Terrain tile data rendering method and device, electronic equipment and storage medium

Abstract

The invention relates to a terrain tile data rendering method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a rendering request for a to-be-rendered terrain tile, and obtaining tile data corresponding to a tile identifier according to the tile identifier, the tile data comprising position data and image data; taking the image data corresponding to the tile identifier as texture data of a pre-created three-dimensional target texture; and rendering the texture data through the three-dimensional target texture according to the position data corresponding to the tile identifier and the first corresponding relationship. According to the method provided by the invention, the image data corresponding to the tile identifier can be taken as the texture data of the three-dimensional target texture, and the position data of the terrain tiles are associated with the texture coordinates of the three-dimensional target texture, so that the rendering of a plurality of terrain tiles can be realized through one three-dimensional target texture, and when different terrain tiles are rendered, the rendering efficiency is improved. And texture objects do not need to be switched, so that the rendering fluency is ensured, and the rendering efficiency and the performance of the GPU can be improved.

Description

technical field [0001] The present invention relates to the technical field of geographic information, in particular, the present invention relates to a rendering method, device, electronic equipment and storage medium of terrain tile data. Background technique [0002] In recent years, 3D data visualization technology has become more and more mature. This technology is favored by research institutions at home and abroad for its strong controllability, high safety, low cost, and intuitive and rich display information. However, limited by many factors such as software and hardware conditions, the current real-time 3D display platform is difficult to meet the requirements of practical applications, and the current research on related technologies is insufficient. Therefore, at present, the independent and controllable 3D display platform realized by using the underlying graphics rendering technology and related algorithms is still the mainstream solution. Depending on the impl...
