Question 2: If, in a simple scene consisting of two non intersecting transparent triangles, it is always possible to find a correct order to draw them, then what is the algorithm that sorts them? Given that a single depth value for each triangle is insufficent to determine the correct order, it feels like there ought to be a simple geometric solution using all three vertices. Unfortunately my maths head seems to be in the wash today.
