XMVector3TransformStream

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

Syntax

XMFLOAT4* XMVector3TransformStream(
         XMFLOAT4 *pOutputStream,
         size_t OutputStride,
         const XMFLOAT3 *pInputStream,
         size_t InputStride,
         size_t VectorCount,
         CXMMATRIX M
)  

Parameters

pOutputStream
Type: XMFLOAT4 *

[out]

Address of the first XMFLOAT4 in the destination stream.

OutputStride
Type: size_t 

[in]

Stride, in bytes, between vectors in the destination stream.

pInputStream
Type: XMFLOAT3 *

[in]

Address of the first XMFLOAT3 in the stream to be transformed.

InputStride
Type: size_t 

[in]

Stride, in bytes, between vectors in the input stream.

VectorCount
Type: size_t 

[in]

Number of vectors to transform.

M
Type: CXMMATRIX 

[in]

Transformation matrix.

Return value

Type: XMFLOAT4 *

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).
