abbr.自由变形（FreeFormDeformation）；操作流程图（functionalflowdiagram）
Direct manipulation of FFD improves controllability and efficiency of the deformation.───FFD的直接操作为变形提供了更直观更方便的控制手段。
Body modeling and FFD (Free form Deformation) methods are key techniques in the field of body digitalization.───人体曲面建模与自由变形方法是实现人体数字化的关键技术。
The secondary outcome measure was FFD (Finger-floor distance).───次要测量指标FFD（指地距）。
We improved FFD extrapolation operator to compensate the amplitude difference generated by geometry diffusion loss.───通过改进傅立叶有限差分的延拓算子，补偿了几何扩散损失引起的振幅误差。
Also, as it appears in the picture above, as soon as the lava exits the FFD box, it will pop back to its unmodified position.───另外，正如它像上图一样，一旦岩浆模型离开FFD变形盒的空间，它将返回未修改时的位置。
I formed the planes to follow the slopes using primitive tools such as FFD box.───我形成了飞机走斜坡发展筹资框使用原始的工具，如。
Based on the rational approximation of the FFD operator, we extend the two coefficients to be optimized to four coefficients, then we optimize them globally using simulated annealing algorithm.
