Grass model processing method and device, electronic equipment and readable medium

Abstract

Embodiments of the invention provide a grass model processing method and apparatus, an electronic device and a readable medium. The method comprises the steps of determining a normal vector of each vertex in a to-be-rendered grass model; controlling the normal vector to deviate towards a first direction, wherein the first direction is a direction opposite to the gravity direction; based on the deviated normal vector, an acting force vector is determined, and the acting force vector is used for simulating gravity; according to the acting force vector and the current position of each vertex of the grass model, determining a to-be-shifted target position of each vertex of the grass model; and controlling each vertex of the grassland model to move to the corresponding target position to obtain the grassland under the gravity influence. And rapid adjustment of the grass model is realized, so that the grass model can naturally show a droop effect. In addition, the grass model is easy to adjust subsequently, and the mixing effect of the gravity effect and other effects is easy to show.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional models, in particular to a processing method of a grass model, a processing device of a grass model, an electronic device and a computer-readable medium. Background technique [0002] In the game, in order to display the 3D scene with rich details, you can add a grass model to the 3D scene. At the same time, in order to make the 3D scene more natural, it is usually necessary to show the effect of the grass model drooping naturally under the influence of gravity. [0003] Generally speaking, to show the effect of the grass model drooping naturally under the influence of gravity, you can set a number of intersecting insert models, and then set the textures of the naturally drooping grass on the insert models, so as to realize the natural drooping effect of the grass Effect. However, if the grass model set by this method needs to add other display effects to the grass model later,...
