Quaternion.magnitude介绍

[英]Return the magnitude of this quaternion, i.e. sqrt( #magnitude())

A magnitude of zero shall equal #isIdentity(), as performed by #normalize().

Implementation Details:

• returns 0f if #magnitudeSquared() is FloatUtil#isZero(float,float) using FloatUtil#EPSILON
• returns 1f if #magnitudeSquared() is FloatUtil#isEqual(float,float,float) using FloatUtil#EPSILON
  [中]返回此四元数的大小，即sqrt（#magnity（））
  如#normalize（）所示，零值应等于#isIdentity（）。
  实施细节：
  *如果#magnitudeSquared（）为FloatUtil#为零（float，float），则使用FloatUtil#EPSILON返回0f
  *如果#magnitudeSquared（）是FloatUtil#isEqual（float，float，float），则使用FloatUtil#EPSILON返回1f
