How to read the Loop's subdivision
I read about the Loop's subdivision but I kept having problem understanding it.
In almost everywhere I searched for info, they wrote that I need to "choose locations for new vertices as weighted average of original vertices in local neighbourhood". ![]() However, I don't understand at all how to choose locations and what weighted average are they referring to. And what are those numbers around the vertices represent and how are they derived? On a website I found, I see this image: ![]() The algebras around the edges seem to try to tell how those fractions around the vertices are derived. However, I am still not sure what the alpha and "n" variables are referring to. For a start, what are these alpha and "n" variables referring to? How do I get these values and what do these eventual fractions around the vertices meant for? Thanks for any help! |
