D3DXVec2Lerp
Microsoft DirectX 9.0 SDK Update (October 2004)

D3DXVec2Lerp Function


Performs a linear interpolation between two 2-D vectors.

Syntax

D3DXVECTOR2 *D3DXVec2Lerp(      

    D3DXVECTOR2 *pOut,     CONST D3DXVECTOR2 *pV1,     CONST D3DXVECTOR2 *pV2,     FLOAT s );

Parameters

pOut
[in, out] Pointer to the D3DXVECTOR2 structure that is the result of the operation.
pV1
[in] Pointer to a source D3DXVECTOR2 structure.
pV2
[in] Pointer to a source D3DXVECTOR2 structure.
s
[in] Parameter that linearly interpolates between the vectors.

Return Value

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.
