Vegetation scene rendering method

Abstract

The invention discloses a vegetation scene rendering method. The vegetation scene rendering method comprises steps that for each facet of a to-be-rendered object in a vegetation scene, vertex offset is carried out according to a principle that a vertical distance to a bottom portion of the facet is in direct proportion to offset amount of vertexes, and an offset direction is perpendicular to a plane of the facet; the facet after offset is utilized to render the to-be-rendered object. The method is advantaged in that a facet sense problem during scene rendering can be avoided, and rendering trueness is improved.

Description

technical field [0001] The invention relates to a three-dimensional scene rendering technology, in particular to a vegetation scene rendering method. Background technique [0002] Rich vegetation can effectively enhance the realism of the scene. The procedural vegetation generation technology can use less storage space and use the powerful computing power of the CPU to generate grass meshes at runtime, and is widely used in graphics engines. [0003] In vegetation scenes, the generated vegetation is usually quite dense. In the traditional procedural vegetation generation scheme, a star grid formed by the intersection of three square patches is used (the angle between the patches is 60 degrees). , to simulate the appearance of vegetation clusters, such as figure 1 shown. When rendering, the texture of vegetation (such as grass) will be pasted on each patch. [0004] In the above vegetation scene rendering scheme, when the direction of the camera is close to parallel to th...

Problems solved by technology

[0005] It can be seen that using the existing vegetation scene rendering method, the camera will have a patchy problem when observing the vegetation from certain angles
