Quaternion.toMatrix介绍

[英]Transform this quaternion to a normalized 4x4 column matrix representing the rotation.

Implementation Details:

  • makes identity matrix if #magnitudeSquared() is FloatUtil#isZero(float,float) using FloatUtil#EPSILON
    [中]将此四元数转换为表示旋转的规格化4x4列矩阵。
    实施细节：
    *如果#magnitudeSquared（）为FloatUtil#为零（float，float），则使用FloatUtil#EPSILON生成单位矩阵
