复杂头发三维建模方法研究与仿真

Complex 3d Modeling Hair Method Research and Simulation

研究头发的真实建模问题。针对三维头发建模过程中,当头发浓密、杂乱、重叠度高、清晰度不高,建模中会造成三维特征坐标的混淆与重叠,仿真建模头发的真实感不强。为了解决上述问题,提出了头发粒子束建模方法,将头发的建模看成是有一定方向的粒子,通过方向预判、实体填充等步骤,完成真实感三维建模。试验结果表明,方法能够区分杂乱的头发轮廓,可以很好地完成复杂头型背景下的头发三维仿真,最终改进了三维头发模型的真实感和清晰度,达到了令人满意的效果。

Researching hair modeling problem. In 3d simulation process, when hair is thick, tousling and overlapping, confusion and overlap can be caused in the modeling of the three-dimensional features coordinates, articulation of simulation hair modeling is not high. A modeling method is put forward based on hair particle beam, and this hair modeling is considerd as particles with a certain direction. Through the steps of direction anticipation and entity filling, realistic modeling is finished. Experimental results showed that the method can distinguish messy hair outline, improve the reality and articulation of 3d hair model, and achieve satisfactory results.
