QuaternionD Struct

Namespace: VRageMath
Assembly: VRage.Math.dll

Summary

Defines a four-dimensional vector (x,y,z,w), which is used to efficiently rotate an object about the (x, y, z) vector by the angle theta, where w = cos(theta/2). Uses double precision floating point numbers for calculation and storage

Fields

_double X_	Specifies the x-value of the vector component of the quaternion.
_double Y_	Specifies the y-value of the vector component of the quaternion.
_double Z_	Specifies the z-value of the vector component of the quaternion.
_double W_	Specifies the rotation component of the quaternion.
