摘要现代社会,随着工作节奏的加快和工作压力的增加,人们愈加需要休闲与娱乐,信息娱乐业也就成为计算机应用的重要发展方向。本课题就是利用计算机动画技术,结合了计算机音乐、图形学和人工智能等学科,以角色的虚拟舞蹈展现音乐形象,涉及到了音乐元素分析识别、角色模型的建立和运动控制等问题。这项工作把科学和艺术相结合,是音乐可视化研究的一个有益的尝试。本文研究了模型基本舞蹈姿态的控制和合成,以及系统对于音乐的表现力等问题,以植物体为虚拟舞蹈角色,最终实现了由用户指定脚本和系统自动生成脚本的两大驱动舞蹈动画,能基本与音乐的节奏、风格、所表达的情感等因素上保持一致,既能模拟一些经典的动作,也可以实现卡通效果。本文的主要工作和贡献包括:1 利用无质量的质点-弹簧模型实现了对系统中模型的交互控制,使姿态设计和脚本编排的工作可视化,并在保持骨架模型形状、从线弹簧到角弹簧的数据转换、关节固定等方面进行了研究。2 运用分层控制的方法完成了群体舞蹈动画模块,实现了队列的连续变换、移位、旋转等,进一步增强了系统对于音乐的表现方式。另外还在双个体模型舞蹈功能中加入了基于弹簧模型的碰撞检测和碰撞反应。3 提出了用马尔可夫链(Markov Chain)的数学模型实现随机脚本动画,并设计了脚本片断库,实现了舞蹈动作片断间的无缝连接,而且舞蹈动画能够符合音乐的风格和节奏,为下一步系统的自动音乐舞蹈动画做了有益尝试。4 把上述三个功能模块融入到系统中,其各控制功能均可以达到实时动画的要求,软件全部是在Qt和OpenGl的开发环境下完成,可以实现系统跨平台运行于Windows和Linux上。
其他摘要In our modern society, people need relaxing and entertainment much morethan before because of the increasing work pace and pressure, so information en-tertainment research is more and more important in computer application ?eld.Here we propose to visulize music with character dancing animation. This projectis based computer animation technique, and relates to the study of computer mu-sic, computer graphics and arti?cial intelligence. There are also many problems toful?ll such a system, including music factors analysis and recognition, construct-ing the character model, and the motion dynamic control. This work, combiningscience and arts, is a signi?cative attempt in the research of music visualization.This thesis focus on the control and blending of the dancing postures, andthe expressive force of our system to music. We choose plants as the character,and ?nally realize a system with two kinds of script-driven dancing animation:speci?ed by user and automatic produced by our system. All the dancing ani-mation can accord with the factors of the selected music including the rhythm,the style, and the feeling. Our system can simulate both the classic movementand the cartoon behavior. The main work and contributions of this thesis includefollowing issues:1 Realize the interactive design of postures for the articulated character byapplying the spring model without mass. We also solve some problems inthis control module including the data conversion from the linear springsto angular springs, keeping the shape of the skeleton model and ?xing theselected joints.2 Complete the group dancing animation module with the hiberarchy controlmethod, which further improve the expressive force of our system. We realizethe pattern transformation of multi-models, and we also ?nish the two-models dancing animation with the collision detection and response basedon spring model.3 Accomplish the stochastic script animation with Homogeneous MarkovChain, which is a preparation for our next work of music-driven dancinganimation. We design the script chips and make the dancing action chipsproduced from the script chips seamlessly connected, and the stochasticdancing animation can also match the style and rhythm of the selected mu-sic.4 Append the three modules to the system, and all the modules can achieve thereal-time animation requirement. What’s more, the software is developedwith Qt and OpenGl, so the system can operate on the operation system ofWindows and Linux.
