XMVector2TransformCoord method

Transforms a 2D vector by a given matrix, projecting the result back into w = 1.

Syntax


XMVECTOR XMVector2TransformCoord(
  [in]  XMVECTOR V,
  [in]  XMMATRIX M
);

Parameters

V [in]

2D vector.

M [in]

Transformation matrix.

Return value

Returns the transformed vector.

Remarks

XMVector2TransformCoord performs transformations by using the input matrix row 0 and row 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 1.0. The z component of the returned vector should be ignored and its w component will have a value of 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.
