“…In addition, computer science and technology have changed the methods of traditional architectural design, especially with virtual reality technology (VR), which has become the most likely technology to change the world in the 21st century. Virtual reality technology integrates computer graphics and arti cial intelligence to provide users with realistic images, sounds, and virtual environment simulation, so that users can truly feel integrated into the physical environment [1]. Generally, a realistic and real three-dimensional simulation environment is created through interactive software and hardware, and then the user can touch the environment like the real environment by using body movement.…”

In order to improve the effect of distributed 3D interior design, a distributed 3D interior design method based on color image model is proposed in this paper. In this paper, the author uses the distributed feature information fusion method to construct the color image model of the distributed 3D interior design, and carries out edge contour detection and feature extraction for the distributed 3D interior spatial distribution image. The RGB color decomposition method is used to decompose the color pixel features of the three-dimensional indoor spatial distribution image. Combined with the three-dimensional point cloud feature reorganization method, the color space reconstruction of the distributed three-dimensional interior design is realized, and the optimal combination of color features of the distributed three-dimensional interior design is realized. Based on the design of image and color processing algorithm, the development and design of distributed 3D interior design system is carried out based on virtual reality and visual simulation technology. The 3D modeling of distributed 3D interior design is carried out using 3ds max, and the indoor hierarchical structure design is realized using the modeling software Multigen Creator. The experimental results show that, according to the color information fusion results, the distributed 3D interior design optimization is realized. Compared with the traditional manual design method, the root mean square error of this method is greatly reduced from 0.232 to 0.023, and the time cost is 82.8% faster. This method has a better visual effect and strong feature expression ability. Conclusion. The visual effect of distributed 3D interior design with this method is good, the error is small, and the visual expression ability is strong.

“…Zhang and others think that in the process of 3D indoor scene synthesis based on style consistency, the furniture model in the final synthesized scene should not only be the same in the type of home style but also reflect the compatibility and coordination of materials and colors between furniture [6]. However, Dong and others said that in the field of computer graphics and computer vision, the relevant methods of scene synthesis and layout design usually only consider the semantic information of furniture without constraints on the style of synthetic scenes [7]. The scene is a reasonable imagination based on the actual situation of the space, and it is a reasonable experience based on the designer's true feelings in the situation.…”

In order to solve the research problem of collaborative retrieval 3D indoor scene synthesis system, an automatic synthesis method of 3D indoor scene is proposed. In the research fields of computer graphics and computer vision, the modeling of various 3D scenes has always been a hot spot and a very valuable research topic for Chinese and foreign scholars. GMM is used to fit the position of the object on the support surface, and the position distribution model is obtained. Firstly, a file is created to store the normalized position of the counted object on the support surface. The number of coordinates represents the number of times the object appears in the scene library. Then, the Gaussian mixture model is used to fit the content of the file to obtain the location distribution model. For the initial indoor scene and the description of small objects to be added to the scene given by the user, select small objects with the help of the material library. Shapenetcorcv2 is the core part of the database, with a total of 55 categories and more than 50000 model instances. The automatic placement of these small objects is realized by using the scene synthesis algorithm, which shows the continuous enrichment of the evolution process of simple scenes to solve various problems of 3D indoor scene modeling. This method not only reflects the design requirements of users but also avoids cumbersome manual operation.

This article proposes a computer network security defense system model based on multisource big data, which makes the security of computer networks more complete because of the shortage of current computer network security defense systems. The current network security situation is analyzed, and the problems faced in the field of network security are pointed out; then, multisource big data is introduced, and the characteristics of the multisource big data model are analyzed. This article proposes an information system network security model, which formally describes the relationship between network behavior among nodes, security threats, network attacks, and defense capability of security devices in an information system. After that, a network security defense system measurement scheme is constructed based on hierarchical analysis, and quantitative indicators of defense effectiveness are defined in two dimensions: risk severity of security threats and defense response actions of security devices, which enables quantitative evaluation of the security defense system, and then identifies omissions and defects of the network security defense system. A defense system measurement and optimization system is designed based on the proposed network security system measurement and optimization scheme. The application analysis of the project is combined with the actual scenarios. Through the evaluation and optimization of the security defense system in the natural methods, it is proved that the network security defense system evaluation and optimization scheme proposed in this article has reasonableness and effectiveness in the actual application.
