Abstract

The invention provides a three-dimensional model loading method. The method comprises the steps of loading triangular patch data and first triangular patch data of connection surface data of a three-dimensional model to form a part of the three-dimensional model, wherein the first triangular patch data is triangular patch data capable of reflecting the outline of the three-dimensional model, and the area of each triangular patch is greater than a second threshold T2; and after the first triangular patch data is loaded, requesting for sending second triangular patch data to a remote server through a browsing client, and in response to the request, sending the second triangular patch data to the browsing client by the remote server, wherein the second triangular patch data is triangular patch data capable of reflecting the details of the three-dimensional model, and the area of each triangular patch is smaller than or equal to the second threshold T2.

Description

technical field [0001] The present invention relates to a processing method and device for a three-dimensional model, in particular to a method for three-dimensional interaction, a method for rapidly retrieving a three-dimensional model, a method for loading a three-dimensional model and a method for rapidly rendering a three-dimensional scene. Background technique [0002] In recent years, with the development of computer and communication technology, the ability of computing devices, that is, the communication efficiency between computing devices, has been greatly improved, prompting the information processing of power grids and power systems to transform from two-dimensional information to three-dimensional information, and in multiple Aspects form technical exploration, experimentation and breakthroughs. [0003] In terms of three-dimensional information acquisition, CN205375587 provides a "3D model reconstruction device for simulation", CN105760568 provides a "device an...
