Character texture management method and device

Abstract

Disclosed are a method and device for managing a character texture. The method comprises: determining a texture type corresponding to any character texture to be stored according to a preset correspondence between texture sizes and texture types, and when it is determined that the number of textures stored under the corresponding texture type is smaller than a corresponding upper limit, storing the character texture to be stored under the corresponding texture type, wherein the upper limit of the number of textures under each texture type is configured according to hardware resources of a device, and the more the hardware resources of the device are, the higher the upper limit of the number of textures under a texture type having a correspondingly larger texture size is. In this scheme, the textures can be classified according to the texture sizes and the textures can be stored according to the texture types, and the more the hardware resources of the device are, the higher the upper limit of the number of textures under a texture type having a correspondingly larger texture size is. Therefore, the textures are prevented from being added or deleted too frequently in the current texture management, and thus the storage space of the device can be reasonably utilized.

Description

technical field [0001] The invention relates to the technical field of electronic maps, in particular to a text texture management method and equipment applicable to electronic maps. Background technique [0002] At present, electronic maps often involve the display of text information such as POI (Point Of Interest) names and road names. Before displaying text information, it is usually necessary to render the text involved accordingly, that is, to Each text involved generates a corresponding text texture. [0003] Specifically, since it is a time-consuming operation to generate corresponding text textures from text, therefore, in OPENGL (Open Graphics Library, a professional graphics program interface) or DIRECTX (Direct EXTENSION, referred to as DX, a multimedia programming interface) In engines such as hardware rendering, under normal circumstances, the generated text textures need to be saved accordingly, so that they can be used directly in the next rendering and impr...

AI Technical Summary

Problems solved by technology

[0007] The embodiment of the present invention provides a text texture management method and device, which are used to solve the current problems that the storage space of each device cannot be reasonably used and the rendering efficiency is low due to too many texture additions and deletions when managing text textures.
