XMQuaternionExp function (directxmath.h)

Computes the exponential of a given pure quaternion.

Syntax

XMVECTOR XM_CALLCONV XMQuaternionExp(
  [in] FXMVECTOR Q
) noexcept;

Parameters

[in] Q

Pure quaternion for which to compute the exponential. The w-component of the input quaternion is ignored in the calculation.

Return value

Returns the exponential of Q.

Remarks

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.
