这是我用来记录包含一些计算的点的代码。所以是的，我得到了点的值位置，做一些数学运算，然后将它们保存到一个列表中。

gesture.L.E.AddFrameDescriptor(
    joints[JointType.ElbowLeft].Position.X, joints[JointType.ElbowLeft].Position.Y, joints[JointType.ElbowLeft].Position.Z,
    joints[JointType.SpineMid].Position.X, joints[JointType.SpineMid].Position.Y, joints[JointType.SpineMid].Position.Z,
    spineBaseShoulderRHO
    );
gesture.L.W.AddFrameDescriptor(
    joints[JointType.WristLeft].Position.X, joints[JointType.WristLeft].Position.Y, joints[JointType.WristLeft].Position.Z,
    joints[JointType.SpineMid].Position.X, joints[JointType.SpineMid].Position.Y, joints[JointType.SpineMid].Position.Z,
    spineBaseShoulderRHO
    );
gesture.L.H.AddFrameDescriptor(
    joints[JointType.HandTipLeft].Position.X, joints[JointType.HandTipLeft].Position.Y, joints[JointType.HandTipLeft].Position.Z,
    joints[JointType.SpineMid].Position.X, joints[JointType.SpineMid].Position.Y, joints[JointType.SpineMid].Position.Z,
    spineBaseShoulderRHO
    );


gesture.R.E.AddFrameDescriptor(
    joints[JointType.ElbowRight].Position.X, joints[JointType.ElbowRight].Position.Y, joints[JointType.ElbowRight].Position.Z,
    joints[JointType.SpineMid].Position.X, joints[JointType.SpineMid].Position.Y, joints[JointType.SpineMid].Position.Z,
    spineBaseShoulderRHO
    );
gesture.R.W.AddFrameDescriptor(
    joints[JointType.WristRight].Position.X, joints[JointType.WristRight].Position.Y, joints[JointType.WristRight].Position.Z,
    joints[JointType.SpineMid].Position.X, joints[JointType.SpineMid].Position.Y, joints[JointType.SpineMid].Position.Z,
    spineBaseShoulderRHO
    );
gesture.R.H.AddFrameDescriptor(
    joints[JointType.HandTipRight].Position.X, joints[JointType.HandTipRight].Position.Y, joints[JointType.HandTipRight].Position.Z,
    joints[JointType.SpineMid].Position.X, joints[JointType.SpineMid].Position.Y, joints[JointType.SpineMid].Position.Z,
    spineBaseShoulderRHO
    );

出于某种原因，我得到了很多重复的值，重复了 20 次。我注意到如果我只保存一个值，我会得到重要的值并且没有更多的重复，加上值的差异更接近于彼此，比如 0.05513 然后 0.05413 与那些重复的值相比，一旦我得到 20 个 0.05513 然后下一个是 20 0.05013。

编辑如果我将多个值存储到列表中，这是我得到的示例值。

0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.399695181 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401078759 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401423597 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625 0.401669625

如您所见，这些数字重复了二十次。
