D3DXVec2Lerp function
Note
The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.
Performs a linear interpolation between two 2D vectors.
Syntax
D3DXVECTOR2* D3DXVec2Lerp(
_Inout_ D3DXVECTOR2 *pOut,
_In_ const D3DXVECTOR2 *pV1,
_In_ const D3DXVECTOR2 *pV2,
_In_ FLOAT s
);
Parameters
-
pOut [in, out]
-
Type: D3DXVECTOR2*
Pointer to the D3DXVECTOR2 structure that is the result of the operation.
-
pV1 [in]
-
Type: const D3DXVECTOR2*
Pointer to a source D3DXVECTOR2 structure.
-
pV2 [in]
-
Type: const D3DXVECTOR2*
Pointer to a source D3DXVECTOR2 structure.
-
s [in]
-
Type: FLOAT
Parameter that linearly interpolates between the vectors.
Return value
Type: D3DXVECTOR2*
Pointer to a D3DXVECTOR2 structure that is the result of the linear interpolation.
Remarks
This function performs the linear interpolation based on the following formula: V1 + s(V2-V1).
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec2Lerp function can be used as a parameter for another function.
