IK Solver Constraint 反向运动学约束

反向运动学(IK) 约束实现 反向运动学(IK) 骨骼姿势技术。因此,它仅仅适用于骨骼。要快速用一个目标(target)创建一个IK约束,在姿势模式下,选择一根骨骼,按Shift-I。

此约束的完整文档在rigging章节 Inverse Kinematics 页部分。

iTaSC Solver

If the iTaSC IK Solver is used, the IK Solver Constraint changes to add these addition parameters.

IK Type
Copy Pose

Equivalent to the traditional end effector position and orientation constraint: the end effector is constrained to take the position, and optionally the orientation, of a given target, which is set in the target field.

Position/Rotation Locking

Allows to obtain various effect by not constraining the coordinates along certain axis.

Axis Reference

Specifies how to compute the axis coordinates.

Bone
The coordinates are the position and orientation of the target relative to the bone.
Target 目标
The opposite of Bone, the coordinates are the position and orientation of the tip of the bone relative to the target.
Distance

Specify that the end effector will stay inside, at, or outside a sphere centered on the target object.

Limit Mode
Inside
The end effector will stay inside of the distance from the target object.
Outside
The end effector will stay outside of the distance from the target object.
On Surface
The end effector will stay exactly at the distance from the target object.
Distance
The radius from the target object.

Note

The Influence parameter is not implemented if Pole Target is used.
