XMVectorNegativeMultiplySubtract function (directxmath.h)

  • Article

Computes the difference of a third vector and the product of the first two vectors.

Syntax

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

Parameters

[in] V1

Vector multiplier.

[in] V2

Vector multiplicand.

[in] V3

Vector subtrahend.

Return value

Returns the resulting vector. See the remarks.

Remarks

The following pseudocode demonstrates the operation of the function:

XMVECTOR result;

result.x = V3.x - V1.x * V2.x;
result.y = V3.y - V1.y * V2.y;
result.z = V3.z - V1.z * V2.z;
result.w = V3.w - V1.w * V2.w;

return result;
