Parameters

VOut

D3DVECTOR4 type that is the result of the operation.

V0

D3DVECTOR4 type, a position vector.

V1

D3DVECTOR4 type, a position vector.

V2

D3DVECTOR4 type, a position vector.

V3

D3DVECTOR4 type, a position vector.

s

Weighting factor. See Remarks.

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

The D3DXVec4CatmullRom function interpolates between the position V1 when s is equal to 0, and between the position V2 when s is equal to 1, using Catmull-Rom interpolation.
