Abstract

The application discloses a vegetation distribution simulation method and apparatus. The method comprises: extracting the distribution feature of a vegetation sample; obtaining a plurality of first distribution units according to the distribution feature; subjecting the first distribution units to boundary processing to obtain a plurality of second distribution units; and splicing the plurality of second distribution units to obtain a vegetation distribution simulation result. The vegetation distribution simulation method and apparatus achieve a rapid simulation of vegetation distribution with any vegetation characteristic.

Description

technical field [0001] This application belongs to the field of computer graphics, in particular, it relates to a vegetation distribution simulation method and device. Background technique [0002] In computer graphics, the simulation of natural scenes is an important topic, and the distribution simulation of vegetation is an important part that affects the realism of the scene. The simulation of vegetation distribution has two main functions. One is the scene simulation for forestry research. For example, in order to facilitate the intuitive analysis of forestry information or related ecological data, the virtual scene simulation of the forest is carried out, that is, the real forest. Carry out three-dimensional reconstruction, and form a sample block by generating the position distribution information of plants in the forest area, and further construct a large-scale forest scene. The vegetation distribution simulation can also have other usage scenarios, for example, the ...
