Home interior design based on virtual reality technology of computer animation

HONG KONG, June 1, 2022 (GLOBE NEWSWIRE) – The WIMI Hologram Academy, working in partnership with the Holographic Science Innovation Center, has written a new technical paper describing their study of the application of computer animation technology, one of the VR technologies, in interior design. home design. This article follows below:

People are increasing their demands for quality of life, especially in home design, as China has developed rapidly in recent years. People want not only comfort, but also personalized personalization. The improved indoor effect and the reduced divergence between home design and the actual situation have become important research topics. Scientists from the WIMI Hologram Academy of WIMI Hologram Cloud Inc. (NASDAQ: WIMI) discussed how to provide new home interior design ideas based on virtual reality computer animation technology and a more intuitive view of the desired effect of home interior design. With the help of computer 3D virtual animation the corresponding 3D model is built. In the virtual reality of home design, users can use the simulation of the virtual interior design system to gain an intuitive understanding of the interior of the home and all kinds of decorations and furniture. In this case, it is more convenient for consumers to design their houses, thus further improving the quality and optimizing the effect.

By combining VRML with relevant programming scripts, we can build a realistic and practical virtual reality scene for users that can avoid the dilemma of designing a home by visiting the sample and depending on the imagination of users. The VRML language, based on Web3D technology, is used to design a home interior design framework based on virtual reality computer animation technology and to improve relevant interactive features to help people realize more convenient and efficient design. .

1.1 Condition quo of home interior design

At the moment when people furnish their new houses, they rely mainly on their imagination to decide the layout of the house and housing requirements. And they do not understand the specific arrangement of the space of the house. Usually clients and home design practitioners use plans to design the house and the client refers to drawings with a similar effect and some real photos. Although some home design companies will provide customers with relevant 3D animation, it is still difficult for them to gain an intuitive understanding of design. Often in the process of designing a home, the results differ significantly from customer expectations. At the same time, to help customers better understand the design, real estate developers will provide a guide for customers by creating housing models. However, this is a loss of labor and money, and its types and quantities are limited, making it difficult to meet different needs. Combining computer animation with virtual reality technology for home interior design not only saves resources, but also better meets the diverse needs of customers, which is the main trend in future research.

1.2 VRML-based VR home design

By analyzing the actual needs of users, VRML-based virtual reality home design must specifically achieve the following three functions.

(1) The personalized needs of the consumer must be met in the best possible way. Consumers should be able to search for specific information and the quality of different types of furniture and furnishings through the virtual reality home design system and make changes in home design, such as style, color, furniture, etc.

(2) Consumers must not only be able to have a holistic view of the effect of the interior design of the home through the design system, but also be able to move freely in different places in the room and perform virtual interaction. And they should be able to distinguish the functions of each part of the room at a glance.

(3) Users must be able to intuitively and quickly understand the relevant spatial scale, functional separation and traffic flow, etc., and have a relatively accurate understanding of the overall decoration effect when using the system. At the same time, users can make suggestions for personalized improvements based on their actual feelings, so that the design can be further improved before the actual work.

The analysis of the demand for VRML-based virtual reality interior design summarizes the relevant home design process.

2 Build the stage model

2.1 Content of the stage model construction

Home interior design based on computer animation technology with virtual reality is different from traditional interior modeling. With this system, the design model of all furniture must be as detailed as possible, while strictly following the actual dimensions of the drawings. The modeling includes the overall look and interior structure of the furniture. At the same time, relevant interactive operations should be added to make it easier for users to have a full roaming experience. The main objects for building a stage model are shoe cabinets, closets, cabinets, wall cabinets, windows, doors and other types of furniture. Independent MAX files must be created for these furniture and the corresponding WRL files must be generated in order to achieve more convenient modular operation and to optimize the interaction in the virtual scene.

2.2 Optimizing a scene model

To provide a more realistic virtual scene, it is necessary to display the virtual scene system in real time, usually at 12 frames per second or higher. Therefore, in the process of building the model, the model should be neither too rough nor too fine, but should be considered reasonably according to practical requirements. In particular, it should be built, as far as possible, in the form of landfill modeling to ensure that consumer requirements are met to the greatest extent possible and to avoid unnecessary waste. The design should reflect the details of the interior of the home and reduce the number of relevant surfaces.

3 Generating the main stage and its design

3.1 Integrating the main stage

In the home interior design system for virtual reality, the integration of the stage includes basic lighting, views and design of the model. Among them, the design of the model is key. At the same time, the relevant files of windows, doors and furniture must be independent and follow certain steps in the integration. In the plan, each piece of furniture or door can be recognized as a mass point and the coordinates of its spatial location are (Xn, Yn, Zn), and the corresponding VRML coordinates are (Xn, Yn, Zn) by combining the principles of the world coordinate system corresponding of VRML. The Inline node and the Transform node are then used to combine the interior furniture according to the given location coordinates to build the respective main stage. In this process, interactive operations such as pushing and pulling drawers, opening and closing the cabinet door must be encapsulated in the corresponding independent WRL files.

3.2 Perspective 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 viewpoint is determined by Orientation. In VRML, although many points of view can be defined, there is only one current point of view. At the same time, free switching between points of view is possible.

3.3 Implementation of interactive design

When users tour the interior through the virtual reality system, we want them to feel the actual space of the room and also to have a more detailed understanding of the interior. By roaming in cyberspace, users can change and adjust the style of the home and the position of the furniture in real time according to their own feelings, so as to achieve the effect of interior design that meets their needs. This function must be achieved through a well-functioning system. In particular, interactive features include modifying different styles of furniture, their layout and checking information.

In VRML, the placement of furniture is achieved by using a Transform2D extension unit. The units are rotated and geometrically panned. The switch unit is used to change the style of furniture and is used to record rotation, translation and modification of parameters made by the user by obtaining operational data, then entered into the database to make adjustments to home design.

3.4 Implementation of interactive animation

VRML should provide relevant interactive features and provide user-friendly animations when users interact with virtual reality. This makes VRML relatively attractive among other systems. A variety of interpolators and their corresponding time sensors are used to control the integrated scenes to make the corresponding VRML animations. In particular, in 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, and then interpolators are used to define the expected key of the generated nodes. through various animations. In general, the user definition of the animation is generated by the system using linear interpolation.

4. Conclusion

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