XMVector2TransformCoord

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

Syntax

XMVECTOR XMVector2TransformCoord(
         XMVECTOR V,
         CXMMATRIX M
)  

Parameters

V
Type: XMVECTOR 

2D vector.

M
Type: CXMMATRIX 

Transformation matrix.

Return value

Type: XMVECTOR 

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.
