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 Solveris 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 andorientation 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.
