    I don’t really understand your first point.

    n can be determined according to this equation: f + n + m = 1, and all the values are bounded by [0; 1] additionally.

    The cross product gives you the orthogonal vector, this is why they take the absolute value of it.

      i think the equation actually is f² + n² + m² = 1
