Computes the product of the first two vectors added to the third vector.

Syntax

XMVECTOR XM_CALLCONV XMVectorMultiplyAdd(
  [in] FXMVECTOR V1,
  [in] FXMVECTOR V2,
  [in] FXMVECTOR V3
) noexcept;

Parameters

[in] V1

Vector multiplier.

[in] V2

Vector multiplicand.

[in] V3

Vector addend.

Return value

Returns the product-sum of the vectors.

Remarks

The following pseudocode demonstrates the operation of the function:

XMVECTOR Result;

Result.x = V1.x * V2.x + V3.x;
Result.y = V1.y * V2.y+ V3.y;
Result.z = V1.z * V2.z+ V3.z;
Result.w = V1.w * V2.w+ V3.w;

return Result;
