XMVectorHermite method
Performs a Hermite spline interpolation, using the specified vectors.
Syntax
XMVECTOR XMVectorHermite( [in] XMVECTOR Position0, [in] XMVECTOR Tangent0, [in] XMVECTOR Position1, [in] XMVECTOR Tangent1, [in] float t );
Parameters
- Position0 [in]
-
First position to interpolate from.
- Tangent0 [in]
-
Tangent vector for the first position.
- Position1 [in]
-
Second position to interpolate from.
- Tangent1 [in]
-
Tangent vector for the second position.
- t [in]
-
Interpolation control factor.
Return value
Returns a vector containing the interpolation.
Remarks
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;
