摘要

NURBS可以通过指定一些控制点及其权重来创建自由形式的外壳。然而，即使增加了权重，也很难创建严格通过所有指定控制点的表单。本文提出了一种利用傅里叶变换的自由形式壳屋顶的初始形态发生技术。该技术可以创建严格通过所有指定控制点的表单。讨论了该技术与NURBS的比较，并给出了三个实例。

An Initial-Morphogenesis Technique of Free-Form Shell Roofing Based on a Fourier Transform

NURBS can create free-form shells by specifying a number of control points and their weights. However, it is challenging to create a form that strictly passes through all the specified control points even with increased weights. This paper proposes an initial-morphogenesis technique of free-form shell roofing using a Fourier Transform. The technique can create forms that strictly pass through all the specified control points. The comparison between the proposed technique and NURBS is discussed and three examples are demonstrated.
