XMQuaternionRotationNormal function

Computes the rotation quaternion about a normal vector.


XMVECTOR XM_CALLCONV XMQuaternionRotationNormal(
  FXMVECTOR NormalAxis,
  float     Angle



Normal vector describing the axis of rotation.


Angle of rotation in radians. Angles are measured clockwise when looking along the rotation axis toward the origin.

Return Value

Returns the rotation quaternion.


The DirectXMath quaternion functions use an XMVECTOR 4-vector to represent quaternions, where the X, Y, and Z components are the vector part and the W component is the scalar part.

Platform Requirements

Microsoft Visual Studio 2010 or Microsoft Visual Studio 2012 with the Windows SDK for Windows 8. Supported for Win32 desktop apps, Windows Store apps, and Windows Phone 8 apps.
