D3DXVec2Lerp function

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.
