Jointのタイプとindex番号の対応はSkelton.hに書いてある。

enum JointType
{
	JOINT_NONE				= 0, ///< Reserved joint (unused).
	JOINT_HEAD				= 1, ///< Head
	JOINT_NECK				= 2, ///< Neck
	JOINT_TORSO				= 3, ///< Torso
	JOINT_WAIST				= 4, ///< Waist
	JOINT_LEFT_COLLAR		= 5, ///< Left collar
	JOINT_LEFT_SHOULDER		= 6, ///< Left shoulder
	JOINT_LEFT_ELBOW		= 7, ///< Left elbow
	JOINT_LEFT_WRIST		= 8, ///< Left wrist
	JOINT_LEFT_HAND			= 9, ///< Left hand
	JOINT_LEFT_FINGERTIP	= 10, ///< Left fingertip (<b>not used in the current version</b>).
	JOINT_RIGHT_COLLAR		= 11, ///< Right collar
	JOINT_RIGHT_SHOULDER	= 12, ///< Right shoulder
	JOINT_RIGHT_ELBOW		= 13, ///< Right elbow
	JOINT_RIGHT_WRIST		= 14, ///< Right wrist
	JOINT_RIGHT_HAND		= 15, ///< Right hand
	JOINT_RIGHT_FINGERTIP	= 16, ///< Right fingertip (<b>not used in the current version</b>).
	JOINT_LEFT_HIP			= 17, ///< Left hip
	JOINT_LEFT_KNEE			= 18, ///< Left knee
	JOINT_LEFT_ANKLE		= 19, ///< Left ankle
	JOINT_LEFT_FOOT			= 20, ///< Left foot (<b>not used in the current version</b>).
	JOINT_RIGHT_HIP			= 21, ///< Right hip
	JOINT_RIGHT_KNEE		= 22, ///< Right knee
	JOINT_RIGHT_ANKLE		= 23, ///< Right ankle
	JOINT_RIGHT_FOOT		= 24 ///< Right foot (<b>not used in the current version</b>).
};

実際にoFで動かして番号を取得してみたところ下記のようになりました。

気づいたことは、5番（JOINT_LEFT_COLLAR）がないんですよね。11番のJOINT_RIGHT_COLLARだけ。5は使われてないっぽい。
