One simple tip for modeling the wood slates was to tessellate the faces and then add a small noise on the vertex so we can get a nice random surface that gives some realistic look of old wood.
再创建木板有一条小建议：在表面附上纹理并在顶点加一些噪点，这样表面更随机看起来像真实的老木头。

Interpolation to vertex positions and normals is one of important contents in parametric surface modeling.
顶点位置和法向插值是参数曲面造型的重要内容。

But surface generation requests through a series of curves, and it finally produces control vertex and node vector satisfied with surface request.
