# XMVectorHermiteV function

Performs a Hermite spline interpolation, using the specified vectors.

## Syntax

```
XMVECTOR XM_CALLCONV XMVectorHermiteV(
FXMVECTOR Position0,
FXMVECTOR Tangent0,
FXMVECTOR Position1,
GXMVECTOR Tangent1,
HXMVECTOR T
);
```

## Parameters

`Position0`

First position to interpolate from.

`Tangent0`

Tangent vector for the first position.

`Position1`

Second position to interpolate from.

`Tangent1`

Tangent vector for the second position.

`T`

Interpolating control factor with each component corresponding to a term of the Hermite equation.

## Return Value

Returns a vector containing the interpolation.

## Remarks

This function is identical to XMVectorHermite except that independent weighting factors may be supplied in *T*. As an example, you might want to calculate two sets of Hermite spline interpolation, using the x and y-components of the position vectors for one set of 2D positions and the z and w-components of the position vectors for the other set of 2D positions. The x and y-components of *T* would determine the interpolation factors for the first Hermite spline interpolation. Similarly, the z and w-components of *T* would determine the interpolation factors for the second Hermite spline interpolation.

The following pseudocode demonstrates the operation of the function:

```
Result[i] = (2*(T.x)^3 - 3*(T.x)^2 + 1) * Position0.[i]
+ ((T.y)^3 - 2*(T.y)^2 + (T.y)) * Tangent0.[i]
+ (-2*(T.z)^3 + 3*(T.z)^2) * Position1.[i]
+ ((T.w)^3 - *(T.w)^2) * Tangent1.[i]
```
