XMVector3TransformCoordStream method
Transforms a stream of 3D vectors by a given matrix, projecting the resulting vectors such that their w coordinates are equal to 1.0.
Syntax
XMFLOAT3* XMVector3TransformCoordStream( [out] XMFLOAT3 *pOutputStream, [in] size_t OutputStride, [in] const XMFLOAT3 *pInputStream, [in] size_t InputStride, [in] size_t VectorCount, [in] XMMATRIX M );
Parameters
- pOutputStream [out]
-
Address of the first XMFLOAT3 in the destination stream.
- OutputStride [in]
-
Stride, in bytes, between vectors in the destination stream.
- pInputStream [in]
-
Address of the first XMFLOAT3 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]
-
Transformation matrix.
Return value
Returns the address of the first XMFLOAT3 in the destination stream.
Remarks
XMVector3TransformCoordStream ignores the w component of the input vector, and uses a value of 1.0 instead. The w component of the returned vectors will always be 1.0.
Platform Requirements
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.
