Parameters

q Microsoft.DirectX.Quaternion
Source Quaternion structure. See Remarks.
axis Microsoft.DirectX.Vector3
A Vector3 structure that identifies the quaternion's axis of rotation.
angle System.Single
A SingleLeave Site value that identifies the quaternion's angle of rotation, in radians.

Remarks

This method requires unit quaternions.
