【摘要】：計(jì)算機(jī)動(dòng)畫(huà)是計(jì)算機(jī)圖形學(xué)和應(yīng)用數(shù)學(xué)以及美術(shù)相結(jié)合的產(chǎn)物,是伴隨著計(jì)算機(jī)硬件和圖形算法高速發(fā)展起來(lái)的一門(mén)高新技術(shù),它綜合利用了計(jì)算機(jī)圖形學(xué)、藝術(shù)、應(yīng)用數(shù)學(xué)、物理學(xué)以及其它相關(guān)學(xué)科的知識(shí),在計(jì)算機(jī)上顯示逼真的虛擬畫(huà)面。 在計(jì)算機(jī)圖形學(xué)中,人體動(dòng)畫(huà)是具有挑戰(zhàn)性的課題之一。它具有廣泛的應(yīng)用范圍,在影視創(chuàng)作、網(wǎng)絡(luò)游戲、廣告設(shè)計(jì)、虛擬現(xiàn)實(shí)等諸多領(lǐng)域有著重要的用途。人體仿真可使人類(lèi)在很多狀態(tài)下預(yù)先知道過(guò)程中的細(xì)節(jié),進(jìn)而可以制造出機(jī)器人做出人類(lèi)的“不可能完成之任務(wù)”。而且人體運(yùn)動(dòng)也是很復(fù)雜的,這方面需要做的工作很多。 可變形三維模型的仿真是基于當(dāng)前醫(yī)學(xué)影像以及康復(fù)機(jī)器人的現(xiàn)實(shí)需求下,在計(jì)算機(jī)上實(shí)現(xiàn)對(duì)人體肢體的運(yùn)動(dòng)控制仿真以及肌肉皮膚變形仿真。該研究的重點(diǎn)是在計(jì)算機(jī)上實(shí)現(xiàn)可變形三維模型的仿真。 研究分析肢體運(yùn)動(dòng)控制技術(shù),提出了基于幾何的人體動(dòng)畫(huà)控制方法�；贠penGL技術(shù)利用VC++ 6.0開(kāi)發(fā)工具進(jìn)行開(kāi)發(fā),首先建立了人體手指幾何模型,該模型包括手指的關(guān)節(jié)與三段手指部分,它們分別由點(diǎn)的繪制構(gòu)成。然后推導(dǎo)了用于手指運(yùn)動(dòng)控制的重要參數(shù)的計(jì)算公式。在模型的架構(gòu)中,通過(guò)參數(shù)的選取,實(shí)現(xiàn)對(duì)實(shí)時(shí)動(dòng)畫(huà)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.
