operator*() [1/2]

Point4 operator* ( float  f, const Point4 &  a  )

inline

Remarks

Returns a Point4 that is the specified Point4 multiplied by the specified float.

{
    return (Point4(a.x * f, a.y * f, a.z * f, a.w * f));
}

inline

Remarks

Returns a Point4 that is the specified Point4 divided by the specified float.

{
    DbgAssert(f != 0.0f);
    float invF = 1.0f / f; // Mimic 2019 behavior
