Immersive Experience and Interactive Design of Architectural Visualization Based on Virtual Reality Technology

In order to provide a more immersive and interactive experience, a new VR rendering algorithm suitable for architectural design has been developed in this paper. In traditional methods, we have carefully analyzed the computer conversion process from 2D drawing to 3D modeling, and innovatively designed a graphics rendering algorithm aimed at accelerating and optimizing the rendering process. However, despite some progress, traditional technologies still face challenges such as limited interactivity and rendering quality bottlenecks. In view of this, the introduction of virtual reality technology was explored, and a lifelike 3D building environment was successfully constructed by seamlessly integrating real-time rendering engines, high-precision sensors, and advanced interactive devices. This environment not only achieves seamless connection and natural interaction between users and virtual building spaces, but also allows users to freely explore and observe building details in virtual roaming, and deeply interact with virtual elements, greatly enhancing immersive experience and interactive fun. The results indicate that in terms of design efficiency, virtual reality design time is generally shorter than traditional technologies. In terms of visual quality, virtual reality technology scores a perfect 5 points, while traditional technology only scores 4 points. In terms of rendering speed, virtual reality technology is 10[Formula: see text]s faster than traditional technology in residential scenes and 15[Formula: see text]s faster in commercial complex scenes. In terms of data processing capability, when processing 20 sets of data, the average processing speed of virtual reality technology is about 58[Formula: see text]s/GB, while traditional technology is 106[Formula: see text]s/GB. The average error rate of virtual reality technology is 1.0%, while traditional technology is 3.0%. In terms of user experience, the rating for virtual reality technology reached 9.2 out of 10, while traditional technology only scored 6.9. The immersion score for virtual reality technology is 9.3 points, while for traditional technology it is 6.7 points. The interactive depth rating for virtual reality technology is 8.7 points, while for traditional technology it is 6.0 points. In practical applications, the rendering time of virtual reality technology is significantly shorter than traditional rendering technology, and user satisfaction ratings are generally higher, with an average rating of 4.7 points or above (out of 5 points).
