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* XMVector2TransformCoordStream( [out] XMFLOAT2 *pOutputStream, [in] size_t OutputStride, [in] const XMFLOAT2 *pInputStream, [in] size_t InputStride, [in] size_t VectorCount, [in] XMMATRIX M );
- pOutputStream [out]
Address of the first XMFLOAT2 in the destination stream.
- OutputStride [in]
Stride, in bytes, between vectors in the destination stream.
- pInputStream [in]
Address of the first XMFLOAT2 in the stream to be transformed.
- InputStride [in]
Stride, in bytes, between vectors in the input stream.
- VectorCount [in]
Number of vectors to transform.
- M [in]
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.
