XMVector3TransformCoordStream function

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 *XM_CALLCONV XMVector3TransformCoordStream(
  XMFLOAT3       *pOutputStream,
  size_t         OutputStride,
  const XMFLOAT3 *pInputStream,
  size_t         InputStride,
  size_t         VectorCount,
  FXMMATRIX      M
);

Parameters

pOutputStream

Address of the first XMFLOAT3 in the destination stream.

OutputStride

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

pInputStream

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

InputStride

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

VectorCount

Number of vectors to transform.

M

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.
