A map drawing method, device, computing device and storage medium

Abstract

This specification provides a map drawing method, device, computing device and storage medium, wherein the map drawing method includes: obtaining the multi-level of detail of the target terrain block in the map to be drawn; determining the multi-level of detail map scene of the target terrain block data, the map scene data includes color data, normal line data and material information data; based on the map scene data, bake and render the multi-level of detail of the target terrain block, and store the generated baking information; receive the map The drawing instruction acquires the baking information corresponding to the multi-level of detail of the target terrain block that has been baked, and draws the map to be drawn based on the baking information. In the present invention, the map to be drawn is divided into blocks according to the distance from the virtual camera, and the level of detail after the block is baked to generate corresponding baking information. When the map needs to be drawn, the baking information can be directly loaded to the corresponding position for map drawing.

Description

technical field [0001] This specification relates to the field of Internet technologies, and in particular to a map drawing method, device, computing device and storage medium. Background technique [0002] The method of large-scale map drawing has always been a research hotspot in the field of computer graphics. The drawing of large-scale map scenes has a very wide range of applications in the fields of animation production, film and game production. [0003] Although the development of display hardware has been very rapid in recent years, however, due to the increasing magnitude of model data involved in large-scale map scene drawing, and with the development of technology, the rendering requirements have become higher, resulting in a large number of materials and larger textures. The number of textures increases, and the materials involved in map drawing are very complex, and the number of shader instructions that need to be used often reaches the order of four digits, wh...

[0003] Although the development of display hardware has been very rapid in recent years, however, due to the increasing magnitude of model data involved in large-scale map scene drawing, and with the development of technology, the rendering requirements have become higher, resulting in a large number of materials and larger textures. The number of textures increases. When drawing maps, the materials involved are very complex, and the number of shader instructions that need to be used often reaches the order of four digits, which leads to excessive hardware performance during real-time drawing.
