Accompanied by the rapid development of science and technology, the application of digital VR technology in kindergarten and preschool education has gradually become a hot spot of educational innovation. In this paper, with the help of digital VR technology, we build an intelligent learning platform full of exciting and exploratory features to provide kindergarten children with a more vivid and intuitive learning experience. The smart learning platform for preschool education consists of the management module, teaching resource base module, collaborative learning module, and intelligent evaluation module. Virtual reality technology is utilized on the platform to create a virtual teaching module that enhances the teaching method. Then the construction of the virtual classroom three-dimensional model is enhanced and improved. A geometric curvature high-fidelity three-dimensional model accelerated drawing method is proposed. The triangle folding algorithm is improved based on the improved quadratic error metric to enhance the quality of the three-dimensional drawing of the virtual classroom. Through the application of virtual teaching in teaching experiments, it has been found that it has significantly improved children’s cognitive ability and creativity. The percentage of parents’ satisfaction with the teaching effect of the smart learning platform reached 74.2%, indicating that parents are more likely to recognize the kindergarten’s application of the smart learning platform.
