D3DXVEC3PROJECTARRAY function
Vector of the object from the object space to the screen space.
definition:
D3DXVECTOR3 * WINAPI D3DXVEC3PROJECTARRAY
D3DXVECTOR3 * Pout,
Uint Outstride,
Const D3DxVector3 * PV,
Uint vstride,
Const d3dviewport9 * PViewPort,
Const D3DXMAMATRIX * PPROJECTION,
Const d3dxmatrix * pVIEW,
Const d3dxmatrix * PWORLD,
Uint N
);
parameter:
pout
[IN, OUT] points to the operation result of the D3DXVECTOR3 structure.
Outstride
[in] Output vector array Each vector occupation space size.
PV
[in] Point the vector number of the D3DXVector3 structure.
Vstride
[in] Input vector array Each vector is occupied.
PViewPort
[in] Points to the D3DViewPort9 structure, which is a viewport.
PPROJECTION
[in] points to the D3DXMAMATRIX structure, which is a projection matrix.
PVIEW
[in] Points to the D3DXMatrix structure, which is the transformation matrix.
PWORLD
[in] Points to the D3DXMatrix structure, which is a world transformation matrix.
n
[in] Many vector in vector arrays.
return value:
Pointing the vector array of D3DXVector3 structure, which is the result of the object of the object from the object space to the screen space.
Description:
The function return value is the same as the POUT parameter. This allows the function D3DXVEC3ProjectArray to use the parameters of other functions.
