D3DXVec3Project function (D3DX10Math.h)

  • Article

Note

The D3DX10 utility library is deprecated. We recommend that you use DirectXMath instead.

Projects a 3D vector from object space into screen space.

Syntax

D3DXVECTOR3* D3DXVec3Project(
  _Inout_       D3DXVECTOR3    *pOut,
  _In_    const D3DXVECTOR3    *pV,
  _In_    const D3D10_VIEWPORT *pViewport,
  _In_    const D3DXMATRIX     *pProjection,
  _In_    const D3DXMATRIX     *pView,
  _In_    const D3DXMATRIX     *pWorld
);

Parameters

pOut [in, out]

Type: D3DXVECTOR3*

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

pV [in]

Type: const D3DXVECTOR3*

Pointer to the source D3DXVECTOR3 structure.

pViewport [in]

Type: const D3D10_VIEWPORT*

Pointer to a D3D10_VIEWPORT, 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.

Return value

Type: D3DXVECTOR3*

Pointer to a D3DXVECTOR3 structure that is the vector 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 D3DXVec3Project function can be used as a parameter for another function.
