XMVector2Transform

Transforms a 2D vector by a matrix.

Syntax

XMVECTOR XMVector2Transform(
         XMVECTOR V,
         CXMMATRIX M
)  

Parameters

V
Type: XMVECTOR 

2D vector.

M
Type: CXMMATRIX 

Transformation matrix.

Return value

Type: XMVECTOR 

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).
