他们相信这些面部轮廓的草图吗？

Do they buy these sketches?

研究了基于草图轮廓的拉伸与旋转特征模型重建的生成方法，以实例零件说明本文提出的重建方法是切实可行的。

The generation methods of sketch-based feature model reconstruction are presented in this thesis. Experimental results show that the methods presented here are reliable.

然后再将序列化的轮廓点映射到用户交互绘制的一条草图线上，通过解线性方程组求出变形后各顶点的新坐标。

Then the serialized silhouette points are projected to a line sketched by the user interactively and the new coordinate of vertices are achieved after solving the linear equations.
