XMVector3TransformNormalStream method

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

Syntax


XMFLOAT3* XMVector3TransformNormalStream(
  [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

Each vector in the input stream must be normalized.

XMVector3TransformNormalStream performs transformations using the input matrix rows 0, 1, and 2 for rotation and scaling, and ignores row 3.

Platform Requirements
