摘　　要：文章基于广义四次Bézier样条曲线造型方法,提出一种构造汽车车灯外形的新算法。该算法既可以通过调整控制顶点的位置整体修改车灯外形,也可以通过调整各段曲线形状参数的取值局部改变车灯形状,从而得到造型各异的汽车车灯轮廓。实际应用中利用该算法可结合用户需求,灵活调控轮廓的形状,以满足人们对车灯外形功能化、个性化的审美需求。数值实例表明,该算法切实可行且有效。A new algorithm to construct the shape of the car lamp is proposed based on the generalized quartic Bézier spline curve modeling method. The new algorithm can modify the shape of the car lamp globally by adjusting the position of the control vertex, and can also change the shape of the car lamp locally by adjusting the values of the shape parameters of the curve of each section. In practical application, the shape of contour can be adjusted flexibly to meet the functional and personalized aesthetic needs of people. The numerical examples show that the algorithm is feasible and effective.
