Transforms a stream of 2D vectors by a given matrix.
XMFLOAT4 *XM_CALLCONV XMVector2TransformStream( XMFLOAT4 *pOutputStream, size_t OutputStride, const XMFLOAT2 *pInputStream, size_t InputStride, size_t VectorCount, FXMMATRIX M );
Address of the first XMFLOAT4 in the destination stream.
Stride, in bytes, between vectors in the destination stream.
Address of the first XMFLOAT2 in the stream to be transformed.
Stride, in bytes, between vectors in the input stream.
Number of vectors to transform.
Returns the address of the first XMFLOAT4 in the destination stream.
XMVector2TransformStream 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).
