基于超螺旋技术三维头发建模的方法改进

摘要

在虚拟人头发的三维动画建模中,前人所提出的建模方法很难同时兼顾建模速度与模型质量.为了解决建模速度与模型质量之间的矛盾,在超螺旋建模技术的基础上,提出了头发细节类别模型及模型细化.实验中利用超螺旋建模技术,并通过Direct 3D软件建立虚拟人三维头发模型的基础骨骼,然后进行三维头发建模,最后通过时所得到的头发模型细化得到最终的三维头发模型.实验结果显示,利用改进方法所得到的三维头发模型相对于其他建模方法得到的模型更加逼真,基本达到了预期的目的.%The methods suggested by others are difficult to give consideration to the modeling speed and quality in 3D animation modeling of virtual human hair. Based on the super-helical modeling technology, a detailed classification model and model refining of human hair are proposed in this paper to solve the problem mentioned above. On the basis of the super-helical modeling technology, a basic framework of virtual 3D human hair model was built in an experiment with Direct 3D software, and then a 3D hair model was obtained by refining the hair model achieved before. Experimental results show that the 3D hair model obtained by the improved method is more vivid than those obtained by orher methods.
