D3DXVEC3PROJECT function
Vector of the object from the object space to the screen space.
definition:
D3DXVECTOR3 * WINAPI D3DXVEC3PROJECT
D3DXVECTOR3 * Pout,
Const D3DxVector3 * PV,
Const d3dviewport9 * PViewPort,
Const D3DXMAMATRIX * PPROJECTION,
Const d3dxmatrix * pVIEW,
Const d3dxmatrix * PWORLD
);
parameter:
pout
[IN, OUT] points to the operation result of the D3DXVECTOR3 structure.
PV
[in] Point the source vector of the D3DXVECTOR3 structure.
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.
return value:
Pointing the vector of the 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 function D3DXVEC3Project to use parameters of other functions.
