中文摘要：
用一条四次带参Bezier曲线统一描述了汽车前脸各造型设计元素的轮廓；提出首先由设计师在平面视图中绘制并编辑汽车前脸造型的二维四次带参Bezierr曲线轮廓图，然后将其投影到车身曲面上，最后通过对曲面的修剪获得汽车前脸造型的方法。该方法基于四次带参Bezier曲线生成与拼接原理，可迅速于全局或局部调整汽车前脸轮廓线条，获得光顺的曲线效果，从而快速获得多种汽车前脸设计的造型方案。
英文摘要：
A method for automobile face design based on Quartic Bezier curves with shape parameters is proposed in this paper, which describes the automobile face contours with one Quartic Bezier curve. Firstly, a Quartic Bezier curve with control points is created and adjusted in a plane; then the curve is projected on the automobile＇s surface; finally, the automobile＇s surface is trimmed and it forms the final shape contours of the automobile face. This meth- od, based on the generation and splicing principle of Quartic Bezier curve, can quickly modify the curve by global or partial adjustment and obtain many design solutions.
