A Dynamic Model Loading Method Based on 3D Coordinate Interchange

Abstract

The invention relates to a dynamic model loading method based on three-dimensional coordinate interchange. The method comprises the following steps: (1) obtaining coordinate data of a planar axis line and a longitudinal axis line of engineering according to engineering design data, and storing the coordinate data into a database; (2) making three-dimensional models according to the engineering design data, and grouping the three-dimensional models according to a construction process; (3) creating data of a corresponding relationship between each three-dimensional model and mileage, and storing the data into the database; (4) setting a model loading region; and (5) converting a current visual field coordinate into a corresponding model for dynamic loading by a backend server. Compared with the prior art, the method can be across multiple platforms, is high in three-dimensional coordinate interchange mileage precision and wide in technical application range, can be used in the technical fields of three-dimensional platform positioning, data hooking, achievement displaying and the like, and has the advantages that the model loading speed is high, and the broadband burden can be reduced.

Description

technical field [0001] The invention relates to a virtual reality technology, in particular to a model dynamic loading method based on three-dimensional coordinate exchange. 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. In the construction of highways and bridges, virtual reality technology has also been applied. Because roads and bridges need to process a large amount of 3D models and texture data at the same time, this situation requires high co...

Problems solved by technology

Most of the virtual reality projects now rely on the PC client. When using the product, you must download and install it first. In the case of a poor network, the waiting time of the user is greatly increased, which is not good for the user. Experience is not a good product for enterprises

To give users a good visual experience in virtual reality, a large number of fine model support is required. The large size and large number of models will lead to problems such as slow network loading and data interaction delay.
