XMVector2Transform method

Transforms a 2D vector by a matrix.

Syntax


XMVECTOR XMVector2Transform(
  [in] XMVECTOR V,
  [in] XMMATRIX M
);

Parameters

V [in]

2D vector.

M [in]

Transformation matrix.

Return value

Returns the transformed vector.

Remarks

XMVector2Transform performs transformations by using the input matrix rows 0 and 1 for rotation and scaling, and row 3 for translation (effectively assuming row 2 is 0). The w component of the input vector is assumed to be 0. The z component of the output vector should be ignored and its w component may be non-homogeneous (!= 1.0).

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.

Namespace
