Application of Graph Neural Network and Virtual Reality Based on the Concept of Sustainable Design

With the rapid development of science and technology, sustainable design has gradually become the core concept in the field of design. The purpose of this study is to explore the application of a graphical neural network (GNN) model combined with CAD in order to support the practice of sustainable design. By integrating the latest research progress at home and abroad, we show the innovative potential of the combination of CAD and VR in the design field. At the technical and methodological level, we propose a new model based on a graph neural network, which integrates CAD design data with VR experience data to achieve real-time and immersive feedback and interaction of designers. The experimental design selects the actual design case and compares the traditional design process with the design process based on the GNN model. The results show that the model has significantly improved the design efficiency and quality, which helps designers better understand the feasibility of the design scheme. The research provides new ideas and tools for the integration of sustainable design concepts and technology in the design field and further promotes the development of the design industry. © 2024 U-turn Press LLC.
