Problems solved by technology

[0004] Since the terrain contained in the map image is relatively flat in some cases, and complex in some cases, if the distance between the flat terrain and the camera is relatively close, more rendering resources will be allocated for rendering, but not Can improve the fineness of this image, so it will lead to a waste of rendering resources

Abstract

The embodiment of the invention provides a map rendering method and device, equipment and a storage medium. The method comprises the steps: acquiring height values corresponding to multiple terrain vertexes contained in a map image; determining terrain change complexity corresponding to the map image based on the height values corresponding to the terrain vertexes; determining a distance between the map image and the camera; determining a rendering resource allocation amount corresponding to the map image based on the terrain change complexity and the distance; and rendering the map image based on the rendering resource allocation amount. By adopting the method and the device, the distribution amount of the rendering resources can be considered according to the actual situation of terrainchange complexity, so that the rendering resources can be saved as much as possible while the rendering effect is ensured.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a map rendering method, device, equipment and storage medium. Background technique [0002] Since a large amount of calculation is involved in the process of rendering a map image, it is proposed in the related art to render the map image by using a multi-level of detail (Levels of Detail, LOD) technology. [0003] In LOD technology, you can first determine the distance between the map image to be rendered and the preset camera, and allocate more rendering resources to those map images that are closer to the camera to complete the rendering process, and for those that are farther from the camera Map images that are farther away will allocate less rendering resources for rendering. [0004] Since the terrain contained in the map image is relatively flat in some cases, and complex in some cases, if the distance between the flat terrain and the camera is relatively...
