Transforms a stream of 2D vectors by a given matrix.
XMFLOAT4* XMVector2TransformStream( [out] XMFLOAT4 *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 XMFLOAT4 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 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).
Microsoft Visual Studio 2010 or Microsoft Visual Studio 2012 with the Windows SDK for Windows 8. Supported for Win32 desktop apps, Windows Store apps, and Windows Phone 8 apps.
