XMVector3TransformCoordStream

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

Parameters

pOutputStream
Type: XMFLOAT3 *

[out]

Address of the first XMFLOAT3 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: XMFLOAT3 *

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.
