Namespace Detail

SpiderGL.Math.Quat
The SpiderGL.Math.Quat namespace. The provided functions operate on quaternions, represented as standard JavaScript arrays of length 4. The identity quaternion is represented as the vector [0, 0, 0, 1].

Method Detail

  • <static> SpiderGL.Math.Quat.copy$(p, q)
    Parameters:
    p
