I'm a bit confused on the notation here. Is K_i the sum of squared distances to the triangles that contain vertex i?

If so, wouldn't this algorithm favor collapsing edges at locations where there already aren't a lot of triangles? Because the quadric error doesn't normalize based on number of triangle.

What are the planes we are measuring square distances from?
