Do we have to minimize the quadric error when we implement edge collapse in Assignment 2?
I misunderstood this slide when last we had lecture. I had thought what it was saying is 'When looking to simplify a mesh, find the edge who's midpoint produces the least quadric error and collapse that'. What I read now is 'Whenever you collapse an edge, find the point on that edge that produces the least quadric error and make that point the new vertex.' Is this accurate?
@bunbohue It is not necessary for the edge collapse operation.
@Parker Yes, this is accurate. The midpoint of an edge is not generally the "best" choice for the new vertex. As you said, you should instead look for the point that minimizes the quadric error.
