A simulation method and device for butterfly behaviors in a three-dimensional scene

Abstract

The embodiment of the invention provides a simulation method and device for butterfly behaviors in a three-dimensional scene. The method comprises the steps that based on a Unity 3D platform, butterfly group center nodes and environment influence nodes are created in a three-dimensional scene, first scripts used for simulating butterfly group behaviors are hooked under the butterfly group center nodes, and second scripts used for simulating butterfly individual behaviors are hooked under the environment influence nodes; a plurality of butterfly individual nodes are created, the plurality of butterfly individual nodes are hung under the butterfly group center node to serve as sub-objects, and initial positions of the butterfly individual nodes are set randomly; and in each frame rendering,individual behaviors of butterfly individual nodes falling into a bounding box of the environment influence node are updated according to the second script, and group behaviors of other butterfly individual nodes except the bounding box are updated according to the first script.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of three-dimensional modeling, and more specifically, relate to a method and device for simulating butterfly behavior in a three-dimensional scene. Background technique [0002] Butterfly is a beautiful insect loved by people from all over the world. In film and television, animation, virtual display and interactive games, butterflies often appear as beautiful and romantic elements or gorgeous special effects, especially when a large group of butterflies suddenly pass from the virtual object or the protagonist of the film. When it appears and flies around, it can give people a magical and wonderful feeling. Unity3D is a multi-platform comprehensive development tool developed by UnityTechnologies. Using Unity3D to support animation editing system and particle system can quickly develop 3D animation scenes. [0003] At present, the most common computer simulation methods of butterfly beh...

Problems solved by technology

Moreover, this method is not universal. Every time the simulated object or scene is replaced, the flight trajectory and behavior animation of the butterfly must be redesigned, which requires a lot of working time for the artist and can easily cause wrong animation settings.

[0005] The second type of method uses a random particle system for simulation, which is better in applicability, but due to the completely random characteristics of particle simulation, after setting the properties of the particle emitter, it is impossible to individually control and control the properties of individual particles. Therefore, it cannot simulate the resting, foraging, and escape behaviors of individual butterflies very well, and it is difficult to simulate the interactive behavior between butterfly objects and other virtual objects in 3D scenes
