我要寻找一个开源IK库AS3线索。

I am looking for leads on an Open Source IK library for AS3.

我的项目涉及简单的 2D 肢体肩/肘/腕关节。

My project involves simple 2D limbs with shoulder/elbow/wrist joints.

如果我无法找到任何东西我会尝试写一个，虽然我的数学是不是附近的任何地方能够胜任工作。

If I am unable to find anything I am going to try and write one, although my math is not anywhere near up to the task.

任何线索，以现有的库和/或相应的源材料将AP preciated！

Any leads to existing libraries and/or appropriate source material would be appreciated!

推荐答案

您可以创建与余弦定理反向运动的解决方案： http://en.wikipedia.org/wiki/Cosine_formula

You could create an Inverse Kinematics solution with the Law of Cosines: http://en.wikipedia.org/wiki/Cosine_formula

这是AS3的实施可以在这里找到： http://www.kynd.info/library/mathandphysics/inverseKinematics_01/

An AS3 implementation can be found here: http://www.kynd.info/library/mathandphysics/inverseKinematics_01/

此创建一个通用的IK-类不应该是硬

Creating a generic IK-class from this shouldn't be to hard
