Should these be seen as just a convention or is there any reasoning behind this?
I am having a hard time understanding this idea of breaking ties. Could you be more specific and provide concrete examples that relate to the image on this slide? Thank you.
How can we determine whether an edge is top/bottom/left/right edge?
What happens when you have a triangle with one top edge and one left edge? How do we break ties with the third edge? What is that third edge called?
How do we decide if an edge is horizontal or not?
How could a triangle have 2 left sides?
Which of these triangles are left edge triangles and which are top edge triangles?
I don't quite understand what "edge falls on a sample point" mean. Why the two small triangles at the top do not cover any pixels?
