XMVectorCatmullRomV

Performs a Catmull-Rom interpolation, using the specified position vectors.

Syntax

XMVECTOR XMVectorCatmullRomV(
         XMVECTOR Position0,
         XMVECTOR Position1,
         XMVECTOR Position2,
         GXMVECTOR Position3,
         XMVECTOR T
)  

Parameters

Position0
Type: XMVECTOR 

First position.

Position1
Type: XMVECTOR 

Second position.

Position2
Type: XMVECTOR 

Third position.

Position3
Type: GXMVECTOR 

Fourth position.

T
Type: XMVECTOR 

Interpolating control factor for the corresponding components of the position.

Return value

Type: XMVECTOR 

Returns the results of the Catmull-Rom interpolation.

Remarks

This function is identical to XMVectorCatmullRom except that independent weighting factors may supplied in T. As an example, you might want to calculate two sets of Catmull-Rom 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 Catmull-Rom interpolation. Similarly, the z and w-components of T would determine the interpolation factors for the second Catmull-Rom interpolation.
