Abstract
A method for scheduling and displaying three-dimensional annotations is provided, relating to the field of realistic three-dimensional visualization technology. The present disclosure covers data services, data scheduling schemes, data storage schemes, annotation avoidance schemes, and annotation efficient display schemes. Users can use this disclosure to schedule and display massive three-dimensional annotations in WebGL at high frame rates while consuming extremely low performance. It solves the problem of text inversion and non-hierarchical zooming of three-dimensional maps in traditional annotation and slicing services which can cause text to appear larger or smaller, breaking through the technical bottleneck that traditional annotation and slicing services that cannot be superposition displayed on 3D models. By using this disclosure, massive annotation data can be displayed without slicing, and rich annotation styles can be customized and displayed by users, providing a more advanced annotation display solution for realistic three-dimensional visualization technology.
