【摘要】： 當(dāng)前計(jì)算機(jī)技術(shù)迅速發(fā)展,計(jì)算機(jī)創(chuàng)造的虛擬人在電影、游戲、廣告等領(lǐng)域都有著極其廣泛的應(yīng)用。作為虛擬人研究的一個(gè)部分,頭發(fā)的仿真和動(dòng)態(tài)實(shí)現(xiàn)十分復(fù)雜,幾乎涉及了計(jì)算機(jī)圖形學(xué)技術(shù)的各個(gè)方面,具有非常重要的理論價(jià)值。如何實(shí)現(xiàn)頭發(fā)的繪制以及如何進(jìn)行頭發(fā)造型和動(dòng)態(tài)模擬一直是計(jì)算機(jī)圖形學(xué)領(lǐng)域的一個(gè)非常具有挑戰(zhàn)性的問題。 本文主要內(nèi)容包括頭發(fā)建模、發(fā)型設(shè)計(jì)、頭發(fā)的動(dòng)態(tài)模擬等,設(shè)計(jì)了一個(gè)可支持多種發(fā)型的框架,實(shí)現(xiàn)了一種實(shí)時(shí)性強(qiáng)仿真度高的頭發(fā)動(dòng)態(tài)模擬算法,并且能夠在圖形硬件的支持下獲得更快的速度。在頭發(fā)建模方面,采用了發(fā)線模型來表示頭發(fā),把頭發(fā)視為馬爾可夫鏈。在發(fā)型設(shè)計(jì)方面,使用了點(diǎn)約束、軌跡約束、方向約束三種約束方法對頭發(fā)進(jìn)行造型,模型的結(jié)構(gòu)簡單,能夠支持多種發(fā)型。在頭發(fā)的動(dòng)態(tài)模擬方面,使用了Byoungwon Choe的彈簧頭發(fā)絲模型,在原來的頭發(fā)絲模型基礎(chǔ)上,添加了線性彈簧和角度彈簧,這是一種基于物理的動(dòng)態(tài)模擬技術(shù)。 本文算法簡潔,效率高,可以實(shí)現(xiàn)多種發(fā)型的高質(zhì)量實(shí)時(shí)繪制以及發(fā)型的動(dòng)態(tài)模擬。算法實(shí)現(xiàn)時(shí),使用了OpenGL、wildMagic4席和0sg為作為開發(fā)工具,具有較好的可移植性,經(jīng)實(shí)驗(yàn)表明,能在普通的硬件配置上,實(shí)現(xiàn)高質(zhì)量的發(fā)型設(shè)計(jì)和動(dòng)態(tài)模擬。
[Abstract]:With the rapid development of computer technology, virtual human created by computer has been widely used in film, game, advertisement and so on. As a part of the research of virtual human, the simulation and dynamic realization of hair is very complicated, which almost involves all aspects of computer graphics technology, and has very important theoretical value. How to realize the drawing of hair and how to model and simulate the hair dynamically has been a very challenging problem in the field of computer graphics. The main contents of this paper include hair modeling, hairstyle design, hair dynamic simulation and so on. And can get faster speed with the support of graphics hardware. In the aspect of hair modeling, the hair line model is used to represent the hair, and the hair is regarded as a Markov chain. In hairstyle design, three constraint methods, point constraint, locus constraint and direction constraint, are used to shape hair. The model is simple in structure and can support multiple hairstyles. In the aspect of dynamic simulation of hair, Byoungwon Choe's spring hair model is used. Linear spring and angle spring are added on the basis of the original hair model, which is a kind of dynamic simulation technology based on physics. The algorithm is simple and efficient. It can realize high quality real-time rendering of multiple hairstyles and dynamic simulation of hairstyles. When the algorithm is implemented, OpenGL,wildMagic4 and 0sg are used as development tools, which has good portability. Experiments show that it can achieve high quality hairstyle design and dynamic simulation in common hardware configuration.
