XMVector3TransformStream method

Transforms a stream of 3D vectors by a given matrix.

Syntax


XMFLOAT4* XMVector3TransformStream(
  [out]       XMFLOAT4 *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 XMFLOAT4 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 XMFLOAT4 in the destination stream.

Remarks

XMVector3TransformStream ignores the w component of the input vector, and uses a value of 1.0 instead. The w component of the returned vectors may be non-homogeneous (!= 1.0).

Platform Requirements
