【摘要】：随着计算机科学技术的不断发展,三维动画在影视广告、角色动画、电影特效、游戏、电视栏目包装等各个领域中发挥了越来越重要的作用,使得在人群疏散仿真中对三维建筑建模与人物角色的建模提出了新的挑战。本文主要是通过对三维场景和人物角色的建模研究来实现人群疏散仿真动画的生成,主要包括以下几个方面:1.对于创建三维建筑模型的方法。传统建筑物的建模是在Maya软件中按照创建者的意愿进行随意的创建,而不是基于真实比例进行创建,这种创建方法远远达不到现代仿真技术的要求。因此本文主要是使用三维动画软件Maya和Maya自带的Mel语言进行基于真实比例的创建出三维建筑模型,再根据建筑物的不同需求赋予不同的材质贴图,最终获得具有真实感并且丰富多彩的三维建筑模型。2.对于人物角色建模方法研究。根据人物形体的不同特征进行人物建模,主要使用的方法是导入人物模型的前视图和侧视图为参考图,结合特殊复制的方法进行基础建模。并对人物模型展UV,保存UV快照,使用图像处理软件Photoshop对人物模型进行纹理简化处理,并将经过处理的贴图赋予人物模型,最终生成各式各样的人物模型。再对人物模型添加骨骼并绘制蒙皮权重,最后使用Motionbuilder进行人物动作的绑定,建立人物模型库,生成具有多样性的人物模型。3.人群疏散仿真动画的生成。将生成的所有人物角色模型和三维建筑模型导入人群运动仿真平台,并为人物模型规划路径,通过切换摄像机的方位,在实时仿真平台上实现在三维场景中人物疏散仿真的动画。
[Abstract]:With the development of computer science and technology, 3D animation plays a more and more important role in the fields of film and television advertising, character animation, film special effects, games, TV column packaging, etc. In this paper, the animation of crowd evacuation simulation is generated through the research of 3D scene and persona modeling, which is a new challenge to 3D building modeling and persona modeling in crowd evacuation simulation. It mainly includes the following several aspects: 1.The method of creating 3D building model. Traditional building modeling is created at will in Maya software, not on the basis of real scale. This method can not meet the requirements of modern simulation technology. Therefore, this paper mainly uses 3D animation software Maya and Mel language brought by Maya to create 3D architectural model based on real scale. Then according to the different needs of the building to give different materials map, and finally get a realistic and colorful three-dimensional architectural model. 2. For the study of persona modeling method. According to the different characteristics of the character, the character modeling, The main method is to import the front view of the persona model and the side-view graph as the reference diagram, combine the special copy method to carry on the basic modeling, and expand the UV of the persona model, save the UV snapshot, The image processing software Photoshop is used to simplify the texture of the character model, and the processed map is assigned to the character model, and finally various kinds of character models are generated. Then, the skeleton is added to the character model and the weight of the skin is drawn. Finally, we use Motionbuilder to bind the character action and establish the character model library. Generate a diverse character model .3.The generation of crowd evacuation simulation animation. All the generated personas and three-dimensional building models will be imported into the crowd movement simulation platform, and for the human model path planning, by switching the location of the camera, The animation of evacuation simulation in three-dimensional scene is realized on the real-time simulation platform.
