minus-squareVegOwOtenks@lemmy.worldlinkfedilinkEnglisharrow-up8·2 days agoI 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.
