Abstract

The present application provides a dynamic display apparatus and method for a three-dimensional dynamic plotted-point label. The apparatus comprises: a point label display mode setting module, which is used for setting a display model and a corresponding attribute of a three-dimensional dynamic point label; a dynamic point label display module, which is used for scheduling, according to the display model and the corresponding attribute of the point label, a label resource management module to read corresponding graphic information and performing a graphic display in a three-dimensional scene; and a point label resource management module, which is used for reading the corresponding graphic information according to an identifier comprised by the attribute of the point label. According to dynamic display apparatus and method for a three-dimensional dynamic plotted-point label provided by the present application, by setting a three-dimensional dynamic plotted-point label object with multiple display mode attributes, multiple display modes of a same object can be implemented for a user, thereby effectively reducing the complexity of a display application of the three-dimensional dynamic label.

Description

technical field [0001] The present application relates to the technical field of dynamic plot point display of Geographic Information System (GIS, Geography Information System), in particular, to a dynamic display device and method for three-dimensional dynamic plot point labels. Background technique [0002] With the continuous deepening and expansion of 3D GIS applications, users' demand for 3D dynamic plotting functions is becoming stronger and stronger. The dynamic plotting function in the 3D geographic information system has different requirements from the 2D geographic information system. For the point label, the user needs to display the same point label in different ways in different scenarios. For example, sometimes it is necessary to display the point label Displayed in bulletin board mode, sometimes it is necessary to display the point label as a fixed and directional vector, and sometimes it is necessary to display the point label as a more vivid model, and when ...
