e/Axis angle

Information
has gloss	eng: The axis angle (or rotation vector) representation of a rotation, also known as the exponential coordinates of a rotation, parameterizes a rotation by two values: a unit vector indicating the direction of a directed axis (straight line), and an angle describing the magnitude of the rotation about the axis. The rotation occurs in the sense prescribed by the right hand grip rule.
lexicalization	eng: axis angle
lexicalization	eng: Axis-angle
instance of	(noun) a system that uses coordinates to establish position reference system, coordinate system, frame of reference, reference frame

Meaning
Chinese
has gloss	zho: 旋转的轴角表示用两个值参数化了旋转: 一个轴或直线，和描述绕这个轴的旋转量的一个角。它也叫做旋转的指数坐标。有时也叫做旋转向量表示，因为这两个参数(轴和角)可用在这个轴上的其模是旋转角的一个向量来表示。
lexicalization	zho: 轴角
