[−][src]Function directx_math::XMVectorHermiteV
pub fn XMVectorHermiteV(
Position0: FXMVECTOR,
Tangent0: FXMVECTOR,
Position1: FXMVECTOR,
Tangent1: GXMVECTOR,
T: HXMVECTOR
) -> XMVECTOR
Performs a Hermite spline interpolation, using the specified vectors.
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]
