XMVector2TransformCoordStream function (directxmath.h)
Transforms a stream of 2D vectors by a given matrix, projecting the resulting vectors such that their w coordinates are equal to 1.0.
XMFLOAT2 *XM_CALLCONV noexcept XMVector2TransformCoordStream( XMFLOAT2 *pOutputStream, size_t OutputStride, const XMFLOAT2 *pInputStream, size_t InputStride, size_t VectorCount, FXMMATRIX M );
Address of the first XMFLOAT2 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 XMFLOAT2 in the destination stream.
XMVector2TransformCoordStream 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.
