Abstract

The invention discloses a three-dimensional model data dynamic loading method, and relates to the technical field of virtual reality, and the method comprises the following steps: pre-starting a program, loading preset information, activating a target part, and calling corresponding matching information of the target part; extracting outer boundary information of the target component, wherein a maximum inscribed rectangle of a projection circle of the bounding ball on the ground serves as an approximate outer boundary of the target component; judging the inclusion relation between the target component and the outer boundary of the three-dimensional model, and selectively loading the target component in the region of the three-dimensional model. According to the method, the optimization of three-dimensional model data loading is realized, the bandwidth load is reduced, the response speed is high, the number of loading items is obviously reduced, the data redundancy is effectively reduced, the loading efficiency is improved, the operating cost is reduced while the working efficiency is improved, the problems of slow three-dimensional model network loading and data interaction delay are solved, and the fluency of user experience interaction is improved.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a method for dynamically loading three-dimensional model data. Background technique [0002] Virtual reality is a high-tech that has emerged in recent years. Virtual reality is a three-dimensional virtual reality generated by computer simulation, providing users with simulations of vision, hearing, touch and other senses, allowing users to experience real-time, Observe things in three-dimensional space without limitation. Urban planning has always been one of the most urgent areas for new visualization technology. Virtual reality technology can be widely used in all aspects of urban planning and bring tangible and considerable benefits. However, with the development of computer software and hardware technology in recent years Improvement, some original technical bottlenecks have been solved, so that the application of virtual reality has reached an unprecedented developm...
