Map plotting method and device, computing equipment and storage medium

Abstract

The invention provides a map plotting method and device, computing equipment and a storage medium. The map plotting method comprises the following steps: acquiring multiple levels of detail of a target terrain patch in a map to be plotted; determining map scene data of the multiple levels of data of the target terrain patch, wherein the map scene data comprise color data, normal data and materialinformation data; performing baking rendering o the multiple levels of detail of the target terrain patch, and storing generated baking information; receiving a map plotting instruction, acquiring thebaking information corresponding to the multiple levels of detail of the baked target terrain patch, and plotting the map to be plotted according to the baking information. According to the map plotting method, the map to be plotted is partitioned according to a distance from a virtual camera, and the levels of detail obtained by the partitioning are baked to generate the corresponding baking information; when the map needs to be plotted, the baking information can be directly loaded to a corresponding position to realize the map plotting.

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.
