Modeling Research On Scenes And Roles In Crowd Evacuation Simulation

With the continuous development of computer science and technology,three-dimensional animation in film and television advertising,role animation,film effects,games,TV column packaging and other fields play an increasingly important role,making new challenges in modeling modeling and character roles in crowd evacuation simulations.This paper mainly through the modeling of three-dimensional scenes and characters to achieve the crowd evacuation simulation animation generation,mainly including the following aspects:1.For creating a 3D building modelThe modeling of traditional buildings is done in the Maya software at the discretion of the creator,rather than based on real proportions,which is far less than the requirements of modern simulation technology.Therefore,this article is mainly using the three-dimensional animation software Maya and Maya comes with the Mel language based on the real proportion of the three-dimensional building model to create,and then according to the different needs of the building to give a different texture map,And finally get a realistic and colorful three-dimensional building model.2.Research on the Method of Character Modeling.According to the different characteristics of the characters to shape the characters,the main method is to use the introduction of the character model of the front and side view for the reference map,combined with a special copy of the basic modeling method.And the character models show UV,save the UV snapshot,using Photoshop for texture simplified character model,and the texture of the map to the character model,and ultimately generate a variety of character models.and ultimately generate all kinds various character models.And then add bones to the character model and draw the skin weight.And finally use Motion builder for character action binding,the establishment of the character model library;generate a variety of character models.3.The generation of evacuation simulation animationThe entire character model and the three-dimensional building model are introduced into the crowd simulation platform and plan the path for the character model.By switching the camera's orientation,the animation of the evacuation simulation in the 3D scene is realized on the real-time simulation platform.
