The application of fractal design models provides a new perspective and infinite possibilities for artistic pattern creation, which is of great significance for promoting the progress of art and design. However, traditional fractal design models still suffer from slow pattern generation speed and low user satisfaction. This article aimed to use virtual reality technology to construct the latest art pattern fractal design model, in order to better meet the actual needs of current users. In the article, virtual reality was first used to model the art space, and then fractal was constructed through iterative functions; furthermore, the use of local iterative functions made image fractal compression more convenient; afterwards, the image stitching algorithm was applied to complete the stitching of panoramic images of artistic patterns in fractal design models; finally, a real-time interactive design tool was developed and the user experience was optimized. In order to test the effectiveness of the fractal design model for art patterns based on virtual reality technology, this paper compared it with traditional models. Through experiments, it was found that when the generated artistic pattern was 100, the model in this article only took 104.6 s, while the traditional model took 224.3 s. At the same time, the user satisfaction of the model in this article was much higher than that of traditional models. Through experiments, the effectiveness of the fractal design model in terms of production speed and user satisfaction was verified. Through the study of this its conducted, a new graphic design modeling method was proposed to promote the progress of art and design.
