Target Normal, Couple U to ROT:
(Default) Represents most common type of surface body contact. Constraints are constructed to couple the translational and rotational DOFs. In most types of surface body contact, an offset will exist. Due to this offset there will be a moment created. To get the correct moment, the rotation/displacement DOF's must be coupled together. If the program cannot detect any contact in the target normal direction, it will then search anywhere inside the pinball for contact.

呵呵。
u = displacement. rot = rotation

理解成"平动"。

为何???

u = displacement = 位移 ????

displacement 里面没有半个字母 u

U to ROT

u 跟 rotation 不可能指同样的东西吧?

您应该打错了吧?
