D3DXVec4Lerp

Performs a linear interpolation between two 4-D vectors.

D3DXVec4Lerp( _ 
    VOut As D3DVECTOR4, _ 
    V1 As D3DVECTOR4, _ 
    V2 As D3DVECTOR4, _ 
    s As Single)

Parameters

VOut

D3DVECTOR4 type that is the result of the operation, the linear interpolation.

V1

A source D3DVECTOR4 type.

V2

A source D3DVECTOR4 type.

s

Parameter that linearly interpolates between the vectors.

Error Codes

If the function fails, an error is raised and Err.Number can be set to one of the following values.

For information on trapping errors, see the Microsoft® Visual Basic® Error Handling topic.

Remarks

This function performs the linear interpolation based on the following formula: V1 + s(V2-V1).
