Rendering method and device for virtual grass in game and electronic equipment

Abstract

The invention provides a rendering method for a virtual grass cluster in a game. The method comprises the following steps: determining stress points of grass leaves of the virtual grass cluster in a current game scene; when at least one game skill is rendered in the current game scene, determining force field information of the game skill; generating a scene force field graph matched with the current scene according to a preset four-channel color buffer and the force field information of at least one skill; and rendering the virtual grass according to the scene force field graph and the stresspoints. Therefore, a multi-skill coverage rendering effect is achieved, a vivid grass cluster effect is rendered, grass clusters are prevented from deforming in the rendering process, and the image processing efficiency and the user experience are improved.

Description

technical field [0001] The invention relates to the neighborhood of animation interaction processing, in particular to a rendering method, device and electronic equipment for virtual grass in a game. Background technique [0002] The grass used for stealth in the game, the animation of its model is usually done through skeletal animation or vertex animation, and the animation of the grass is usually realized through the vertex animation of the shader. [0003] In order to realize the interaction between skills and grass in vertex animation, there are two general methods. The first one is to directly transmit the required force data of grass to the vertex shader of the grass model, and then the shader itself operates through the received data. The force and current position of each vertex of each grass model. However, this method cannot meet the needs of multiple different force fields, such as figure 1 The above is a schematic diagram of the rendering effect of a virtual g...

AI Technical Summary

Problems solved by technology

However, this method cannot realize the synthesis of multiple forces.

At the same time, if the rendering is done through the vertex shader, each vertex considered is independent, which will cause the shape of the grass leaves to change in some cases
