation technology, one VR technologies, in the interior design of the house. This article follows below:

People are increasing their demands on quality of life, especially in home design, as China develops rapidly in recent years. People don’t just want comfort, but also personalized customization. Improving the interior effect and narrowing the gap between the house design and the actual situation have become important research topics. Scientists from the WIMI Hologram Cloud Inc. (NASDAQ: WIMI) WIMI Hologram Academy discussed how to provide new ideas for home interior design based on computer animation virtual reality technology and a more intuitive view of the desired effect of home interior design. Using virtual 3D computer animation, the corresponding 3D model is built. In the virtual reality of home design, users can use the virtual interior design system simulation to get an intuitive understanding of the home interior and all kinds of decorations and furnishings. In this case, it is more convenient for users to design their houses, thus further improving the quality and maximizing the effect.

By combining VRML with the corresponding programming scripts, we can create a realistic and practical virtual reality scene for users, which can avoid the dilemma of designing a house by visiting the sample and according to the imagination of users. VRML language, based on Web3D technology, is used to design home interior design framework based on virtual reality computer animation technology and improve corresponding interactive functions to help people realize a more practical and efficient design.

1.1 Status what interior design of the house

Nowadays, when people furnish their new homes, they mainly rely on their imagination to decide the layout of the house and the residential requirements. And they are unclear on the specific layout of the house space. Usually, clients and house design practitioners use blueprints to design the house, and the client refers to similar effect drawings and real pictures. Although some house design companies provide customers with the corresponding 3D animation, it is still difficult for customers to have an intuitive understanding of the design. Often in the home design process, the results differ greatly from the clients’ expectations. At the same time, to help customers better understand the design, property developers will provide reference to customers by setting up model houses. However, it is a waste of labor and money, and its types and quantities are limited, which makes it difficult to meet various needs. The combination of computer animation with virtual reality technology for home interior design not only saves resources, but also better meets various needs of customers, which is the main trend of future research. .

1.2 VRMLvirtual reality based house design

Through the analysis of users’ actual needs, the VRML-based virtual reality home design should specifically realize the following three functions.

(1) The user’s personalized needs should be met as far as possible. Users should be able to query the specific information and quality of various types of furniture and furnishings through the virtual reality house design system, and make changes to the house design, such as style, color, furniture, etc.

(2) Users should not only be able to see the overall view of the interior design effect of the house through the design system, but also be able to move freely to various places in the room and create virtual interaction. And they should be able to discriminate the functions of each part of the room at first sight.

(3) The user should be able to intuitively and quickly grasp the corresponding spatial scale, functional partitioning, traffic flow, etc., and have a relatively accurate understanding of the overall effect of decoration when using the system. At the same time, users can make personalized improvement suggestions according to their actual feelings, so that the design can be further improved before the actual operation.

Through the VRML-based virtual reality house interior design demand analysis, the corresponding house design process is summarized.

2 The construction of the scene model

2.1 Stage model content construction

Home interior design based on virtual reality computer animation technology is different from traditional interior modeling. In this system, the design model of all furniture should be as detailed as possible, while strictly adhering to the actual dimensions of the drawings. The modeling includes the general appearance and the internal structure of the furniture. At the same time, the corresponding interactive operations should be added to allow users to have a full roaming experience. The main objects for the construction of stage models are shoe cabinets, closets, cabinets, wall cabinets, windows, doors and other types of furniture. For these pieces of furniture, independent MAX files should be created and corresponding WRL files should be generated to achieve more convenient modular operation and optimize interaction in the virtual scene.

2.2 Optimization of the scene model

To ensure a more realistic virtual scene, real-time rendering from the virtual scene system is required, typically at 12 frames per second or higher. Therefore, in the process of building the model, the model should not be too coarse or too fine, but should be reasonably considered according to practical requirements. Concretely, it should be built as far as possible in the form of polygonal modeling, to ensure that user requirements are met as much as possible and to avoid unnecessary waste. The design should reflect the details of the interior house and reduce the number of corresponding surfaces.

3 The generation of the main stage and its design

3.1 Main Stage Integration

In the virtual reality house interior design system, the scene integration mainly includes lighting, point of view and model design. Among them, the design of the model is the key. At the same time, the corresponding files of windows, doors and furniture should be independent and follow certain steps when integrating. In the plan, each piece of furniture or door can be recognized as a mass point, and its spatial location coordinates are (Xn,Yn,Zn), and the corresponding VRML coordinates are (Xn,Yn,Zn) by combining the principles of world coordinate system corresponding to the VRML. Then the Inline node and the Transform node are used to combine the interior furniture based on the given location coordinates to create the corresponding main scene. In this process, interactive operations such as pushing and pulling a drawer, opening and closing a cabinet door must be encapsulated in the corresponding independent WRL files.

3.2 Viewpoint design

Once the main scene is integrated, the position of the viewpoint corresponding to some of the scenes that the user can use must be defined by Position, and the orientation of the camera’s point of view is defined by Orientation. In VRML, although multiple viewpoints can be defined, there is only one current observer viewpoint. At the same time, it is possible to switch freely between viewpoints.

3.3 Implementation of interactive design

When users walk through the interior space through the virtual reality system, we want them to feel the real space of the room and also have a more detailed understanding of the interior house. By moving through the virtual space, users can real-time change and adjust the style of the house and the position of the furniture according to their own feelings, so as to achieve the interior decoration effect that meets their needs. This function must be carried out thanks to an efficient system. Specifically, interactive features include changing different styles of furniture, placing them, and checking information.

In VRML, furniture placement is achieved using the Transform2D extension node. Nodes are rotated and panned geometrically. The switch node is used to change the style of the cabinet, and it is used to record the rotation, translation and parameter change made by the user by obtaining the operation data, and then it is entered into the database to make corrections to the house pattern.

3.4 Setting up interactive animation

VRML should provide corresponding interactive functions and provide comfortable animations when users interact with virtual reality. This is what makes VRML relatively attractive among other systems. A variety of interpolators and their corresponding time sensors are used to control the built-in scenes to create the corresponding VRML animations. Specifically, in the VRML animation, the time sensor is defined as a clock generator, whose main role is to control various time parameters such as interval, end time, and start time. , then interpolators are used to set the expected key of the generated nodes. by various animations. In general, the user definition of the animation is generated by the system using linear interpolation.

4. Closing

In this article, computer animation is applied as the basis for interior house design and performs 3D modeling using VRML language to achieve highly restored interior house design effects. We can see that it is simple and convenient, the cost is reasonable, and it is conducive to practical applications. The system can adjust the parameters and position of various home furniture in the home design, so as to provide real space layout effect. At the same time, the comprehensive interactive functions also provide greater convenience for users to achieve better home design.
