Performs a Hermite spline interpolation, using the specified vectors.
First position to interpolate from.
Tangent vector for the first position.
Second position to interpolate from.
Tangent vector for the second position.
Interpolation control factor.
Returns a vector containing the interpolation.
The following pseudocode demonstrates the operation of the function:
XMVECTOR Result;
float t2 = t * t;
float t3 = t2* t;
float P0 = 2.0f * t3 - 3.0f * t2 + 1.0f;
float T0 = t3 - 2.0f * t2 + t;
float P1 = -2.0f * t3 + 3.0f * t2;
float T1 = t3 - t2;
Result.x = P0 * Position0.x + T0 * Tangent0.x + P1 * Position1.x + T1 * Tangent1.x;
Result.y = P0 * Position0.y + T0 * Tangent0.y + P1 * Position1.y + T1 * Tangent1.y;
Result.z = P0 * Position0.z + T0 * Tangent0.z + P1 * Position1.z + T1 * Tangent1.z;
Result.w = P0 * Position0.w + T0 * Tangent0.w + P1 * Position1.w + T1 * Tangent1.w;
return Result;
