Function directx_math::XMVectorMultiplyAdd

pub fn XMVectorMultiplyAdd(
    V1: FXMVECTOR, 
    V2: FXMVECTOR, 
    V3: FXMVECTOR
) -> XMVECTOR

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

Parameters

V1 Vector multiplier.

V2 Vector multiplicand.

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;
