Note

The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.

Projects an array (x, y, z, 0) from object space into screen space.

Syntax

D3DXVECTOR3* D3DXVec3ProjectArray(
  _Inout_       D3DXVECTOR3  *pOut,
  _In_          UINT         OutStride,
  _In_    const D3DXVECTOR3  *pV,
  _In_          UINT         VStride,
  _In_    const D3DVIEWPORT9 *pViewport,
  _In_    const D3DXMATRIX   *pProjection,
  _In_    const D3DXMATRIX   *pView,
  _In_    const D3DXMATRIX   *pWorld,
  _In_          UINT         n
);

Parameters

pOut [in, out]

Type: D3DXVECTOR3*

Pointer to the D3DXVECTOR3 structure that is the result of the operation.

OutStride [in]

Type: UINT

Stride between vectors in the output data stream.

pV [in]

Type: const D3DXVECTOR3*

Pointer to the source D3DXVECTOR3 structure.

VStride [in]

Type: UINT

Stride between vectors in the input data stream.

pViewport [in]

Type: const D3DVIEWPORT9*

Pointer to a D3DVIEWPORT9 structure, representing the viewport.

pProjection [in]

Type: const D3DXMATRIX*

Pointer to a D3DXMATRIX structure, representing the projection matrix.

pView [in]

Type: const D3DXMATRIX*

Pointer to a D3DXMATRIX structure, representing the view matrix.

pWorld [in]

Type: const D3DXMATRIX*

Pointer to a D3DXMATRIX structure, representing the world matrix.

n [in]

Type: UINT

Number of elements in the array.

Return value

Type: D3DXVECTOR3*

Pointer to a D3DXVECTOR3 structure that is the array projected from object space to screen space.

Remarks

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec3ProjectArray function can be used as a parameter for another function.
