【摘要】：计算机动画是计算机图形学和应用数学以及美术相结合的产物,是伴随着计算机硬件和图形算法高速发展起来的一门高新技术,它综合利用了计算机图形学、艺术、应用数学、物理学以及其它相关学科的知识,在计算机上显示逼真的虚拟画面。在计算机图形学中,人体动画是具有挑战性的课题之一。它具有广泛的应用范围,在影视创作、网络游戏、广告设计、虚拟现实等诸多领域有着重要的用途。人体仿真可使人类在很多状态下预先知道过程中的细节,进而可以制造出机器人做出人类的“不可能完成之任务”。而且人体运动也是很复杂的,这方面需要做的工作很多。可变形三维模型的仿真是基于当前医学影像以及康复机器人的现实需求下,在计算机上实现对人体肢体的运动控制仿真以及肌肉皮肤变形仿真。该研究的重点是在计算机上实现可变形三维模型的仿真。研究分析肢体运动控制技术,提出了基于几何的人体动画控制方法。基于OpenGL技术利用VC++ 6.0开发工具进行开发,首先建立了人体手指几何模型,该模型包括手指的关节与三段手指部分,它们分别由点的绘制构成。然后推导了用于手指运动控制的重要参数的计算公式。在模型的架构中,通过参数的选取,实现对实时动画的控制。
[Abstract]:Computer animation is the product of the combination of computer graphics, applied mathematics and fine arts. It is a high and new technology with the rapid development of computer hardware and graphics algorithms. It makes comprehensive use of computer graphics, art and applied mathematics. Knowledge of physics and other related disciplines, showing realistic virtual images on a computer. In computer graphics, human animation is one of the challenging topics. It has a wide range of applications in film and television, online games, advertising design, Virtual reality and many other areas have important applications. Human simulation allows humans to know the details of the process in advance in many states. In turn, robots can be made to do "impossible tasks" for humans. And human motion is also very complex, and there is a lot of work to be done in this area. The simulation of deformable 3D model is based on the current medical image and the actual needs of rehabilitation robot. The motion control simulation and muscle skin deformation simulation of human limbs are realized on the computer, and the emphasis of this research is to realize the simulation of deformable 3D model on the computer. Based on the research and analysis of limb motion control technology, the method of human animation control based on geometry is put forward. Firstly, the geometric model of human finger is established based on the development tool of VC 6.0 based on OpenGL technology. The model consists of the joint of the finger and the three-segment finger, which are respectively composed of the point drawing. Then, the calculation formula of the important parameters used for the finger motion control is derived. In the framework of the model, the parameters are selected. Realize the control of real-time animation.
